Today's metal roofing sheets become essential to building protection and are applied in many fields. Standing seam roofing is currently one of the outstanding solutions with absolute ant-leak function for the building, thanks to its unique design. In this article, let's learn and take a closer look at the standing seam roofing with MRS Steel as well as the advantages it brings to the contractor.1. Overview and Features of standing seam roofingStanding seam roofing is a form of metal roofing with a wavy shape through the method of rolling. However, standing seam roofing has a slight difference in that the edge line will be designed according to the joint molds. Instead of the roof panels being connected together by screws traditionally, they will now be connected by a row of hidden clips located at the edge.Similar to other types of metal roofing on the market today, standing seam roofing is made up of galvanized or galvalume steel, and then the manufacturer will cover it with a layer of paint to enhance the durability of the product.MaterialPre-painted GalvanizedPre-painted GalvalumeBase materialCold rolled coilCold rolled coilYield strength240MPA340MPAStandardsASTM A653/A653M, ASTM A755/A755M IS 277/IS 513, IS 14246 JIS 3312ASTM A792/A792/ASATM A755/A755MJIS 3312Coating coverageAS 1397AS 1397Coating massZ120 g/m(gsm)AZM 150 g/m(gsm)Coating thicknessMinimum 18-20 micronsMinimum 18-20 micronsColorAccording to a color chartAccording to a color chart2. Advantages and widespread applications of standing seam roofingThe line of standing seam roofing is currently one of the widely used corrugated iron products in life and industry. You can easily see the presence of standing seam roofing in residential construction applications, livestock barns as roofs for factories, etc. Businesses choose to use it because it brings significant benefits such as:Increase the appearance of the building: thanks to the locking structure between the layers of corrugated iron, the corrugated steel sheet now no longer has the appearance of screws. This helps the corrugated steel surface become aesthetic and smooth.Perfect anti-leakage: With the feature of not using screws to fix as traditional, the corrugated iron surface will not have holes, thereby minimizing water leakage when it rains.Optimal installation length: the standing seam roofing is a combination of a series of corrugated iron roofing sheets through joint clamps, so manufacturers can rely on that to extend the length for demand. The length that a standing roofing system can achieve for a building can be up to 100m.Durability: The galvanizing and galvalume methods allow the roofing sheet to be equipped with anti-oxidation and corrosion resistance, good heat resistance, and highly suitable for outdoor installation. 3.

On the market today, steel coil is a commonly used type with many different types. However, many people still do not distinguish between the types of steel coils and their uses. Let's find out more about MRS Steel in the following article.1. What is a steel coil? The steel coil is a steel type that is quite commonly used today. This type of steel is produced with a smooth or ribbed surface that is curled together. Making quality steel coils requires a complex steel production process that requires high technical and technological qualifications. Depending on the needs and purposes of use, there will be different types of steel coils.2. Application and classification of steel coil 2.1 Hot rolled coil Hot-rolled coil is the finished product of the process of smelting, casting billets, and hot rolling at a temperature of 10000 °C. This steel is the raw material for creating cold-rolled coil, welded steel tubes, and cast steel pipe. Normally, a hot-rolled coil will have a blue-black color and a rough surface that is less aesthetic.Hot-rolled coils are commonly used in the automobile industry, railways, shipbuilding, roofing corrugated iron, the production of H- and I-shaped steel beams, moving floors, ladders,...2.2. Cold rolled coil The cold-rolled coil is a hot-rolled coil after cooling and re-rolling at room temperature to produce cold-rolled coil products with the desired shape and size. This process will not change the structure of the steel, but only the shape of the steel in accordance with the needs and purposes. However, if the cold rolling process is not strictly controlled, it will deform the product. The cold-rolled coil has a smooth surface, so it ensures higher aesthetics and durability.Cold-rolled coils are often used to make flat sheet products such as steel plates, coils, laminates, round and square details,.. and products with smooth surfaces. 2.3. Galvanized steel coilThe galvanized steel coil is a cold-rolled coil that is additionally plated with a layer of zinc on the outside of the surface. This is one of the most influential and economical methods of protecting steel from corrosion under the influence of the environment.Galvanized steel coils are widely used in building architecture, roofing, ventilation systems, solar water heaters, televisions, refrigerators, the automobile manufacturing industry, the manufacturing industry,...2.4. Stainless steel coilStainless steel is a steel alloy with a minimum chromium content of 10.5%, which is a standard metal in Vietnam and is commonly known as stainless steel. Manufacturers often choose to use stainless steel as a metal production material because it has good corrosion resistance, oxidation resistance, high strength, and does not stain or rust. Stainless steel is commonly used in many industries and construction projects, such as aerospace, architecture, medical, home appliances, and jewelry...2.5. Pre-painted steel coilPre-painted steel coil, also known as color-coated corrugated iron, is a type of corrugated iron made of galvanized steel coated with a layer of color paint to increase the aesthetics and longevity of the building. Pre-painted steel coil has high strength, good bearing capacity, corrosion and rust resistance, and many different designs and shapes suitable for each type of construction.Pre-painted steel coils are used to make roofing sheets, rolling doors, interior decoration,... In addition, it is also used to make industrial electrical products, household appliances, insulation systems,...3. Reputable coil supplier in Vietnam Buying coils becomes more manageable when many enterprises produce and trade coils in Vietnam.

Strip steel is one of the most versatile forms to be fabricated and handled from the coil. It is used in most industries, including construction, automobile manufacturing, and a number of essential applications in scientific and medical engineering. In this article, MRS Steel will help you better understand “what is strip steel” and production technology and distinguish it from other common steel variations.1. What is strip steel?Strip steel is a bulk steel material used to manufacture small steel components. Companies often buy this material in large coils, then cut and process it to create more petite strips. It is less than 24 inches (60.96 cm) in width, in thickness between 0.157 - 0.197 inches (4 - 5 mm). The strip steel is the most suitable choice for projects requiring small plates or steel pieces.2. Strip steel production processTo make strip steel, mills start smelting iron ore at a high temperature of 20000C and combine it with other chemical components and metals to create the desired alloy. The steel in the furnace is molten into a cold die, which thins and hardens the shell.The next step is to shape the steel according to its intended use. The hot rolling process will help thin the steel, create flat, long, round, seamless, striped,.., and remove surface defects.Next, the steel can be subjected to a technical treatment such as acid pickling, removing impurities, coating the outer surface, heat treatment, anti-oxidation surface treatment,... This process will help the finished products to have higher quality and improve the required properties.Finally, the large coils undergo a processing called roll slitting, which cuts the steel into smaller strips.3. Outstanding properties of strip steelStrip steel is a product made from hot-rolled or cold-rolled coils, so it possesses many advantages of these steels. For example, strip steel is made from the hot-rolled coil that has been pickled, rolled, and treated with impurities on the surface, so it has a high finish and tighter thickness tolerance than the cold-rolled coil.Strip steel is lightweight and easy to process, transport, and assemble, so it is suitable to replace some large steel plates in projects requiring small details and parts.4. Application of strip steel in lifeCustomers can select from a wide range of strip options to meet the requirements of specific constructions and applications. Hot rolled strip steel has a lower price, but the surface texture is rough, and the aesthetics are not high. On the other hand, cold rolled strip steel has a smooth, shiny surface, so it costs more. Manufacturers use strip steel in many projects such as auto parts manufacturing, home appliances, construction works, and electronic components,...Automotive Industry: Cold-rolled stainless strips are used to make various automotive parts. The strips are stamped and cold rolled into the required shapes and sizes, so they are easy to assemble and construct.Construction works: Stainless steel products are popular construction materials with high applicability and easy fabrication. The rolling and casting technologies create high-quality steel strips that meet the structural and technical requirements of the building or construction.Electronic components: Stainless steel strips have favorable thermodynamic properties in terms of heat conduction, heat capacity, and melting temperature, so it is used to make electronic components used in refrigerators, air conditioners,... 5. Differentiate between sheet and strip steel productsAluminum alloys and stainless steels are available in wide variations, including sheet steel and strip steel. You can classify these two types of products by the following identifying features:Aluminum and stainless steel sheetThe sheet is one of the most popular metal variants, less than ¼ inch thick, made by rolling steel to the desired thickness. The finished stainless steel sheet is also pickled in an acidic solution, coated with a thin layer of oil to protect the surface.Stainless steel typically undergoes a rigorous annealing, heat treatment, and hardening process to increase ductility and resistance to corrosion. The edges of the coil can be chopped to create the desired width, such as 42”, 60”, 72”, or cut to standard lengths of 96”, 120”, or 144”.Aluminum and stainless steel stripBoth sheets and strips are sourced from flat-rolled steel. Similar to how aluminum sheets are produced, stainless steel strips are also laminated from the coil. The most significant difference between these two variants is in the size. Any coil product with 24” or more dimensions is considered a sheet, and less than 24” is considered a strip.To produce strip steel, coils are processed through a roll-slitting process that can produce widths as small as 0.035”6. Vietnam – The world's leading source of high-quality, prestigious steelAccording to the Industry and Trade Information Center 2021 report, the total production of steel of all kinds in Vietnam reached 33.2 million tons, up 28.2% compared to 2020. In construction steel reached 12,317,765 million tons, hot rolled steel (HRC) reached 7,122,601 million tons and cold rolled steel (CRC) reached 5,283,461 million tons.Vietnam's steel exports in 2021 also increased by 32.9% in volume, reaching 13.1 million tons, and 124.3% in value, reaching 11.8 billion USD compared to 2020. Vietnam is currently a significant source of steel for many countries and territories around the world such as ASEAN, China, the EU, the United States, Taiwan, the UK, Korea,...Thanks to an abundant steel source, meeting international standards, and the advantages of a 0% anti-dumping duty rate, Vietnam is the world's first choice for significant steel importers. If you are interested in learning about the situation of VietNam's domestic steel market, please get in touch with MRS Steel via Email at vanloc@mrssteel.com.vn for advice and detailed quotation. 

What is CO/MTC? You have heard a lot about CO and MTC in contracts for the sale of goods, but do you really understand these two types of certification? This article by MRS Steel will help you better understand CO/MTC and its effects on commodity trading.1. What is CO/MTC?CO (Certificate of Origin) is a certificate of origin indicating the origin of goods produced in a particular territory or country. Therefore, the purpose of CO is to prove that goods have an explicit and lawful origin in terms of tariffs and other law provisions on import and export.MTC (Mill Test Certificate) is a factory test certificate or factory test report issued by a manufacturer to certify a product's chemical and mechanical properties of a product and its compliance with standards and regulations, and current specifications.The ownership of CO/MTC is a very important and popular certification in the steel industry. Thanks to them, customers can prove the product's origin, which country standard the product is manufactured under, and whether the products conform to the standard so they can make the right choices for their projects.2. The role of CO/MTC2.1. CO (Certificate of Origin)The most crucial role of the CO is to certify the origin of the goods. This can help the manufacturer prove the product has a clear origin.Trade statistics and maintaining quota systems: Once the origin is established, it will be easier to make trade statistics for a country so that the trading agency can maintain statistics on import and export quotas. goods importAnti-dumping duties and subsidies will become more feasible if the product's origin is known. This lets the importer know whether the goods are entitled to special incentives.2.2. MTC (Mill Test Certificate)One of the most critical roles of the MTC is to demonstrate that products conform to published standards. The MTC is a quality assurance document sent from factories to their customers. These certificates describe the product's alloy, temperature, thickness, width, finish, and, more importantly, whether the metal product complies with international standards. Most MTC certifications must conform to the EN 10204 standard.Mill Test Certificate issued by manufacturer Ton Dong A3. Why does the steel business need a CO/MTC?CO/MTC is very necessary for each business unit; it is not only a condition for enterprises to export steel to foreign countries, but it is also proof to prove that steel products meet and meet quality standards.- Create trust for customers: The fact that a steel business enterprise has full CO/MTC documents will ensure product quality regulations, prove that it is not a fake, and prove that the unit is not a fake. The manufacturer is responsible for the quality of such goods.- It is a necessary condition to export steel: To export steel to other regions, it is necessary to first have sufficient certifications to decide whether the goods are qualified for import and export.- Enjoy special preferences: CO/MTC will determine the origin of goods, from which preferential tax will be applied where that country has joined pre-agreed trade agreements. It is also a document for the application of subsidies and anti-dumping laws. CO certification as a basis for planning how anti-dumping and countervailing laws are enforced.4. Vietnamese steel is fully certified for CO/MTCSteel products originating from Vietnam all have full CO/MTC certification. The fact that all Vietnamese products have CO and MTC helps Vietnamese steel gain a foothold in the world steel market. Vietnam is always committed to bringing high-quality steel products with the desire to bring sustainability to your work.In order to receive CO/MTC certification, Vietnamese steel enterprises always focus on investing in modern machinery and equipment lines, regularly upgrading and improving the system. CO/MTC is a standard measure for products with the same design and function from competing manufacturers in the market. Based on this, consumers can compare and choose according to their needs.
