Topics regarding the characteristics of galvanized steel pipe vs black steel pipe are frequently compared because these two are common materials in construction applications, piping systems, and various manufacturing fields. Although both are types of steel pipes, comparing their characteristics reveals significant differences.To begin, let's explore the key differences between galvanized steel pipe and black steel pipe? Which type of pipe is best suited for contractors in specific applications? Read the article now and answer these questions with MRS Steel in the following lines!The characteristics of galvanized steel pipe vs black steel pipes differ significantlyDefinition and structural composition of galvanized steel pipe vs black steel pipeThe main distinction of galvanized steel pipe vs black steel pipe is its appearance, specifically the presence of a zinc coating. Galvanized steel pipes are essentially formed from carbon steel but the manufacturer applies an additional layer of zinc to enhance their resistance to corrosion and oxidation. Therefore, when used over a long period, the zinc layer acts as a sacrificial layer and will rust before the oxidizing agents reach the base steel layer.On the other hand, black steel pipes do not undergo the galvanizing process. They are identified by their characteristic dark or matte surface. This coloration is formed by a layer of black iron oxide, which results from the reaction between oxygen and iron during the production process. Although galvanized steel pipe and black steel pipe have significant differences in their external characteristics, they both share the same carbon steel core.Galvanized and black steel pipes have same steel core layer but differ in surface treatmentComparing the properties of galvanized steel pipe vs black steel pipeBased on the differences in their coatings, galvanized steel pipe and black steel pipe each have their own advantages and disadvantages in terms of corrosion resistance, strength, and durability. Furthermore, each type has its specific purposes and suitability for various industrial applications.Corrosion resistanceThe corrosion resistance of galvanized steel pipe is rated better than that of black steel pipe due to the zinc coating on the surface. Specifically, the galvanized coating acts as a sacrificial anode, interacting with H2O molecules to form zinc hydroxide, which helps prevent the contact of water and air, thereby protecting the steel from oxidation and corrosion.In contrast, the surface of black steel pipe is only covered with a layer of iron oxide as a result of the reaction between the iron in the steel and the air. This coating does not significantly prevent corrosive agents, and their structure is not durable and can be easily broken down when exposed to salt or acids.One way to protect black steel pipes from oxidation is to place them in dry environments or areas with stable climatic conditions with low levels of salt and acidity. Additionally, to enhance rust resistance, black steel pipes can be coated with paint or other protective layers after installation.Galvanized steel pipe has higher corrosion resistance through its zinc layerSteel strength and durabilityIn terms of steel strength, both types of steel originate from carbon steel, so they generally contain carbon content ranging from 0.25% to 0.55%, along with a few other alloys such as manganese, phosphorus, etc. This amount is sufficient to ensure a balance between hardness for good load-bearing capacity and flexibility in machining applications.Galvanized steel pipe and black steel pipe both have natural heat resistance and can withstand pressures up to 150 PSI, as both types of steel have melting points up to 1370 degrees Celsius. Therefore, under natural environmental conditions or in harsh environments, the temperature will never reach levels that could damage the steel structure, except in cases where machining processes generate temperatures exceeding their endurance limits.However, the thicker the coating, the better the steel product can withstand all weather conditions. Specifically, the zinc coating can extend the lifespan of steel pipes up to 50 years. When comparing durability, there is a significant disparity of galvanized steel pipe vs black steel pipe. Due to the lack of a protective coating, black steel pipes, although having good mechanical properties initially, tend to deteriorate and lose durability over time during use.Both steel types have good heat resistance with the melting point to 1370 degrees CelsiusFlexibility in machiningIn machining applications, workers often prefer black steel pipe vs galvanized steel pipe because this steel type does not have a zinc coating. Therefore, they can be easily cut, bent, and welded without worrying about damaging the protective layer. In contrast, galvanized steel pipe has a zinc coating, which can pose a risk of poisoning to the worker when machining, especially during welding.Additionally, black steel pipes are produced through a hot rolling and welding process, which creates a seam along the length of the pipe. During pipe connection operations, black steel pipes are easier to work with compared to galvanized steel pipes because the seam makes them extremely easy to install without the need for welding.Without zinc layer in surface, black steel pipe can be easily cut, bend and weldedApplications of galvanized vs black steel pipeFields such as construction, pipeline systems, and automotive manufacturing are the three most common application sectors for galvanized steel pipe and black steel pipe. However, within these fields, each type of steel demonstrates distinct and appropriate aspects!ConstructionThe robustness providing excellent load-bearing capacity and resistance to corrosion has made galvanized steel pipe and black steel pipe are crucial materials for construction projects. However, in outdoor structures of infrastructure like railings, fences, and scaffolding frames, contractors prefer galvanized steel pipe vs black steel pipe due to its ability to withstand weather impacts and ensure long-term durability.On the other hand, black steel, known for its strong load-bearing capacity and ease of fabrication and assembly, is often used for indoor structures where there is less direct exposure to weather, such as framework, temporary structures, or water piping systems. Currently, black steel pipes are more readily available on the market compared to galvanized steel pipes because their manufacturing process is typically simpler and less costly.Galvanized steel pipe is used for outdoor structures in construction projectsPiping systemsPiping systems are considered the most common application for galvanized steel pipe and black steel pipe. Particularly when considering water piping systems and other liquids such as oil pipelines, waste pipelines, chemical pipelines, etc., manufacturers prefer galvanized steel pipe vs black steel pipe due to its smooth zinc coating surface, which helps prevent the accumulation of mineral deposits that could clog water pipes.Although black steel pipes are more common, they are often not prioritized in applications for fluid piping systems because this type of steel lacks a protective coating. As a result, black steel pipes are susceptible to corrosion and rust when exposed to fluids. Instead, black steel pipes are used for propane or natural gas piping systems to residential and commercial buildings. Additionally, this steel type is also used in fire sprinkler systems because this type of steel has better heat resistance and fire resistance compared to galvanized steel pipes.Galvanized is applied for liquid piping systems while black steel pipe is common in natural gas piping systemsOther common applicationsBlack steel pipe and galvanized steel pipe both have numerous important applications in various industries beyond construction and piping systems. In the automotive industry, galvanized steel pipe can be used in exhaust systems of vehicles due to their corrosion resistance or for components exposed to external environments. Additionally, galvanized pipes are also prevalent in the energy sector, where they are used in support structures for solar panel arrays because of their ability to withstand harsh weather conditions.Black steel pipes, known for its ease of fabrication and high mechanical strength, are used in mechanical structures within the mechanical engineering industry. Moreover, they find application in manufacturing furniture frames and tables in the interior design sector. Their ease of fabrication supports easy bending and cutting operations, facilitating the creation of diverse designs with high durability.Galvanized steel pipes are used in the energy sector as supports for solar panelsGalvanized steel pipe vs black steel pipe: Which material costs more?Comparing the cost of galvanized steel pipe vs black steel pipe, generally, black steel pipes are cheaper because in the manufacturing process of this material, they do not undergo the galvanizing stage. The absence of a protective zinc coating reduces raw material costs, making this type of steel a more economical choice for applications that do not require high corrosion resistance.Black steel pipes will help optimize project costs better than galvanized steel pipesSave time and cost on galvanized and black steel pipe purchases with MRS SteelIn summary, galvanized steel pipes are the perfect choice for applications requiring high durability and corrosion resistance, especially projects in harsh environmental conditions. On the other hand, black steel pipes are a sensible choice due to their combination of mechanical strength, durability, and cost-effectiveness. The selection between galvanized and black steel pipe will depend on the specific technical requirements of the project along with considerations of cost.Through this article, MRS Steel aims to provide readers with a comparative perspective on the properties of galvanized steel pipe vs black steel pipe, thereby assisting in the selection of the most suitable material for their projects.

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. Choosing quality black steel pipe products directly sourced from large factories in Vietnam will bring a lot of sustainable value to your project.Currently, the price of black pipe steel is constantly changing because the Vietnamese steel market in particular and the global steel market are still in a difficult period.

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. MRS Steel as an expert in providing steel solutions for importers will be the ideal partner to accompany you in the process of searching and trading products.During many years of operations, MRS Steel has made many close relationships with major domestic manufacturers.
