stainless steel coil is a thin steel plate supplied in coils, also called strip steel. There are imported and domestic products, divided into hot-rolled and cold-rolled. According to the needs of different users, we can also order a variety of special-shaped steel materials.In order to ensure that the yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery.

Carbon steel coil is a commonly used metal material with a wide range of applications in many fields. It has good mechanical and processing properties and is widely used in fields such as automobile manufacturing, shipbuilding, construction, and bridges.

Galvanized coil, a thin steel sheet that is dipped into a molten zinc bath to adhere a layer of zinc to its surface. It is mainly produced by the continuous galvanizing process, in which rolls of steel sheet are continuously dipped into a bath of molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This steel sheet is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to about 500°C to produce an alloyed coating of zinc and iron. This type of galvanized coil has good paint adhesion and weldability.

The surface of the Galvalume  Coil  is a unique smooth, flat and gorgeous star, and the basic color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the Galvalume  Coil can reach 25a, and the heat resistance is very good, which can be used in the high temperature environment of 315 ℃; The coating has good adhesion with the paint film, has good processing performance, and can be punched, sheared, welded, etc; The surface conductivity is very good. 

Color Coated sheet is also called color coated sheet, also called organic coated sheet or pre-coated steel sheet, which is based on metal coil (cold-rolled sheet, hot-dip galvanized sheet, aluminized sheet, high aluminum alloy sheet, stainless steel sheet, etc.) It is formed by coating or laminating various organic coatings or plastic films on the surface. Because it is a coil that has been surface-coated in a metallurgical plant and can be directly processed into products by users, it is also called a pre-coated coil.

304 stainless steel is a superior material with regard to corrosion resistance, heat resistance, low temperature strength and mechanical properties, as one of the most widely used types of stainless steel. In addition, it has exceptional hot-workability such as stamping and bending, without leaving heat treatment hardening phenomenon.

304L stainless steel is remarkably similar to 304 stainless steel in their chemical composition with one key difference. the maximum carbon of 304L stainless steel content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. This is why the “L” in 304L can be interpreted as extra-low carbon.

310S stainless steel is austenitic chromium-nickel stainless steel, with good oxidation resistance, corrosion resistance, because of a higher percentage of chromium and nickel, so that it has much better creep strength, with good high temperature resistance.

316 stainless steel also contains 2-3% molybdenum, in addition to iron, chromium and nickel. The addition of molybdenum significantly improves the performance of 316 stainless steel in certain corrosive environments, especially those containing chlorides. 316 stainless steel is more commonly used in situations requiring higher corrosion resistance.

316L stainless steel features a lower proportion of carbon in its composition. The amount of carbon cannot be higher 0.03%. This lowers the risk of carbon precipitation, making it a better option for welding to achieve maximum corrosion resistance.

309 stainless steel is a stainless steel material with excellent corrosion resistance and high temperature performance. It is commonly put into use in aviation, chemical industry, petroleum, food and other fields.

321 stainless steel is an austenitic stainless steel of excellent corrosion resistance at room temperature, as well as good high-temperature strength and creep resistance.

201 stainless steel is the steel that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid resistant steel refers to the steel that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.

A36 is a carbon structural steel coil whose chemical composition and mechanical properties strictly conform to American ASTM standards. Good mechanical properties, welding performance and corrosion resistance are basically why they are widely used in construction, bridges, machinery manufacturing and other fields.

ASTM A283 cold rolled steel coil has low and medium tensile strength. The ASTM A283 steel specification covers four structural quality grades of mild steel, grades A, B, C, and D, for general application.
