Stainless steel is one of the most popular materials in construction and civil manufacturing fields. Because of its durability and higher aesthetic properties compared to most other materials, the stainless steel production process is also quite complicated.History of stainless steelStainless steel is closely associated with the name of a British steel industry expert - Harry Brearley. He invented a special type of steel that has strong resistance to corrosion and rust by adjusting the Carbon and Chromium content appropriately.During the production process, Harry Brearley researched and added 8% Ni and 18% Chromium, successfully creating the 304 stainless steel grade that is very popular today. Because of its outstanding strength, stainless steel is widely used in many industrial and civil sectors.Understanding the stainless steel production processThe preparation of raw materials is the first factor that determines the success of the stainless steel production process. The elements iron, chromium, carbon, manganese,... are processed to remove impurities, ready for the next steps.Melting and castingSteel and alloy metals are added to an electric arc furnace and melted at temperatures above 2800 degrees F for continuously 8 -12 hours so that the metal completely turns into liquid. During the melting process, experts must regularly check the temperature and chemical composition so that the finished products are as desired.After completely melting the metal, the liquid mixture is crystallized with argon and oxygen to remove impurities such as sulfur, excess carbon and slag.To increase product applicability, refined steel is cast into billets, plates, bars,... or different shapes to suit all applications.FormingMost cast steel is shaped by hot rolling into sheet form while the billet is heated and rolled through a large roller to form steel plates, strips or bars.In addition to hot rolling, billets can also be cold rolled to form custom-sized steel blocks. Cold rolling typically uses small diameter wheels to produce a smooth, shiny surface with the smallest tolerances.Heat treatmentStainless steel is heat treated by heating and cooling under controlled conditions to relieve internal stress and soften the stainless steel. However, this stage requires strict control of the annealing temperature to ensure the quality of the stainless steel interior.DescalingAfter annealing and rolling, stainless steel still has a layer of oxidized residue on the surface. The factory needs to clean off the residue to restore the shiny surface of stainless steel. Currently, nitric acid and hydrofluoric acid are the most popular descaling agents. In addition, the electrolytic method is also used to remove residue from the surface.Stainless Steel TemperingThe purpose of heat treatment of steel is to increase the hardness and durability of the material. After annealing, stainless steel tends to become softer. When tempering steel, factories often use water because of its low cost and quick cooling effect. First, experts heat the material to about 815 - 900 degrees Celsius, then transfer the alloy to a water bath to suddenly reduce the temperature, maximizing hardness and durability.Cutting and machiningAfter the above processing steps, stainless steel is almost complete and can be manufactured into various industrial applications. In this step, the factory can cut and process steel into different shapes and sizes by cutting, sawing or techniques such as plasma, high pressure water jet,...Surface finishingStainless steel is famous for its high aesthetics and outstanding corrosion resistance, ease of cleaning and high applicability. To achieve these properties, stainless steel needs to be surface finished by annealing, hot rolling, cold rolling, grinding, polishing, sandblasting,...Methods of controlling stainless steel quality after productionAfter production, stainless steel needs to undergo a number of quality tests before being distributed to the market.Mechanical testMechanical testing measures the physical capabilities of stainless steel such as load-bearing capacity, stress, tensile strength, Brinell, toughness,...Chemical testingChemical testing aims to check whether the chemical properties of stainless steel meet standards through spectroscopic analysis. Besides, factories also test and measure the corrosion resistance level of materials by spraying salt water.If you have any questions or need to import Vietnamese steel, please contact MRS Steel via Email: vanloc@mrssteel.com.vn or Hotline: +842836223358 for the most thoughtful support!

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. Leveraging our deep collaborations with major Vietnamese factories, we can offer you top-quality steel that meets international standards, ensuring the lifespan of the buildings, so this reduces risks of damages and yearly maintenance costs.
