The purpose of the steel mills assessment is to select the right supplier for the enterprise's requirements. That's important, but many businesses are still wondering what the objective and accurate evaluation criteria are. The following article summarizes the criteria for evaluating steel mills so that you can choose reliable partners.Reputation of steel millsWhen evaluating a steel mills, the reputation of the factory is the first factor and also a decisive factor in deciding whether to cooperate or not. To consider whether the factory is reputable enough, we need to note a few aspects:Clear information: Does the factory really exist? Address, contact method, business license or not?Transparency in cooperation: Does the factory ensure the supply of raw materials and maintain long-term cooperative relationships with partners?Review of legal issues: View legal procedures related to past and current factory contracts; Is the factory's legal compliance guaranteed?Product qualityThis is the most important criterion when any business wants to make a decision about choosing a steel mills. When sourcing products, businesses will proceed to provide criteria for quotes, product quality, materials, durability, aesthetics,... From there, make a detailed assessment and draw the conclusion that the product of this factory is suitable for the needs of the business you are looking for. You should build a form, a tracking sheet in the form of a scale, to comment on all aspects of the quality of goods supplied by the factory.In addition, it is also necessary to consider the damage rate of the goods. Specifying a specific risk level or criterion after the time of importing goods and conducting inventory, based on that ratio to track the quantity, find out if the cause of damaged goods is due to the transportation process or supplier error.Production capacity of steel millsProduction capacity is one of the important criteria for evaluating steel mills. The assessment of the production capacity of the factory will clarify the efficiency of the factory's production activities and its ability to meet the needs of the market. A factory with a large production capacity is equivalent to an abundant labor force and modern machinery and equipment. Besides, production capacity also helps to assess the potential of the mill development. The larger the steel mills production capacity, the larger the mill.Product delivery performanceIn the criteria for evaluating steel mills, it is indispensable to evaluate the factory's product performance. Ensuring the performance of the factory's product supply determines the business plan of the enterprise. Therefore, suppliers need to ensure credibility in the time and quantity of products provided. Below are the factors used to evaluate the product supply performance of steel mills:Order fulfillment time: The time from the beginning of order fulfillment to when the supplier delivers the goods to your business.Reliability of delivery: Ensure the agreed delivery time, sure delivery, the right type of goods, the right quality, and the quantity of goods according to the contract.Information: Information is exchanged throughout the steel mills and your business.Flexibility: The steel mill's ability to adapt its product supply to changing conditions.Production technology of steel millsCurrently, steel mills around the world use three main production technologies, including the basic oxygen furnace (BOF), the electric arc furnace (EAF), and the induction furnace (IF). In which BOF technology accounts for the majority, EAF and IF technologies account for a little and very little. This is also an important criterion that businesses need to pay attention to make objective and accurate assessments of steel mills.The fact that factories use modern production technologies not only brings high-quality products but also contributes to saving energy. Technological improvements and upgrades promise to be outstanding advances in product quality and output.Product price and payment methodProduct prices and payment methods are indispensable criteria in the steel mills evaluation criteria table. This criterion affects the buyer's ability to buy and profit. If there are two suppliers with the same quality and performance of products and services, the one with the cheaper price will bring more profits to the business. Evaluation factors may include:Competition: The price paid should be comparable to that of other competitors. Enterprises should have quotes from many steel mills for comparison and better evaluation.Accuracy and stability: The price on the order and on the invoice should only have a small difference. If there is a change in the price, the supplier should notify customers in advance. Prices also need to be stable over time.Payment transparency: The average time it takes to receive a credit note should be reasonable. The estimated cost should not change significantly from the final invoice. Supplier invoices should be timely and easy to read and understand.Customer serviceCustomer services help businesses in cases of problems such as product errors, missing orders, low-quality products,... Therefore, this is a criterion that cannot be ignored when proceeding with the steel mills assessment.When conducting supplier evaluation, it is necessary to collect opinions on the quality of support, the attitude of the supplier and response time to support requests, the qualifications of the support staff,... Customer service will be evaluated through three timelines: before the transaction, during the transaction, and after the transaction.Thus, the above article has summarized seven criteria for evaluating steel mills. However, to conduct the assessment according to the above seven criteria, enterprises need to have accurate, transparent, and complete information about the factory. I hope this information is useful for you in choosing a reputable and quality steel mills.

Construction steel is one of the largest steel-using industries, accounting for more than 50% of the world's steel demand. Steel is widely used in all constructions such as buildings, car-parks, schools, hospitals, skyscrapers,... According to a report by the United Nations, it is expected that the world population in 2050 will increase to 9.7 billion people, leading to a dizzying increase in the demand for construction works. In this article, we will learn more deeply about the role of steel in today's construction.1. What is Construction Steel?Construction steel is a type of steel used in the assembly and construction process, with many outstanding properties such as high strength, large load capacity, contributing to the solidity of the building.However, not all types of steel meet the requirements for application in the construction process. Steel must ensure the elements of hardness, strength, weldability and no warping. It is these properties that create the role of steel in construction that no other material can replace.2. What fields of steel are used?For buildingsStructural steel accounts for 25% of the steel used in buildings, creating a strong frame on site. Reinforcement bars add tensile strength and stiffness to concrete, which is the primary building material for deep foundations and basements.Steel sheet is also the main material of cladding products such as roofing, purlins, insulation panels,… Non-structural steels are also found in heating and cooling equipment applications and duct insulation products. In addition, rails, stairs, shelves,... are also made of steel.For infrastructureIn modern construction, steel is used mostly in projects of bridges and roads, airports, harbors, railway systems, fuel charging stations,... Rebar, sections and plates steel account for 60% of the steel used in these applications. High strength steel has the advantages of durability, heat resistance, fire resistance, good corrosion resistance and rust resistance, making it the main used steel in the pipeline systems of heat, oil, gas, ... in drilling rigs, offshore oil, thermal, nuclear and hydroelectric power plants.3. Importance of steel in constructionConstruction steel is most used to make pillar frames, solid foundations for construction works because of its high strength.Flexible applicabilitySteel is made from many metals that are combined together in certain proportions to determine the characteristics of the finished steel. Therefore, construction steel has many different designs, sizes and properties, so it can be applied flexibly in life, suitable for all project requirements.Ensure aestheticsToday, construction works not only require quality but also focus on external appearance. Steel is a material that can meet both of the above criteria thanks to a professional processing and shaping process such as rust removal, oil coating, zinc plating, high-grade color coating,..Cost savingsSteel accounts for about 23-33% of construction costs, with rough construction apartment buildings can range from 29-30%. Customers choose steel as the primary material in construction because of its availability, ease of access and optimal cost compared to many materials with similar properties. In addition, steel has durability, good weather resistance, so life expectancy is higher, so you do not need to regularly check and maintain it.Environmentally friendlyAs the demand for buildings and infrastructure continues to increase sharply because of the population explosion, reducing natural resource consumption and emissions is the most practical solution to protect the environment. Steel is a material with very good recyclability, easy to handle, remove impurities from scrap steel to create products with quality equivalent to steel produced from iron ore. Steel manufacturers are implementing environmentally friendly construction projects, saving weight and low carbon emissions.4. Contact to import genuine Vietnamese construction steelAccording to statistics of the World Steel Organization, Vietnam ranked 13th in the list of countries with the largest steel production in the world and 14th in steel export output with 11.2 million tons. The signing of the Free Trade Agreement between Vietnam and the EU and the Regional Comprehensive Economic Partnership (RCEP) has helped steel imported from Vietnam enjoy many incentives in terms of tax rates and anti-dumping duties.Thanks to closed-loop production technology from wire ore and advanced equipment systems imported from Tenova, Danieli and G7 groups, Vietnam's construction steel is always appreciated for its quality.

Besides aluminum-coated coils, galvanized steel coils are also widely used materials in many fields. Have you fully understood the characteristics, pros and cons of galvanized steel coils and how the galvanizing process takes place? 1. What is Galvanized Steel Coil?Galvanized steel coil is a material that is coated with an outer layer of zinc to protect the product from the effects of the surrounding environment such as temperature, humidity, air,... Thereby, limiting the possibility of rust , anti-oxidation and corrosion to increase strength and life span of coils.2. Methods of galvanizing steelCurrently, there are 3 most commonly used galvanizing methods: cold galvanizing, hot -dipping galvanizing and electro galvanizing.2.1. Cold galvanizing methodCold galvanizing is a method of coating a layer of liquid zinc on the surface of the product at room temperature and then putting it through a cold galvanizing process. Here, the mill uses compressed air to blow a liquid solution to form a beam of zinc particles that shoots onto the metal surface. In the solution, there are additives to help the coating adhere firmly to the metal surface and harden in a short time. Cold galvanizing technology helps to improve the corrosion resistance of metal, so it is the best solution for galvanizing metal materials on site.2.2 Hot dip galvanizing methodHot-dip galvanizing is the most popular coating technology today, capable of effectively protecting coils from the effects of the environment. This process starts from dipping the product into a molten solution to form a strong, non-flaking base and a smooth, highly aesthetic product surface.2.3. Electrolytic galvanizing methodElectrolytic galvanizing is a method of electrocoating that forms a thin layer of metal on the surface of coil for the purpose of preventing metal corrosion, increasing electrical conductivity, size and hardness. In fact, the electrolytic galvanizing method is used for steel products such as water pipes, railways, outdoor equipment, bearing equipment, machine parts,...3. Standard galvanizing processThere are 3 methods of galvanizing steel, but hot-dip galvanizing is still the most commonly used method in Vietnamese factories with the following standard implementation process:Step 1: Metal surface treatmentSteel made from iron ore or recycled steel also contains many impurities, dirt and oil that reduce the ability to adhere to the coating layer. Therefore, the material needs to be soaked in the degreasing solution for 10 - 15 minutes and transferred to a solution of hydrogen chloride concentration of 8 - 15% to remove rust.Step 2: Embed Soldering fluxAfter the steel is cleaned, it has dipped into the flux for about 3 - 20 seconds at normal temperature to completely remove the oxide and iron ions on the surface of the product. This is also the step that creates a coating that protects the steel from oxidation.Step 3: Hot dipped galvanizedSteel will be completely immersed in the galvanizing bath at the melting temperature (454 - 465 degrees Celsius) to create a layer of zinc coating on the surface. After completing the hot dipping process, performing slag scraping on the surface combined with vibration to remove excess zinc, the product will be coated with a layer of chromate to protect the surface comprehensively.Step 4: Cool down and check qualityIn order for the surface of the galvanized steel coil to be bright and beautiful, the product is cooled by an overflow bath. Experts observe and calculate the thickness of the coating by using specialized gauges to ensure that the finished product meets the specifications and requirements of the customer.4. Pros and cons of galvanized steel coilLow costThe production cost of galvanized steel coil is much lower than other surface protection coating methods, so it is the first choice for large-scale construction projects.DurableThe zinc coating protects the coil from rust, environmental corrosion and chemical reactions of the inner steel components. According to research, galvanized steel coil has high durability, using life up to 50 years in ideal conditions and from 20-25 years in harsh conditions such as industrial zones, coastal areas,...AestheticsCompared with conventional steel products, galvanized steel coils have a shiny, smooth surface and are easily coated with high-grade color paint to increase aesthetics.Reduce maintenance costsGalvanized steel products have high durability, long service life, so it does not cost a lot of maintenance and regular maintenance during use.5. Application of galvanized steelGalvanized steel possesses high strength, good bearing capacity, is a familiar material in popular applications including:Deck floor application to replace floor formworkVentilation ducts for apartments, high-rise buildings, shopping centers, factories, etc.Producing purlinProducing all kinds of steel pipes, water supply and drainage pipes, oil and gas pipelines, vehicle accessories,...Producing household appliances, furniture…6. Vietnam's export strength of galvanized steel coilWith investment in infrastructure, modern equipment and strictly selected raw materials, Vietnam galvanized steel coil mills provide product lines with thicknesses from 1.5 to 3.0mm, coating degree Z275 - Z350, strength up to G450.FDI projects especially favor these types of galvanized steel because of their durability. high quality and good resistance to environmental conditions, so the life of the works can be up to 50 years.In addition, galvanized steel coils also meet many international standards such as JIS G3302 of Japan, BS EN 10346 of Europe, AS 1397, ASTM A792 of the United States, conquering many difficult export markets such as the EU, the United States, Korea and Southeast Asia,...

Purlins are one of the materials that help support the structural framework, most often below the roof. Purlins carry the roof desk load and are supported by building walls, steel beams, rafters,... Purlins are an indispensable part of every project, so choosing the perfect purlin ensures the safety of the entire building. In this article, MRS Steel will share some tips for choosing the most suitable purlins to make the roof frame for the project.1. Choose the appropriate purlin materialPurlins combine with rafters to create a roof frame, combining the support of beam frames, walls or steel beams. When choosing the material of the purlin, importer can consider between black pipe steel, galvanized steel or high-strength steel. Each material has pros and cons in terms of strength and cost, so importers need to assess the building design to choose the most optimal material. However, to ensure the safety of the project, steel purlins must be able to withstand high loads, resist corrosion, rust and be unaffected by environmental factors.2. Choose the ideal type of purlinThis is one of the important factors when deciding which type of purlin for your project. C and Z shaped purlins are the two most popular types, have high applicability and unique characteristics as follows:C purlins are made from black or galvanized steel with a C shape and used in structural framework for factories, houses,... Importers can contact MRS Steel for advice on the most suitable dimensions, thickness and length for their specific application.Z purlins are manufactured from hot-rolled, cold-rolled, galvanized steel, shaped like the letter Z, so it is easy to stack and connect through bolted joints. Because of this characteristic, the Z shaped purlin has a higher thickness and durability than the C shaped purlin.3. Install purlins properlyCalculating the distance to install purlins compared to the corrugated iron roof in a reasonable, economical and safe way is important in choosing purlins for the project.Firstly, safety and sustainability are the top criteria, requiring the distance between purlins and corrugated iron roofs to be standard and reasonable. Next, if the purlins are not aligned or installed too far or too close, roofing will cost a lot of time and money. Finally, if the purlin distance is not suitable, it also reduces the building's load-bearing capacity, especially making it difficult to repair and maintain periodically.4. No weld/heat cutWelding or heat cutting methods are not used when installing purlins because high temperatures can affect the durability and strength of the purlins.5. Choose a reputable supplier and manufacturerPurlins are a key part in construction projects, so factories always produce many specifications to meet all customer needs. Importers can also find cheap sources from China, India,... but for some countries with strict regulations on C/O or trade defense measures, this option is not feasible. Meanwhile, Vietnam belongs to the group of countries with a developing economy, so it enjoys many preferential duty rates and import policies to the EU, United States, Australia, Mexico, Malaysia,...Vietnam has crude steel output ranked 13th on the world steel map and the largest in Southeast Asia, ensuring abundant and high-quality supply for customers. Many of Vietnam's largest factories do not receive orders directly from importers but through intermediary support units such as MRS Steel.MRS Steel provides solutions for importing Vietnamese steel to more than 30 countries around the world, with a network of links with many reputable steel factories and shipping lines to promote the fastest and most optimal delivery process.

Purlins are a specialized material used in frameworks and prefabricated houses to structural support and prevent rust and termites. Vietnam's increasingly developed manufacturing techniques have created many different types and standards of purlins. 1. What Is PurlinIn construction, a purlin is a horizontal bar or beam used in a roof support system. They are most commonly in buildings and are supported by the building’s rafters and its wall. Purlins are classified based on material and shape, serving different purposes. Purlins are very important in architecture and structure because without them, we cannot tile any other material on the roof.2. Types of Purlin in Steel BuildingC Shaped PurlinC shaped purlins are horizontal C-shaped bars that are light in weight, good strength and easy processing. The flat surface of the purlin is perforated to increase flexibility during assembly and construction. They are widely used in the construction of factories, houses, warehouses, shopping centers, airports,...Products commonly used for projects with column pitch <6m with common specifications are C200x50x1.8, C150x50x20x1.5,...Z Shaped PurlinZ shaped purlins are made with oval holes to easily connect the purlins together with bolts. This type is lightweight, easy to process and has better bearing capacity than C-shaped purlins. They are mainly used in projects with large areas such as factories, cold storages, commercial centers,... The most popular specifications are Z200x72x78x2.0, Z200x62x68x1.8,...Black Steel PurlinBlack steel purlins are made from hot-rolled black steel, known for its lightness, durable, heat-resistant, environmentally friendly and less deformed under strong impacts. However, black steel purlins are less widely used, especially in high-end projects because of their low aesthetic factor, low roughness and easy rust.Galvanized purlinsGalvanized purlins are black steel purlins covered with a layer of zinc plating to protect the surface. This enhances their durability, resistant to force and temperature and are especially resistant to rust and corrosion under weather conditions. High strength purlinHigh-strength purlins are manufactured by modern technology with higher quality than conventional purlins. The product has the ability to withstand high temperatures, the yield limit reaches a minimum of 350 MPa ~ 4500kg/cm2, light weight, large spans while still ensuring deflection within the standard range.3. What Purpose Do Purlins Serve In Construction?Purlins are divided into two types: roof purlins and regular purlins. In the prefabricated steel structures, builders often connect the purlins with round or V-shaped bars to firmly stabilize the purlin system.For columns of large factories with heights of 9-12m, purlins are supported by V-shaped struts to enhance the bearing capacity of the works. In addition to the role of bearing the roof load and human load, purlins are calculated and designed to bear the hanging load of wind ceilings, duct systems, electricity or decorative furniture.4. Where To Import Reputable And Quality Purlins From Vietnam?Steel purlins are one of the highly applicable products but not all purlins from every factory meet the required standards. In particular, some countries attach great importance to the issue of C/O when importing, so purlins must prove the origin of input materials.Vietnam is a country with crude steel output ranked 13th globally, advanced production technology, imported machinery systems from the most famous metallurgical brands such as Danieli, Tenova,... This has created the quality of Vietnamese steel, making Vietnam the largest steel industry in Southeast Asia.Under the escalating world economic and political situation, finding a reputable, quality steel supply source that is not in the group of embargoed countries is difficult for importers. Understanding these things, MRS Steel is a unit specializing in providing solutions to support the import of Vietnamese steel to more than 30 countries around the world.
