Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel.
The normal service life of the Galvanized 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.
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.
Q195 galvanized coil is a surface galvanized sheet with yield strength of 235MPa. 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.
DX51D Galvanized steel sheet has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion.
Cold galvanizing is generally used less. Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined.
G550 Galvanized pipe belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc.
PPGI is galvanized color plate, PPGL is galvanized color plate, both are color plates, the substrates are different, one is galvanized structure, the other is galvanized structure, the substrate is different, which determines the difference in performance.
Color steel tile roof coatings have advantages such as corrosion resistance, UV protection, and long-lasting color, and have been widely used in the construction industry. Advantages of color steel tile roof coating: 1. Construction is simple and convenient. 2. Corrosion resistance, impact resistance, and durability. 3. The surface is smooth, easy to clean, and prevents bacterial growth. 4. Brightly colored, UV resistant, and can maintain color for a long time. 5. High compressive strength, which can prevent deformation under stress. 6. It can fully avoid water leakage, resist weathering, and have a long service life.
