In this article, MRS Steel will introduce the most popular application of PC Strand in life.1. Concrete productionIn construction, PC Strand can be combined with reinforced concrete types, ensuring constructions with long spans, light but good-bearing structures with optimal cost.PC Strand is also used in the construction of beams and prestressed concrete floors for high-rise buildings to reduce the height of the flooring.2. Irrigation systems, bridges, and roadsPrestressed steel with technical improvements in prestressing, has durability, compressive strength, and anti-corrosion, so it is widely applied in infrastructure works. Specifically, PC Strands are used in irrigation systems such as reinforced concrete dams, retaining wall bridges, dam gates,... For the field of road and bridge construction, adding PC Strand helps prevent beam structure from cracking. In addition, prestressed steel is also used to make 124-130m girder bridge cables. These types of bridges have high durability and long spans, so they are suitable for crossing long distances.3. ParkingPC Strand is used as the primary material in the construction of parking structures because of the following advantages:The ability to resist deflection and movement during seismic situations, earthquakes, violent shaking,...Good resistance to corrosion, wind, and water damage.Build a permanent foundation, and reduce the need for regular maintenance.4. Storage tankGeneral principles when building tanks must use particular types of concrete, have high sustainability in an aggressive environment, ensure waterproof requirements, and have anti-corrosion reinforcement. Therefore, PC Strand is the most suitable material for designing concrete storage tanks that are resistant to internal pressure. This results in a thin, light outer wall layer, reducing the overall weight of the tank but still being able to withstand external forces such as earthquakes, rainstorms,...5. RailsReinforced steel cables have many advantages that other materials cannot meet such as being extremely durable, strong, and resistant to external factors such as the environment and weather. Therefore, they are applied as rails with a design that minimizes the impact of the train on the track surface.6. SewersSewers have strict requirements on materials and design principles to ensure smooth and safe circulation of flows. PC Strands are trusted in sewer systems because they can withstand high pressures and loads. In addition, reinforced steel sewer pipes are resistant to corrosion and do not degrade over time.7. Electricity transmission linesPrestressed steel is widely used in telephone and electricity transmission lines because of its high strength, durability, and resistance to heavy loads from line movement.8. Concrete pavementsThe road surface bears great traffic and weathering, so road projects always emphasize strength and durability. First, the pavement is prestressed with a system of high-strength cables or rods, and then concrete is poured over the top surface to extend the life of the pavement.9. Concrete pilePC Strand is a material that has been improved by prestressing techniques to achieve high strength, compressive strength, and load-bearing capacity, often used in concrete piles. Prestressed concrete brushes are produced by centrifugal rotation with the compressive strength of concrete from B40-B60. It has 2 types of shapes: round pile and square pile, centrifugal concrete grade of 500 or more.10.

On the market today, steel coil is a commonly used type with many different types. However, many people still do not distinguish between the types of steel coils and their uses. Let's find out more about MRS Steel in the following article.1. What is a steel coil? The steel coil is a steel type that is quite commonly used today. This type of steel is produced with a smooth or ribbed surface that is curled together. Making quality steel coils requires a complex steel production process that requires high technical and technological qualifications. Depending on the needs and purposes of use, there will be different types of steel coils.2. Application and classification of steel coil 2.1 Hot rolled coil Hot-rolled coil is the finished product of the process of smelting, casting billets, and hot rolling at a temperature of 10000 °C. This steel is the raw material for creating cold-rolled coil, welded steel tubes, and cast steel pipe. Normally, a hot-rolled coil will have a blue-black color and a rough surface that is less aesthetic.Hot-rolled coils are commonly used in the automobile industry, railways, shipbuilding, roofing corrugated iron, the production of H- and I-shaped steel beams, moving floors, ladders,...2.2. Cold rolled coil The cold-rolled coil is a hot-rolled coil after cooling and re-rolling at room temperature to produce cold-rolled coil products with the desired shape and size. This process will not change the structure of the steel, but only the shape of the steel in accordance with the needs and purposes. However, if the cold rolling process is not strictly controlled, it will deform the product. The cold-rolled coil has a smooth surface, so it ensures higher aesthetics and durability.Cold-rolled coils are often used to make flat sheet products such as steel plates, coils, laminates, round and square details,.. and products with smooth surfaces. 2.3. Galvanized steel coilThe galvanized steel coil is a cold-rolled coil that is additionally plated with a layer of zinc on the outside of the surface. This is one of the most influential and economical methods of protecting steel from corrosion under the influence of the environment.Galvanized steel coils are widely used in building architecture, roofing, ventilation systems, solar water heaters, televisions, refrigerators, the automobile manufacturing industry, the manufacturing industry,...2.4. Stainless steel coilStainless steel is a steel alloy with a minimum chromium content of 10.5%, which is a standard metal in Vietnam and is commonly known as stainless steel.

The cold-rolled coil product is appreciated for its diverse applications and outstanding advantages. So how is cold rolled steel manufactured and what are its current popular applications, all questions will be answered in the article below!What is the cold rolled coil?Cold-rolled steel (trademarked CRC) is generated at the final stage of making steel from billet. Cold rolled coils are produced based on steel billets at low temperatures, more specifically, CRC has origin from hot rolled steel, then it will be processed through a cool process to make the surface become smooth and improve eye-catching brightness.Features of cold rolled coils Cold rolled coil often possesses a glossy surface by an oil layer treated in the rolling process. Besides the smooth surface, the product also offers outstanding durability advantages 20% higher than hot rolled coil. Along with that, cold rolled coil also has good impact resistance and ductile properties, so it is easy to bend and cut on requests.However, because it is still a metal, the cold rolled coil is easy to oxidize if it is not well preserved. Specifically, when the product exists in highly acidic or alkaline environments as well as it has to suffer from harsh weather environments, it will easily cause the steel surface to rust. To overcome this situation, the manufacturer usually has to periodically maintain it by applying a layer of oil to create a protective film for the steel core.Process production of cold rolled coilsThe steel production process will have to go through many separate stages that require strict control to ensure the hardness of the steel and avoid the case that the compositional elements are changed during the period of production.Stage 1 - Preparation of input materials and removing rust surface: the main input material of cold rolled coil is hot rolled coil. Hot rolled coil often brings low aesthetics through the rough appearance, so the manufacturer will proceed to spray a specialized acid directly on the surface to clean it.Stage 2 - Cold rolling stage: the manufacturer will use mechanical force with oil to roll the steel at a low temperature which is equal to room temperature at that time. This cold rolling process has the effect of making the steel structure stronger as well as changing the surface of the steel. However, in principle, the cold rolling process only changes the steel structure and it will keep the original steel's compositions. Because of those technical standards, cold rolling stages will require strict control in order to avoid surface cracking due to excessive force.Stage 3 - Soft annealing: steels that have undergone the cold rolling process will often be in hard condition, so they will be treated with a next step, which is soft annealing. The steel will now be annealed in an electric furnace containing 100% hydrogen gas to help remove the hardness after rolling, enhancing the ductility of the steel to make use of construction applications.Application in specific fieldsDepending on outstanding advantages such as shiny appearance, good loading resistance, cold rolled coil is widely used in the construction, manufacturing and mechanical industries. It also shows some benefits to human daily life. Specifically, some popular areas include:Construction works: taking advantage of the sturdy structure thanks to the low carbon content, people often use CRC for many construction purposes. Some practical applications in popular construction include making structural frames, purlins, ...Machine parts, spare parts for automobile and aircraft equipmentHousehold and consumer appliances: refrigerators, air conditioners, stoves,... Looking for cold rolled coil suppliers directly from Vietnamese factoriesSince the company was established and entered the market until now, MRS Steel has always maintained our mission of being a pioneer in the field of providing comprehensive steel solutions for international importers.
