302 stainless steel is an austenitic stainless steel that has 18% chromium and 8% nickel. Its chemical composition relies heavily on reasonable alloy design to achieve a series of excellent properties.

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

330 stainless steel is a high temperature alloy stainless steel , also known as Incoloy 330 or UNS N08330. It is mainly composed of chromium, nickel, iron and other elements, and has excellent high temperature resistance, high strength and corrosion resistance.

Cold rolled sheet is a product made by rolling hot-rolled coils at room temperature below the recrystallization temperature. Mostly used in automobile manufacturing, electrical products, etc. Cold rolling is rolling at recrystallization temperature, but generally understood as rolling materials using room temperature rolling.

305 stainless steel is a common austenitic stainless steel containing elements such as chromium, nickel, and manganese. Chromium is the main anti-corrosion element and can combine with oxygen to form a dense oxide film to protect materials from corrosion. Nickel can improve the material's heat resistance and toughness while reducing its magnetism.

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, can continue to work at high temperatures, 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.

Galvalumed sheet, with 55% aluminum zinc alloy coating on the surface. The surface of the Galvalumed sheet  presents 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 Galvalumed sheet 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.

Galvanized sheet is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.

DX51D Galvanized steel sheet has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion.

DX52D is a hot-dip galvanized pipe material. In order to improve the corrosion resistance of the steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer is thick, electric galvanized low cost, the surface is not very smooth.
