Black steel is a type of steel that plays an important role in many projects as well as applications related to life. So what is black steel pipe and its advantages to make it is used in so many projects like that, today let's learn about black steel pipe with MRS Steel with the most detail in the article below!1. Definition about black steel pie and the important specificationsBlack steel pipe is a product created on the hot rolling process of black steel sheet material, it can be said that this pipe is a form of steel that has not been galvanized. Instead of going through a galvanizing process like many other steels, this steel just undergoes a chemical conversion to create a black or magnetic iron oxide layer. Therefore, the surface this steel is often dark blue and rough based on the dark iron oxide shell on its surface.Black steel pipe is produced based on certain standards and parameters, usually there are 2 standards most commonly applied today to evaluate black steel pipes including ASTM A53 and ASTM A106.Accordingly, the ASTM A53 standard will include the required metal components such as Carbon, Manganese, Phosphorus, Nickel, Chromium, Molybdenum and Vanadium in small proportions, the composition is mainly Iron. In which the sum of 5 elements Copper, Chromium, Molybdenum, Nickel and Vanadium must be less than 1%.ElementsPercentagesCMax 0.3%MnMax 1.2%PMax 0.5%SMax 0.045% ASTM A106 standard is a seamless black steel pipe, meaning that they will not have the joints as basic steel pipe and they are commonly used in high temperature environments. The composition of ASTM A106 type will be similar to that of standard A53, there are only minor differences as the total composition of this standard is now supplemented with Silicon.ElementsPercentagesCMax 0.35MnMax 1.06PMax 0.35SMax 0.0352. History of formation and manufacturing processes of black steel pipeMethods of producing pipe steel appeared as early as more than 200 years ago and they have been gradually researched and developed to this day. The origin of steel pipes appeared in the 1800s when a British inventor created a system of coal-fired lamps to light up the street, from which the need to use steel pipes has paid attention day by day.In the early stages in the 1820s, researchers at that time created metal pipes by using fire to soften the metal sheet and proceed to join the metal edges and weld them together with a hammer. However, this method was replaced by a more advanced method and it is considered the premise for today's method of forming steel pipes. Basically, the metal sheets will be heated until a certain ductility is reached, then the manufacturer will pull them through a conical groove. As the metal passes through the groove, the edges of the metal will gradually roll and contract to form a long, round tubular shape.2.1. Manufacturing processes of welded steel pipeNowadays, the production methods of black steel pipe have been gradually automated by equipment, so the completion time is greatly accelerated while ensuring the technical uniformity. Black steel pipe is divided into 2 common types, namely welded steel pipe and seamless pipe steel, specifically, the production process of welded pipe steel takes place as follows:Slitting line stage: The manufacturer will put hot rolled steel coils into the slitting machine to cut the steel sheets into small widths.Rolling: Then the slitting steel will be moved through the clusters and cages to flatten and chamfer on both sides, making the steel surface uniform in size.Shaping: Next is the shaping stage, the steel strip then goes through a series of grooved rollers arranged parallel to both sides, as the steel moves towards the end, their shape will gradually be rolled to form a cylindrical shape.Welding black steel pipes: This is the step that requires the most technical machines because the joint line will greatly determine the durability of the black steel pipe in the future. The steel pipe will pass through a roller arranged above to create extremely strong friction on the groove. At the same time, both the inside and outside of the pipe are also sprayed with hot zinc to avoid the risk of rusting the joints.Quality check: Once the steel pipes have been successfully shaped, they will now go through the cutting machines to complete the final stage. Black steel pipes go through modern gauges to compare technical information as required to ensure the stability and quality of the finished product before being put on the market.2.2. Manufacturing processes of seamless steel pipeIn contrast to welded steel pipe, seamless steel pipe is derived from a billet, which is then heated and cast to form a hollow section steel. Seamless steel pipe production processes began to appear in the late 19th century and it gradually replaced welded steel pipe because the manufacturing process usually took place quickly in a relatively short period of time. Therefore, during World War II, seamless black steel pipes completely took advantage of applying in life and making weaponry at that time.Currently, manufacturers usually apply one of two main manufacturing processes to create seamless steel pipe including the Mandrel Mill process and the Mannesmann Plug Mill process. Both processes serve different purposes as Mandrel Mill is used to produce small diameter steel tubes from 25 - 150mm. Whereas the Mannesmann Plug Mill process produces seamless steel tubes with large diameters from 150 to 400 mm.Mandrel Mill processThe process begins with a billet bar heated to 1300 degrees Celsius and then the manufacturer will use a long piercing to drill into the top of the billet bar to create a small hole and this gap is the starting point for radius expansion taking place afterwards. The piercing tool will rotate continuously into the center of the steel pipe and this rotation speed is enough to cause the steel core to gradually melt through its path.After the steel pipe is successfully penetrated, it will move to the mandrel mill installed on the pipe. The series of rolls here are arranged in the direction of 90 degrees to continuously roll the surface of the steel pipe to reduce the outside diameter and control the thickness. When leaving the furnace and meeting the standard outside diameter, the steel pipe will now undergo a cleaning step with high-pressure water descale to remove excess oxide deposits formed during heating. They are finally moved to the cutoff mechanism to be cut to the prescribed length, then they will be bundled and checked again before implementing shipment.Mannesmann plug mill processThe process begins with a billet that has just been heated from the furnace and then the manufacturer will use a Mannesmann drill with the head is designed in a conical shape and the size is almost equal to the diameter of the pipe. This drill will rotate continuously into the center of the steel pipe diameter to create a large enough hollow.During the steel hollow drilling process, on the production line, two rollers will be installed in the opposite direction of the steel to reduce the steel diameter thickness. In order to ensure the quality of the hollow inside, the manufacturer will use a cylindrical mandrel with a size close to the hollow diameter inside it to rotate, the purposing of this stage is control the roundness inside the pipe. Then, the steel pipe is put into the decontaminating stage and be cutted to the required length, finally the product will go through heat treatment and cooling.3. The characteristics and role of black steel pipe in the current contextA great advantage that black steel pipe brings to the project is its affordable price. Thanks to the quick and simple production process without too much technical technology, the market price of black steel pipe is always reasonable, the level price is always in the low range. Cheap input materials will help managers be more proactive in investing in other areas of the project, thereby helping the plan become stable and reduce the risk of capital shortage. Although the price is cheap, this does not affect the quality of the steel, specifically the black steel pipes have high homogeneity thanks to the production process on the same line, so the durability as well as the mechanical properties are not compromised and they obtain consistency from beginning stage to the end stage. In addition, black steel pipe will not shrink when exposed to high temperatures, the nature of black pipe steel is formed from billet with a temperature of up to 1500 degrees Celsius, so it can keep the original shape even after being heated.However, the black steel pipe is considered for environmental problems in its production process because the production requires the factory to burn fossil fuels and this leads to the large amount of smoke emitted into the atmosphere, polluting water and soil. In terms of long-term economic impacts, this steel pipe is still an ideal choice as the steel's durability has kept it existing for decades, this steel pipe is possible to become an optimal economical solution for the facility infrastructure as well as other manufacturing applications.Green steel production projects have been gradually popularized to many places of the world, green steel technology completely eliminates the use of fossil fuels from the process, helping the mills cut down on up to 90% the amount of carbon emissions. The importance of scrap steel is also being concerned by many manufacturers when it helps businesses save energy resources and be more proactive in finding input raw materials without having to invest in eloring natural mining sites.4. Applications of black steel pipe in the fieldsPossessing a variety of diameters from 12x12 mm to 100x100 mm and even up to 250x250mm, black steel pipe is now an important factor in the construction field and many industries.4.1. Pipeline systemOne of the most common applications of pipe steel is taking advantage of making water, vapor and natural gas pipelines. Black steel pipe possesses good bearing capacity without distorting, so it will be suitable as a conduit at high pressure places. In addition, these pipes also appear in oil and gas pipelines because they are manufactured according to standard specifications so they can adapt well to corrosion and high temperature environments. Various lengths and sizes of steel pipes have made it easier for businesses to install at the locations, specifically in the installation of water and gas pipelines in urban and rural areas. Moreover, black steel pipes usually require less frequent maintenance, so they can be installed underground, which helps to increase the urban beauty with less obstruction to the surrounding ground.4.2. Building structureIn construction, black steel pipe is used as the foundation of the building as well as appearing in load-bearing scaffolding. Steel pipe has a chemical composition including chromium, silicon to increase the strength and toughness of steel pipes, so it has the function of balancing and distributing the load evenly for the foundation with the scaffolding.Black steel pipe also appears in the ultrasonic pile system in the foundation structure of the building and it is the main raw material of pre-engineered steel buildings, the light weight of this pipe will help the construction process become more convenient and easier.5. The difference between black steel pipe compared to other steelsBesides black steel pipe, there are many other types of steel pipe that are the same size and shape as black  pipe, moreover, they are very popular in construction and industrial applications. Some typical steel pipe products placed on the balance sheet compared with black steel pipes can be mentioned as carbon steel pipes and galvanized steel pipes.5.1 Black steel pipe and carbon steel pipeBlack steel pipe and carbon steel pipe basically still have the basic thing in common, which is an iron alloy with added carbon to create strength. Both types have the similar advantage of being extremely sturdy and durable, so they are very popularly used in the fields of construction and manufacturing engineering. However, if you examine closely each type of steel, you will see that they have significant differences.Structural compositionIn terms of composition, the amount of carbon in steel is also divided into different abundance levels from 0.05% to 2%. Meanwhile, black steel pipe has regulations on the amount of carbon content not exceeding 0.35%. Although the black pipe has a much smaller amount of carbon, they contain elements that carbon steel pipe does not possess such as chromium, silicon and manganese, which are extremely valuable in resisting corrosion and maintaining durability for steel.Carbon steels are composed mainly of iron and carbon, they have the least chromium content compared to other steels. The element chromium gives effective corrosion resistance to steel, so the absence of chromium will make the steel very susceptible to oxidation and rust surfaces.Strength and enduranceEvaluation of strength criteria, black steel pipe is more durable and harder than carbon steel pipe because the black iron oxide coating helps increase the hardness of the material, has the effect of protecting the surface of the steel pipe and effectively resisting corrosion. Meanwhile, because carbon steel pipe does not have additional anti-corrosion elements, its durability will be worse than black pipe steel, even when the atmospheric humidity increases to 70%, it can also cause carbon steel to oxidize.Black steel pipes on the market today are not usually required to be galvanized because they are equipped with a protective layer against corrosion that is formed through the manufacturing process, while carbon steel will require the manufacturer to proceed galvanizing steps to ensure they do not corrode. Especially in gas transportation or plumbing applications, carbon steel is not an appropriate choice.Eco-friendly in manufacturingThe use of black pipes for construction and industrial applications is considered more eco-friendly than carbon steel pipes. The reason is that the emissions from the production of carbon steel pipes are more than the leaking smoke in the production of black steel pipe. The reason why is that the carbon component accounts for the largest proportion of carbon steel pipe while black steel pipe may not need or will exist very little carbon components. Therefore, many people predict that in the future, it is likely that this black steel will gradually replace carbon steel in many fields before the trend of green economic development globally.5.2 Black steel pipe and galvanized steel pipeBlack steel pipe and galvanized steel pipe are the two most widely used steels in the transportation of oil, gas, water and other liquids. Both are tubular steels and have the same application, but if you put them on the scale, you will see that these two steels are significantly different.Corrosion resistanceAlthough black steel pipe coated with iron oxide has a significant effect on oxidation resistance, this steel is not superior to galvanized steel pipe. Galvanized pipes are coated with a layer of zinc and zinc is one of the leading elements for effective anti-corrosion, in addition, the zinc layer also helps prevent steel from being scratched and helps the steel surface to be maintained in the best condition.Pipeline system applicationsThe thicker the zinc layer, the longer the life of the steel, but some studies on air pipeline systems have shown that this zinc coating can peel off and clog pipes, leading to damage for pipe. Therefore, although galvanized steel pipe is very popular in liquid transmission systems, it is not suitable for gas transmission systems.In contrast, black steel pipe is proven to be a good air transportation product as well as used for fire protection systems because black steel pipe can withstand higher temperatures than galvanized steel pipe. However, black steel pipe is not a good choice for use as a pipeline for compounds with high concentrations of corrosive because this compound will dissolve into black steel pipe and cause pipeline blockage.Production cost and priceBlack steel pipe and galvanized steel pipe have a clear difference in cost because in the production process, manufacturers have to perform additional galvanizing steps for steel, so the cost to sell to the market will be higher than that of black steel pipe. In addition, during time for implementing the construction or commercial buildings, galvanized steel pipes will never be connected to black steel pipes.6. Looking for a reputable black steel pipe supplier in VietnamThanks to its outstanding properties and affordable price, black steel pipe is always present in most construction projects as well as water and gas transmission systems.

Food and cateringStainless steel is a familiar material in many kitchen utensils. Thanks to its good corrosion resistance, high durability and safety for users, stainless steel is often made into stoves, grills, pots and pans,... Currently, stainless steel is also used as a finishing layer for refrigerators, washing machines, dishwashers,...2. Offshore technologyStainless steel's corrosion resistance in both coastal and high-salinity marine environments makes it suitable for offshore applications. In particular, Austenitic stainless steel containing 6% Molybdenum can be permanently immersed in seawater. There are many applications of stainless steel in the offshore industry, for example:- Submersible components: Oil pipes and grids, heat exchangers for ships, coastal power plants, ship hull accessories,...- Platform structure components: Pumps, tanks, rebars, cable trays, stairs, walkways, oil and gas coolers,...- Parts and details on boat and ship such as deck eyes, anchor rope brackets, shackles,...3. Desalination plantsStainless steel is an alloy of iron, nickel, chromium, molybdenum and many other elements that give it excellent durability and corrosion resistance. It accounts for 20-30% of equipment in desalination plants. Chromium forms a “passive” layer on the surface of stainless steel, protecting it from chemical reactions and environmental factors that lead to corrosion. This layer also enhances stainless steel's resistance to pitting, crevice corrosion and many common problems in marine environments. The most common stainless steel grades in desalination plants are 304L, 316L and duplex grades 2205 and 2507.4. Chemical industryChemical mills contain dangerous acids and oxidants that can cause extremely serious damage to common metals. Meanwhile, in addition to standard corrosion resistance, stainless steel is also resistant to stress corrosion cracking and galvanic corrosion. Some other alloys also have good durability and can withstand high temperatures in harsh environments such as the oil and gas industry. That's why stainless steel is a preferred choice for chemical storage tanks, pumps, and pipelines.5. BridgesThe excellent properties of stainless steel play an important role in long-span bridge applications, highway bridges, pedestrian bridges and even railway bridges. The use of stainless steel is increasingly popular due to its durability and aesthetic appeal. Initially, stainless steel was mainly used in safety parts such as handrails and railings. In recent years, they have also been made into floor structures and suspension systems.6. Storage tanksStainless steel, with higher durability compared to concrete, plastic and carbon steel, possesses oxidation from water and biocides. These characteristics make it ideal for water and food storage tanks. Additionally, stainless steel tanks are highly resistant to crevice corrosion and cavitation.7. Civil engineeringStainless steel has long been popular in construction because of its advantages of durability, toughness, aesthetics and longevity. Typical applications of Austenitic and Duplex stainless steel are load-bearing components, beams, columns, supports, seawalls, ... In addition, stainless steel can also be shaped through cold forming, extrusion or laser fusion to produce bolts, screws and structural steel.8. Power plantsStainless steel is one of the metals with high applications in the electrical and energy industry. The chromium oxide film on the surface protects the steel from corrosion and self-heals after scratches. Another characteristic that makes stainless steel suitable for the power plants is its ability to transfer heat and withstand high temperatures and pressures. That is why stainless steel is often used in heat exchangers, pressure tubes, transformer enclosures,… 9. Shipbuilding industryBasically, a ship built with aluminum alloy will be 60% lighter than steel and is more resistant to corrosion and easier to maintain. Stainless steel contains high nickel content, making the steel's mechanical properties more stable and durable over time. This is also the element that helps steel resist oxidation in the marine environment, making stainless steel highly suitable for the shipbuilding industry.10. Medical industryStainless steel contains a minimum of 10.5% chromium, forming a “passive” layer that prevents the surface from corroding. Stainless steel is also popular in the pharmaceutical industry, where hygiene and safety are strict.

The most important factor of a sustainable building is the source of quality construction steel. Depending on the property of each project, the contractor will choose some criterias to evaluate construction steel. Below is a list of common criteria for evaluating the quality of construction steel.Construction steel quality standardsThere are countless different types of steel on the market today, in order to create a common uniformity in the steel production process, quality standards have been issued. Manufacturing mills will often rely on these quality standards to adjust the specifications to ensure the quality of the steel grade is in the best condition.Three common quality standards including Vietnamese, American and Japanese standards are applied to steel constructions such as plain bar and rebar. In which, when the product meets Vietnamese standards, construction steel is considered as standard steel and is completely suitable for construction projects.TCVN - Vietnam steel standardVietnam confirms quality standards for steel grades is abbreviated in the form of TCVN, of which there are 4 general standards: TCVN 1651-1:2008, TCVN 1811_2009 (ISO 14284-1996), TCVN 6287_1997, TCVN 7937-1-2013.The plain bar steel used to make reinforced concrete and on each of them are marked CB240-T, CB300-T and CB400-T. Similar to plain bar steel, rebar steel also owns 3 standard steel grades including CB300-V, CB400-V, CB500-V, CB600-V. The numbers in the symbol will represent the strength of the steel. Specifically, the CB300-T series will indicate the value of strength is up to 300N/mm2, meaning that a steel bar with a cross section of 1mm2 will withstand a tensile force of up to 300N (equivalent to 30kg).ASTM - American steel standardThe American Standard is identified by its common abbreviation ASTM, will focus on key topics such as specifications, testing, and grading guidelines. The American standard applied in the current range of construction concrete steels is ASTM A615/A615M with 3 steel grades including GR40, GR60 and GR75.Most steel grades according to American standards are highly appreciated for their outstanding hardness when all 3 steel grades GR40, GR60 and GR75 possess tensile strengths of 420 MPa, 620MPa and 695MPa. Having the high tensile strength will be a plus point of this standard for building framing applications because they provide extremely good loading.JIS - Japanese steel standardThe Japanese standard is also one of the familiar standards in the steel industry with the abbreviation JIS. Currently, two popular Japanese standards are applied in construction steel including JIS G3505 - 1996, JIS G3112 - 1987.Construction steel specificationAnother important criterion in the selection of construction steel is the appropriate size including diameter, length and volume. Knowing the construction steel diameter will help the contractor easily calculate the required volume of construction steel for the project, especially for large projects that always require meticulousness and calculation in detail.If the contractor is not careful in choosing the right size, it is easy to make the structure weak because of unbalanced transmission forces in some loading parts. Famous construction steel suppliers in the Vietnam market such as Hoa Phat, Pomina, Viet Italy, ... are at risk of being faked as poor quality versions. Normally, the fake version of construction steel will have a smaller size from 0.5 - 0.8mm than the authentic one.Specification of steel standard TCVN 1651-2008Outside diameterΦ6Φ8D8D10D12D14D16D20D25D32D36D40D50Cross section(mm2)28.350.2750.277.8511315420131449180410181 2571 694Specific weight (kg/m)0.2220.3950.3950.6170.8881.211.582.473.856.317.999.8615.42Tolerance specific weight (%)±8±8±8±6±6±5±5±5±4±4±4±4±4 Specification of steel standard JIS G3112 - 1987Outside diameterD10D13D16D19D22D25D29D32D35D38Cross section(mm2)71.33126.7198.6286.5387.1506.7642.4794.2956.61140Specific weight (kg/m)0.560.9951.5592.2493.0393.9785.0436.2347.5098.949Tolerance specific weight (%)±6±6±5±5±5±5±4±4±4±4 Specification of steel standard ASTM A615/ A615M-08Outside diameterD10D13D16D19D22D25D29D32D36Cross section(mm2)711291992843875106458191006Specific weight (kg/m)0.560.9941.5522.2353.0423.9735.066.4047.907Tolerance specific weight (%)±6±6±6±6±6±6±6±6±6 Steel origin and the market priceThe standard steels must be the steel lines having clear origin, usually the manufacturer will attach labels showing characteristic symbols and brand names on each steel bundle.In addition, quality construction steels from reputable brands will always have a fixed price and the retail price will be listed from the manufacturer. If the price of steel is too low compared to the factory's selling price, it means that the quality of the steel will not be guaranteed.Quality construction steel must come from a reputable supplierBesides considering the quality criteria, choosing a reputable steel supplier is also an important factor to help get good construction steel.

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.
