Vietnam's steel industry has made remarkable developments in both production scale and technological lines. Vietnam steel quality has gradually reached important markets such as Europe and America. Today MRS Steel will make an overview of Vietnam quality steel as well as learn about breakthroughs in the country's steel production technology.Vietnam steel quality based on breakthroughs in steel refining technologyPreviously in Vietnam, most steel was produced through electric arc furnace (EAF) technology, but the EAF method was assessed to cause high electricity consumption. In addition, input materials such as iron ore or scrap steel contain too many impurities, which has generated more dust and large slag in the production process, reducing the furnace's life span and affecting the quality of the output steel.In the period from 2010 to 2020, many domestic steel enterprises have installed blast furnaces with large capacity, specifically Hoa Phat has operated 2 blast furnaces with the capacity is 1,350 m3, Formosa Ha Tinh has installed blast furnace No. 1 with a capacity of 4,350m3 and blast furnace No.2 with a capacity of 4,350m3. The improvement of furnace capacity has helped manufacturers minimize dust emissions, eliminate harmful impurities and reuse energy through coal gas recovery to produce thermal energy for the furnace.In addition, the large manufacturers such as Hoa Phat, Formosa or VN Steel,... have installed the technology of basic oxygen furnace (BOF) or the LD converter into manufacturing activities. In particular, the technology of BOF has a significant effect in burning all impurities in liquid iron and the steel scrap. Specifically, Hoa Phat's output steel has the percentages of impurities (Cu, Ni, Cr). ) is very low when less than 0.03% and this figure is lower than the standards of many countries in the world. Based on an extremely low impurity rate, the output steel product will achieve purity and consensus in quality, the steel will have good bending properties, combined with toughness and high yield strength will improve the sustainability of construction.Continuous investment in steel production linesDuring the past 10 years, the domestic steel manufacturers have continuously invested in steel refining technology as well as improved modern techniques in production lines in order to bring more Vietnam steel quality to the abroad markets. Currently, most steel producers in Vietnam such as Hoa Phat, Hoa Sen, Ton Dong A, Nghi Son, ... all use the most advanced steel production lines in the world such as Danieli - Tenova from Italy,  SMS from Germany,...Most of the galvanizing or color coating lines in Vietnam are equipped with gas recovery systems to help manufacturers save energy. Another highlight of these technologies from Europe is low operating costs as well as high flexibility when it can be applied to many types of steel products as well as can accept many different coating materials.For example, the CM4 color coating line of Ton Dong A is equipped with an RTO gas recovery system to help protect the environment or Hoa Sen Group's galvanizing line is equipped with an electric annealing furnace to help reduce waste of gas emissions from the factory. In addition, the color coating lines are also equipped with NOF annealing furnace technology to help the galvanized layers adhere to the steel better, assisting manufacturers to control the exact thickness of the layers, optimally treating temperature of flatness and gloss of the finished product.International standards for output productsCurrently, Vietnam steel quality products have reached many countries around the world including large markets such as Europe, America, Australia, etc. The equipping of advanced production lines has helped domestic steel manufacturers qualify to produce quality steel grades in terms of size, weight, ductility, and bearing capacity. Before being exported, steel products are fully certified standards including JIS of Japan, ASTM of America, BN of UK, AS of Australia.Besides, the quality management system standards at factories are also an important factor to evaluate the quality of output products. Most of the domestic steel factories come from corporations such as Hoa Phat, Hoa Sen, Ton Nam Kim, Ton Dong A, Vn Steel,... all obtained the certification of the latest standard ISO 9001:2015, which partly shows the production capacity and resources of the enterprise.Finding the reputable supplier of Vietnam steel qualityVietnam's steel industry in recent years has made amazing changes as it has gradually become self-production with a wide range of steel products.

The trend of using steel in the warehouse industry is becoming increasingly popular, ranging from constructing warehouse structures, canopies, to storage racks. In the warehouse industry, factors such as efficiency, durability, and cost-effectiveness play a crucial role, and steel is the material that can comprehensively meet these criteria, as outlined in the reasons in the following article.The durability of structures are enhanced through steel in the warehouse One of the reasons why steel is increasingly preferred and widely used in the warehouse industry is its durability and its ability to provide structural integrity. Especially in storage racks, a robust frame system is essential to support the load when storing a large quantity of goods for an extended period. Racks need a certain level of rigidity to avoid bending or deformation under the weight of the goods, and high-strength steel types contribute to ensuring the required stiffness and stability of the racks.The warehouse industry always demands long-term storage, where durability is crucial in facing the challenges of time. In regions with high humidity, fog, or near the sea, steel may encounter challenges from salt and oxidation. However, manufacturers can address this issue by applying additional layers of zinc coating to protect the steel surface and enhance the lifespan of storage structures.Flexibility in design helps expand storage space for goodsSteel with a certain level of flexibility brings about versatility in shaping and designing. Specifically, steel can be easily processed and designed in various sizes and shapes. This enables manufacturers to construct multi-tiered racks that are tall and vaulted without compromising stability. Additionally, the ability to extend the length across spans helps optimize the storage space for goods.Modern warehouses are typically categorized based on various storage needs, such as cold storage or distribution centers. Thanks to the ability to be processed in various forms, steel racks can meet diverse design requirements, for instance, catering to the low-temperature storage needs of cold storage facilities or optimizing storage space for distribution centers. Importantly, steel rack systems offer an open space within the warehouse, enhancing integration with automation systems, robots, and other smart devices to optimize the transportation, handling, and storage processes for goods.Using steel in warehouses helps save installation and regular maintenance costsIn the warehouse industry, cost-effectiveness is considered a paramount factor, and steel is an extremely suitable material for cost-saving solutions during both installation and regular maintenance. Typically, steel components are manufactured and shaped according to customer requirements in the factory. They are then transported directly to the delivery location, and the warehouse section only needs to arrange suitable installation locations. Utilizing pre-prepared components helps minimize installation time, allowing warehouse management to reduce labor costs and expedite project completion, enabling the warehouse to start operations sooner.In addition to its rigidity, one of the primary characteristics of steel is its excellent corrosion resistance, especially in the case of galvanized or stainless steel. Although the initial cost of installing steel components is considerably higher than that of other materials, the durability that steel provides helps management significantly save on fixed costs. The good corrosion resistance implies a reduced likelihood of deterioration, leading to a decrease in annual maintenance costs and limiting the frequency of repairs or replacements for components.Ensuring safety through fire resistanceWarehouses are crucial for storing goods, making safety within these spaces of utmost importance. Specifically, the ability to resist fire and moisture becomes a crucial factor in ensuring the safety of stored goods. Unlike some other building materials, steel is fire-resistant and non-combustible. The metallic nature of steel helps prevent water from infiltrating the structure, providing an effective defense against moisture. The steel's impermeability reduces the risks of damage caused by water, protecting goods from mold or decay due to dampness.Even in the event of a fire or explosion, steel maintains the integrity of the structure better than other materials, even when exposed to high temperatures. This is critical in emergency situations, as steel can withstand temperatures up to 1000 degrees Celsius. The low flammability and high heat resistance allow warehouse managers additional time to respond to emergencies, prolong evacuation times, and limit potential damages.Using steel in warehouse components provides high load-bearing capacity, ensuring that storage racks can withstand significant weights without encountering undesirable deformations. The durability and safety of steel not only help maintain the structural integrity but also reduce maintenance costs and enhance corrosion resistance, making the warehouse system stable and sustainable over time. Through this article, we hope that viewers can gain a more objective perspective on the role and long-term potential of steel in the warehouse industry.If you are looking to import steel for your project and are unsure about choosing a reputable manufacturing plant to ensure quality, please contact MRS Steel for free assistance via email: vanloc@mrssteel.com.vn or Whatsapp: +84 76 911 2358.

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.
