When choosing a gutter system for your home, gutters made of PPGI/PPGL are considered a durable and long-lasting option compared to traditional materials such as aluminum or plastic. In this article, let's explore the advantages and disadvantages of using PPGI/PPGL for gutters, and take a closer look at the installation process, maintenance, and cost with MRS Steel.What are gutters? Which materials are suitable for gutters?Gutters are a term describing the drainage system of a house, typically installed at elevated positions such as on the roof to collect rainwater and shape the flow in the desired direction. There are various suitable materials for making gutters, with aluminum and plastic being typical examples. Aluminum gutters are often lightweight and can withstand harsh weather conditions, while plastic gutters are lightweight, easy to install, and unaffected by corrosion or rust, providing a cost-effective solution.In addition to the traditional gutter materials mentioned above, manufacturers have also designed another durable material to cater to gutter applications. Gutters made of PPGI/PPGL are specifically crafted to operate efficiently when combined with steel roofs, especially when using the same PPGI/PPGL material. Furthermore, the installation process for gutters made from PPGI/PPGL often requires specific considerations to allow for expansion and contraction, given the nature of steel as a metal.Benefits of using PPGI/PPGL for guttersUtilizing PPGI/PPGL materials for gutters brings not only a range of benefits in terms of durability and long lifespan but also meets the aesthetic needs of a home. This material is designed with special protective layers to resist corrosion from sunlight, rain, wind, and harsh weather, providing a comprehensive and versatile solution for gutter systems.Harmonizing with metal roofing, enhancing aesthetic appeal for constructionWhen gutters and roofs are made from the same PPGI/PPGL material, it creates a cohesive design in terms of color, patterns, and quality. This harmonious combination not only produces a unified appearance but also delivers a unique and modern aesthetic impression, making the home stand out and appear exceptional in its surroundings.High-quality zinc-aluminum coating and paint layers play a crucial role in protecting PPGI/PPGL gutters from the impact of sunlight. This not only prevents color fading but also maintains the color of the gutters over time. The stable color retention contributes not only to enhancing the durability of the drainage system but also to the overall appearance of the home.Durable for a long lifespanThe clear difference between traditional gutters and PPGI/PPGL gutters lies primarily in their lifespan. Specifically, traditional gutters, often made from aluminum or plastic, typically last for 10-20 years, whereas PPGI/PPGL gutters have the potential to extend their lifespan to over 50 years, thanks to their outstanding durability and corrosion resistance.PPGI/PPGL materials are designed to withstand sunlight, rain, snow, and strong winds through the combination of multiple protective layers. In regions with particular climates, especially those with heavy snowfall or strong winds, the robust mechanical structure of PPGI/PPGL gutters helps them withstand the pressure from strong winds without deformation or damage. Additionally, their waterproofing capability ensures that the gutters are not affected by the impact of snow, maintaining stability during winter. Moreover, these protective layers can resist corrosion caused by prolonged exposure to rain, preventing rust and maintaining effective water drainage for the gutters.Minimizing annual maintenance costsWhen considering the initial cost, it is important to note that PPGI/PPGL materials are generally priced higher than some other materials used for gutters. The primary reason for this higher cost stems from the high-quality production process of PPGI/PPGL, which includes the application of multiple protective coatings such as zinc and aluminum. However, when examining the long-term benefits of PPGI/PPGL gutters, such as the ability to maintain form and function effectively over time without requiring significant maintenance costs, this cost is considered worthwhile.All types of gutters require regular maintenance to ensure they can operate efficiently, including cleaning to remove debris or checking for any signs of corrosion or rust. However, PPGI/PPGL gutters tend to incur lower maintenance costs as they are equipped with zinc-aluminum coatings and high-quality paint layers that help prevent oxidation from environmental factors. This has significantly contributed to minimizing repair or maintenance expenses for the product.Looking for a reliable supplier of PPGI/PPGL for gutter installationPPGI/PPGL is a type of steel that undergoes a complex production process with multiple coating stages, requiring detailed techniques to ensure even paint layers and enhance the adhesion of the coating. However, the current market offers numerous suppliers of PPGI/PPGL with varying prices and sizes, posing a challenge for buyers to choose a reputable source that guarantees quality, suitable dimensions, thickness, and colors.Collaborating with a company knowledgeable about specific steel products and possessing years of experience in the galvanized steel sector will provide buyers with more peace of mind regarding product quality.

Pre-engineered steel buildings are becoming increasingly popular in construction projects due to their superior advantages over traditional concrete steel buildings. Let's MRS Steel explore this type of building and its pros and cons in today's article.1. Overview of prefabricated steel buildingsPre-engineered steel buildings refer to a type of house or facility constructed based on pre-manufactured steel components. Once these parts are produced, the construction team transports them to the site for assembly and completion. The entire construction process of a pre-engineered steel house goes through three main stages: design, component fabrication, and on-site assembly. Because of using available steel structures, the construction is faster and requires less manual labor.Compared to traditional houses, pre-engineered steel buildings have a distinct structural system. The main structure includes steel columns and beams designed to bear the load for the walls and roof. Regarding the foundation, which is the primary load-bearing base for the house, the pre-engineered steel homes still use reinforced concrete for their foundation. However, depending on requirements, one can choose for shallow or deep foundations. The supplementary structural system, which enhances the house's completeness, includes partitions, stair-support frames, and roof trusses made from C, Z, or I-beams.The roofing structure is typically made of metal sheets to shield the house from environmental and weather impacts. Commonly, the favored material for these roofs is PPGI/PPGL because of its excellent corrosion resistance and high heat tolerance.2. The outstanding advantages of prefabricated steel buildingsPreviously, prefabricated steel buildings were mainly used for constructions like warehouses, workshops and exhibition halls. However, in recent years, this type of building has become popular for residential purposes due to its flexibility, time efficiency, and affordability.2.1. Cost savingsThe steel houses generally have a lower construction cost than traditional concrete houses. This is because the number of materials used to construct the house is significantly reduced, mainly relying on columns, beams, and trusses for main structural support. Additionally, steel is a durable material, and the anti-rust and oxidation properties coming from galvanized steel can help reduce maintenance costs.2.2. Quick on-site constructionThe design, assembly and construction process of these houses is faster, more precise, and safer than traditional building methods. Main components like columns, beams, and steel bars are pre-manufactured in factories, so when these components are transported to the construction site, the assembly team simply follows the provided instructions.All processes such as cutting, drilling, welding, hole punching, and anti-corrosion painting are performed in the factory by using automated machinery. This means that measurements and quantities are pre-determined based on technical drawings, eliminating direct handling at the construction site and reducing technical errors and safety risks. A small prefabricated steel building can be completed in just a few weeks or even some days, while traditional houses can take several months to finish.2.3. High flexibilityUnlike traditional houses, which are permanent, the steel houses can be easily moved to another location. The structural components are connected with bolts and screws, allowing for easy disassembly and relocation.2.4. The prefabricated steel buildings are a type of multi-purpose houseOne of the outstanding advantages of these buildings is that they do not occupy too much space due to their compact structure. With just the addition of some furniture and fixtures, a comfortable living space can be created. Moreover, this type of house can serve multiple purposes across various sectors, including industrial, commercial, and residential.3. Looking for unit bring steel solution for your prefabricated steel building projectThanks to its flexibility and convenience in construction, as well as its cost-effectiveness, it's considered a solution that overcomes the drawbacks of traditional concrete houses. However, it's worth noting that the prefabricated steel buildings may be less sturdy than concrete houses due to their features such as reasonable costs, versatility, and convenience for various models. Therefore, to build such a house, contractors must find stable ground along with a mild climate to achieve better efficiency.While there are some concerns about sturdiness, selecting quality steel sources from the beginning process for the structural framework can significantly enhance the durability of this type of house. Therefore, choosing companies specialized in steel solutions will bring benefits to pre-engineered steel house construction projects.MRS Steel, with its extensive experience in the steel industry, is your ideal partner for prefabricated steel buildings projects.

K Span is known as a new anti-leak solution for buildings thanks to the steel material PPGI/PPGL in the K Span roofing system helps eliminate the risk of water leakage for the building. Moreover, the durability in them also supports the system becoming sustainable to inclement weather as well as providing flexibility in disassembly and relocation.Definition K Span system and its applicationK Span is the typical name for the dome structure in construction, these domes are manufactured by the forming equipment that makes them reach their full curvature and then the manufacturer will deliver them to the construction site. The entire K Span is a combination of individual pieces of corrugated iron that are connected together by a specialized jointing system, so that the pieces are tightly linked without the need for screws. Normally, the main raw material for making up corrugated iron pieces in K Span is galvanized steel or pre-painted galvanized/galvalume steel (PPGI/PPGL).The K Span system is used a lot in the field of construction, many businesses often apply them to make roofs for civil buildings, houses, barns in agriculture, in addition they can be installed as a hangar or entertainment infrastructure,...Important effects of PPGI/PPGL in the K Span roofing systemAesthetics and durability are one of the outstanding advantages of pre-painted galvanized/galvalume steel. Therefore, the application of PPGI/PPGL in the K Span roofing system has brought a series of beneficial values to the project.Simple construction for contractorSimilar to pre-engineered steel buildings, K Span owns a simple construction structure when they are an overall combination of PPGI/PPGL pieces linked through a joint system. The K Span foundation is built on an extended concrete strip surrounding the building, so the contractor will not need to drive fixed piles or beams during construction.In addition, the main structural components of K Span come from PPGI/PPGI steel, which significantly reduces the weight of the construction compared to traditional brick materials. Thanks to its light weight as well as the simplicity in installing, a K Span system can be set up in almost all soil conditions while still ensuring good stability.Flexibility in design with PPGI/PPGL in the K Span roofing systemThe K Span dome is a combination of a series of coated steel linked together and they are divided according to each span. Thanks to this flexibility, the contractor can arbitrarily change the length of the roofing as desired as they can be dismantled in individual spans. If the building is built with traditional bricks, when the contractor wants to shorten or dismantle it, it will affect the entire structure.Shorten the time for completing projectK Span is considered a system to help improve the construction process quickly because the main structural components are steel and often steel will be produced directly at the factory. After the factory has done the material as required, these parts are moved directly to the construction site, which inadvertently saves the contractor a lot of time during the building process.According to average statistics, a construction team with a number of 10 - 20 people can complete a whole installation of 500m2 per day for a K Span system by assembling the parts together accordingly. Compared with traditional construction methods, construction crews often have to spend more time in mixing mortar and disposing cement.Eliminate the risk of water leakageIn the past, traditional roofs made of mortar or bricks would be prone to leaks because of long standing water absorption. It can be seen that steel is a material that helps to resolve this situation because steel is metal in nature, so it will not absorb liquids. Possessing a K Span dome system will help users feel more secure about waterproofing.In addition, during the production process, the PPGI/PPGL in the K Span roofing system don't create any holes in the surface, there is no chance for rainwater to enter. Tthe curvature of the dome is a great design that provides good drainage when it rains or in snowy environments.High tolerance in the inclement weatherThe applications of steel in construction, especially the PPGI/PPGL in K Span roofing system is often added with galvanized layers to resist scratches as well as increase durability, prevent oxidizing agents due to chemical reaction by zinc. A project with the K Span system will require less frequent maintenance, thereby making conditions for contractors to save on periodic maintenance costs as well as limiting unwanted cost in repair during the process of using.Eco-friendly recyclingConstruction steel is considered a useful material when it can be recycled and reused consecutively throughout its life cycle without being affected by the internal structure. After a long time of use, the contractor can choose to disassemble the pieces of PPGI/PPGL in the K Span roofing system to manufacture other applications.Choose a reputable company to provide PPGI/PPGL in K Span roofing systemClimate change is becoming more obviously forthcoming such as abnormal sunshine and rain as well as high humidity, which directly affects construction works. Therefore, choosing a quality material for your construction project will be the right choice to gain long-term efficiency to the contractors.Understanding the needs of customers, MRS Steel is here to help you find solutions in choosing quality PPGI/PPGL steel materials that come directly from large manufacturers in Vietnam.

The barn is used for many purposes like protecting livestock, storing animal feed, agricultural products or machinery against the environmental elements. Currently, farm owners tend to use PPGI as a barn instead of wood or concrete because of many outstanding advantages.1. Characteristics of barns in agricultureIn the field of agriculture, warehouses are usually designed with 2 floors, the first floor is a shelter for animals or storage of production machinery and equipment. The 2nd floor area is used to store animal feed, agricultural products or other utensils.The barns are named according to the purpose of use, such as tobacco barn, dairy barn, farm barn, tractor barn. The most principal type in the United States is the multipurpose barn, used for housing horses, cows, calves, sheep or storing hay and grain.Wood is the main material in traditional barns, but since World War II, pre-painted galvanized is more increasingly used, especially in large farms because of the advantages of aesthetics, durability and costs.2. Building barn with PPGIWhen building a barn, the roof, door and insulation are essential components that are first considered. The materials that make up these parts of the warehouse will greatly affect the effectiveness of protecting livestock, agricultural products and machinery from the effects of the environment and weather.2.1. RoofThe roof is one of the most important components of the barn because of its role of creating shade, shading the sun and rain and keeping the interior temperature. Most roofs today are constructed from PPGI sheets. With a high-grade coating that does not peel, is durable over time, has the ability to block heat to help keep the interior space cool and temperature stable. Compared to shingles that need to be re-glued every 12-15 years or the wood is prone to rotting, pre-painted galvanized sheets have a long life expectancy, are extremely water and corrosion resistant.2.2. Barn doorThe barn door should be easy to open and to secure. When the weather is favorable, the doors can be fully opened to ventilate the interior space, enhancing the exchange of fresh air for the animals to breathe. The PPGI barn door is very light, easily slides on the rail, saving you time and effort when opening and closing the door.2.3. Thermal and soundproof partition wallsWood, concrete and brick are good insulators but have poor sound insulation. Animals such as horses, cows, sheep,... are very sensitive to sounds, easily panic and lose control in noisy environments. Therefore, ranchers are gradually turning to PPGI to make soundproof walls for different types of barns.3. Advantages of PPGI barn 3.1. Moisture ResistanceHumidity and severe weather can affect the structural integrity of the barn. Wood is porous, absorbent and prone to decay over time while galvanized steel is more resistant to water, rust and corrosion.3.2. Longer lifespanWith wooden barns easily damaged by insects and birds, causing termites or nesting on the rafters. Steel buildings can limit these problems as well as avoid degradation due to burrowing insects.3.3. Fire ResistanceThe surface of PPGI is covered with special fireproof layers to help steel frame buildings have high fire resistance, slow down the spread of fire. Types of barns in foreign countries need to pay insurance levels in case of fire and explosion. Therefore, although wooden warehouses are lower in cost, in the long run, steel buildings have better insurance costs which helps to optimize overall costs.3.4. Strength and durabilityPPGI sheets are durable, withstand heavy loads but are lighter than many other building materials. The barns made from steel are 30-50% lighter than wood. This helps the construction of steel frames and building details save more time and manpower than traditional materials.4.

In the 8 months of 2023,Vietnam’s steel volume exported to the US has seen a significant increase, including main products such as galvanized steel and construction steel. In the face of challenging weak steel consumption demands, the increase in export production reflects the continuous efforts of the Vietnamese steel industry to improve product quality and establish its position in the international market.Recent overview of Vietnam's steel volume exported to the USAccording to statistics from the Customs Department, Vietnam's steel volume exported to the US tripled the amount of steel imported from the U.S in June 2023. This stands out as a special spot in the context of sluggish steel exports from the country in the first half of this year when the major markets like Europe and China are experiencing stagnation due to declining construction and real estate markets.In the steel export sector, the U.S. market continues to show great potential, accounting for 8% of Vietnam's steel exports in 2022, ranking fourth among Vietnam's steel export destinations alongside ASEAN, the EU, and China. In the first 7 months of 2023, according to the General Department of Customs, the U.S. market was among the top 3 largest importers of iron and steel from Vietnam, with a value of $386 million. As the U.S. begins to show signs of economic recovery, particularly in the reconstruction of factories and homes, Vietnamese steel enterprises have seized the opportunity to boost their export volume to this large market.The Vietnam's galvanized/galvalume (GI/GL) steel volume exportsIn the past 8 months of 2023, the export volume of galvanized (GI) steel to the U.S. exceeded 37,000 tons, generating a total value of over $36 million. Hoa Sen Group ranked as the top enterprise exporting GI steel products to the U.S. with nearly 10,000 tons. Besides Hoa Sen Group, Ton Đong A Group also showcased its exceptional strength in the U.S. market, exporting over 6,500 tons of GI steel in the past 8 months.The statistic about top Vietnamese galvanized exporters to the US in 8 months of 2023In addition to GI steel, the export volume of galvalume (GL) steel was also impressive, reaching 86,000 tons in the first 8 months of 2023 with a value of $89.6 million. Among the enterprises exporting GL steel, Ton Đong A Group stood out, exporting nearly 75,000 tons, capturing an 86% share of the overall market for GL steel exports to the U.S.The statistic about top Vietnamese galvalume exporters to the US in 8 months of 2023Galvanized steel products have long been a strength of Vietnamese steel mills, produced on modern steel coating lines that ensure uniform and high-quality coatings, meeting international standards including ASTM from the U.S. Thanks to ongoing technological investments in production, Vietnamese GI steel is gaining a strong foothold in major markets like the United States.The volume of Vietnam's PPGI/PPGL exportsThe export volume of galvanized steel products to the U.S. in the past 8 months exceeded 32,400 tons, with a total value of over $48 million. Ton Dong A Group led the way, exporting more than 13,200 tons, primarily in the form of pre-painted galvalume (PPGL). Other major steel exporters in this category included Nam Kim and Hoa Sen, with export volumes of 7,300 tons and 6,900 tons, respectively.The statistic about top Vietnamese PPGI/PPGL exporters to the US in 8 months of 2023The U.S. market demands strict quality standards for steel products, so successful Vietnam’s steel exports to the US require careful investment in the production process. Most large-scale steel mills in Vietnam, such as Hoa Sen, Ton Nam Kim, and Ton Đong A, have integrated coating technologies to ensure consistent coating quality, flatness control, and optimization.The volume of Vietnam's construction steel exportsThe export volume of construction steel to the US mainly includes two key products: rebar and wire rod. Among them, rebar had a total export volume of over 15,600 tons for the entire industry. Leading the way in steel exports were Hoa Phat Group, which supplied over 10,000 tons of steel to the U.S. in the first 8 months of 2023, capturing over 60% of the market share.The statistic about top Vietnamese construction steel exporters to the US in 8 months of 2023Trade activities in the steel sector between Vietnam and the US have consistently been positive despite trade investigations. The US remains one of the most important export markets for Vietnam's steel industry each year. The ramped-up Vietnam’s steel volume exported to the US have to some extent addressed the challenging issue of steel consumption needs for Vietnamese factories, aligning with the trend of diversifying investment activities in the country.

In construction, PPGI and PPGL are always on the list of the most popular materials because they help significantly improve building quality. Today, the functions of PPGI and PPGL have been constantly researched and developed by manufacturers of new types of building materials. A good example can be followed by taking advantage of PPGI/ PPGL in Sandwich Panel.Define about Sandwich Panel and its structure.Panel is the name of a popular building material in recent years. Panels are often used for roofing thanks to their thickness and sturdy structure, so they possess excellent heat resistance and sound insulation features.A panel will usually have 3 layers of texture, and the top 3 layers will be bonded together by specialized glue:Outer layer: the outermost layer of the panel is usually composed of pre-painted galvanized or pre-painted galvalume steel. The manufacturer often applies an electrostatic coating layer to increase the roof's aesthetics based on customers' color requirements.Middle layer: the middle layer of the panel is shaped like a thick foam, and the primary use of the middle level is to improve sound resistance and heat insulation. Some common materials to make up the middle layer of the panel can be mentioned as PU, EPS, glass wool, mineral wool...Inner layer: the innermost layer has the same structure as the outermost layer, but manufacturers often skip the color coating step because the innermost layer is considered a hidden layer of the panel, so painting will not be necessary.Some benefits of PPGI/ PPGL in Sandwich PanelSound insulation and heat resistanceA panel's most prominent advantage to the construction project is the ability to sound and heat insulation. Thanks to the acquired 3-layer structure and the foam middle core with a soundproofing effect, the panel will be highly suitable for construction installation in urban areas where there is always noisy pollution.In addition to the good soundproof foam core, the surface layer of the is also equipped with a layer of PPGI/PPGL in Sandwich Panel - a material that is famous for its thermal insulation thanks to its ability to reflect heat from the sun, thereby bringing a relaxed and comfortable working space for users.Fire protectionSteel is essentially a material formed through heat treatment at high temperatures, so steel will not conduct fire. Especially with galvanized steel, the fire situation will be significantly reduced due to zinc layers. The panel with 3 constitutional layers is likened to a fireproof wall because it can survive in an environment that is up to 1000 degrees Celsius. Even in the combusted case, the fire that burns into the steel for a long time only causes the steel to shrink and fade, but not cause the steel to spread fire.Eye-catching colorsTo meet more requirements in construction design, manufacturers are increasingly investing in coating technology along with outstanding color gamut. One of the most common applications is using PPGI/PPGL in Sandwich Panel. Because these are locations installed outside, it is always required to ensure aesthetic quality.Durable and anti-oxidationIf the panel only has a porous layer, it is easily corroded and negatively affected by external factors such as environmental humidity or oxidizing agents. Adding the coated layers on both sides will significantly extend the panel's life up to 50 years.The galvanizing/galvalume layer is not only anti-corrosion, but it also helps the surface of the panel always maintain a bright and new outlook because the zinc-aluminum in PPGI/PPGL has a significant effect on anti-scratch for Sandwich Panel. It can be said that thanks to the combination of PPGI/PPGL and foam core, the panel not only meets the durability standards in structure but also brings sustainable beauty over time.How to choose quality PPGI/PPGL in Sandwich PanelPanels have many types, and each type has its own thickness and unique function, the price when buying the product is also partly affected by each panel type. Finding out and classifying prices will be even more difficult if you are an importer because the price depends a lot on the thickness of the surface corrugated board, the size of the width, the length, etc. Choosing a professional steel solution consultant will be wise for your trading strategy.MRS Steel is currently a partner of many large steel manufacturers in Vietnam, such as Hoa Phat Group, Pomina, and Ton Dong A,...thanks to our close relationship with the factories that will help you access various sources with many different types of steel. Based on our long-term experience and understanding of the steel industry in the Vietnamese market, we are confident that we will be your long-term supporter in solving imported problems, thereby helping you to adjust the plan in time to optimize costs while still receiving quality goods.

Pre-painted Galvanized, also known as pre-coated steel, coil-coated steel, and color steel, is widely used in construction, such as round pipe production, square tube, factory manufacturing, automobile equipment manufacturing, household appliances, civil engineering,... In particular, the world also utilized PPGI for cold room and refrigerated transportation. Let’s get deeper into the outstanding features of PPGI with MRS Steel.1. What is PPGI? Pre-painted Galvanized (PPGI) is a type of galvanized steel coil that is surface treated and coated with a high-grade color layer, acting as a protective and strengthening layer.  Similar to zinc/aluminum alloy or zinc/aluminum/magnesium alloy coated coil products, color-coated corrugated sheet is also produced by hot dipped metallic coated technique.Hot-dip continuous galvalume/ galvanizing (CGL) produces all kinds of zinc-aluminum and zinc-plated steel. First, an annealing furnace is used to change the mechanical properties of surface-treated cold-rolled steel in accordance with order requirements and improve adhesion to the plating layer. The steel tape is then coated with a protective layer (anti-finger, oil, chromium) by the hot-dip galvanizing principle to increase durability and prevent surface oxidation.2. PPGI used for cold room and refrigerated transport2.1. Cold room applicationA cold room is designed and installed with a cooling or freezing system for the purpose of preserving and storing goods to keep the best quality. The particular structure of cold storage is heat and sound insulation to keep the temperature in the warehouse lower than room temperature. Cold storage is classified according to many uses or different types of goods, but all have the same structure of two parts: insulation and refrigeration. Two panels commonly used as cold storage covers are EPS Panels and PU Panels. Panel Polyurethane Sandwich is a high-grade material consisting of 3 layers of polyurethane foam sandwiched between two metal side skins. This material is highly durable, lightweight, and resistant to extreme weather conditions, so it is genuinely appropriate for cold room applications:Polyurethane Sandwich Panel is easy to assemble, transport and dismantle, suitable for mobile cold storage.The outer and inner shell of the PU Panel is made of galvanized steel with a plastic coating, and the panels are bonded together by a quick-action eccentric device.The panels are capable of bearing loads up to 2000 kg/m2Cold storage fully equipped with electric lighting system, refrigerant Freon 22 and 404A. 2.2. Refrigerated transport applicationRefrigerated Freight Transportation is a particular industry in today’s globalized world, with constant temperature control, enabling the goods to remain at the desired temperature throughout their journey.The basic idea behind cold transport, which uses salt and ice to keep temperature-sensitive goods cool, dates back to the 1800s. Currently, refrigerated transport vehicles are usually made from Polyurethane Sandwich Panels. PU panels can improve storage efficiency, reduce fuel consumption, and reduce the vehicle's overall weight due to their durability and lightweight. The bodywork is comprised of PPGI sandwich boards with a thickness of 50mm for freight and 100mm for refrigerated vans/trucks.Besides PU Panels, mild steel is manufactured to specialized specifications to make refrigerated truck bed floors. The structure of mild steel contains about 0.05 - 0.3% carbon, so it is very malleable and ductile as required. When mild steel plates are galvanized, they will have an additional layer of protection against rust, oxidation, high strength, and good heat retention.All refrigerated trucks are equipped with the best refrigeration units - DANA WATER HEATERS & COOLERS. The temperature monitoring system in the driver's cab can easily adjust the proper temperature. 3. Vietnam's production capacity of color-coated galvanized steelAccording to a report by the Vietnam Steel Association, coil, galvanized steel, and PPGI are the most exported steel products in 2022, with galvanized steel exports reaching 1.4 million tons, equivalent to 1.5 billion USD.Vietnam's galvanized/aluminum/color steel products are aimed at exporting to world markets such as Europe, the United States, ASEAN,..., so they must meet the following standards: JIS 3321: 2010 of Japan; BS EN 10346: 2009 of Europe; AS 1397:2001; ASTM A792 of the United States… Zinc-aluminum alloy plating/galvanizing lines are imported from leading corporations specializing in metallurgical and steel-rolling equipment, such as Danieli, Tenova, and G7 countries with the best-advanced technology.For details on importing PPGI used for cold rooms and refrigerated transport from Vietnam, please contact MRS Steel via Email: vanloc@mrssteel.com.vn

Vietnam's pre-painted galvalume/galvanized steel production line follows the most advanced technology from Danieli and Tenova metallurgical and steel-rolling corporations, so it produces products with high durability, good resistance to corrosion and rust, and many beautiful designs and patterns. Below are the Top 10 Applications of Pre-painted Galvanized/ Galvalume (PPGI/ PPGL) in practice.1. Roofing and Cladding (Single Skin)Roofing and cladding are the most apparent application of PPGI/PPGL in the construction sector. The roof sheets are usually corrugated iron with 6 waves, 9 waves, 11 waves, 13 waves, etc. have an edge that bricks and tiles about lighter, reducing the load on the frame, columns, and foundation.PPGI/PPGL is also the main material for coating and protecting building surfaces. Aluminum cladding are 1/3 of the weight of steel, but still ensure the stability and sustainability of the project. PPGI has perfect anti-rust and anti-corrosion ability in the long run, so it is more and more preferred as a protective panel for all constructions.2. Sandwich Panel (Double Skin)Panel Polyurethane Sandwich (Panel PU) is a high-strength material composed of 3 layers of polyurethane foam surrounded by outer layers of galvanized/aluminum/color steel. PU panel has high strength, good insulation ability, extremely light in weight but high load-carrying capacity. They are used to cover cold storage, roof, interior or exterior walls of buildings.3. Rolling doorsRolling door system is composed of many main parts such as controller, motor, door and other parts depending on the design. Rolling door profiles and bodies are all made of PPGI/PPGL, a material that is light, durable and resistant. Because of this, pre-painted galvalume/galvanized is suitable for exterior use with high life expectancy.4. Agricultural equipment, greenhouses, silos, barnsPPGI/PPGL has a smooth surface, good rust resistance, variety of sizes, easy to shape that is frequently used in irrigation systems. For the animal husbandry, large galvalume or galvanized pipes are used to make feed or waste pipes for livestock and poultry.Greenhouse projects also use PPGI pipes because of the outer and inner surfaces laminated with polyester color paint. In addition, the zinc coating also helps the product to withstand harsh weather conditions well, without affecting the building structure.5. Ceiling AccessoriesCeiling accessories are fireproof, corrosion resistant, thermally stable and weather resistant thanks to their color coated galvanized steel. Because of their light weight, durability, high load-carrying capacity and no change to the overall structure of the building, ceiling accessories are used as decorations for many industrial and civil buildings.6. PartitionsNowadays, partitions have developed into many different types such as fixed partitions, movable partitions, waterproof partitions, glass partitions or partitions made from PPGI, PPGL,…7. Vehicle manufacturing industryPPGI/PPGL is used for manufacturing car doors, beams, wiper blades, trunk lids, oil filters, oil sumps,... Galvanized is also specialized for car and train parts as a base coat for body panels. In the transport industry, the bodywork of caravans and recreational vehicles also uses PPGI because of its high-quality, multi-color coating, which meets the customer's requirements.8. Home appliance industryPPGI has rich colors, smooth surface and high aesthetics, so it is widely used for roofing, windows, doors, interior decoration or household appliances. The front PPGI panel has a polymer linear non-thick polyester resin coating and the back side uses a modified epoxy paint suitable for the surface or cover of refrigerators, washing machines, DVD player housings, air conditioners, Led TVs, microwave ovens,…9. Steel furniturePre-painted steel is widely used to build furniture thanks to high-quality, cost-effective three-dimensional design. Steel furniture products are manufactured by nano-environmental technology, so they are safe for consumers' health, have a long life expectancy. In particular, PPGI is gradually replacing wood and marble to make insulating walls with aesthetics and performance that are not inferior. Some other significant applications of PPGI in the real estate industry include:WardrobeLockersTableBookshelfBed 10. Cold Room, Shelves, Water Chiller, Water Cooler, Water Heater & HVAC EquipmentThe structure of cold rooms or cooling systems is heat and sound insulation to keep the temperature inside lower than outside. PU panels made from color coated galvanized steel are the main materials for the production of various types of cold rooms, Shelves, Water Chillers, Water Coolers, Water Heaters & HVAC Equipments.Above are the top 10 applications for PPGI/PPGI , widely used in many fields of life.
