The surface of the GL steel sheet is uniquely smooth, flat and gorgeous with star-shaped patterns, and the base color is silver-white. The special coating structure gives it excellent corrosion resistance. The normal service life of the galvanized steel sheet can reach 25 years, and it has good heat resistance and can be used in a high temperature environment of 315°C; the coating has good adhesion to the paint film, has good processing performance, and can be stamped, sheared, welded, etc.; the surface conductivity is very good.
The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminum-plated sheet, which is a continuous molten coating process. The 55% aluminum-zinc alloy-coated galvanized steel sheet has superior corrosion resistance compared to the galvanized steel sheet of the same thickness when both sides are exposed to the same environment. The 55% aluminum-zinc alloy-coated galvanized steel sheet not only has good corrosion resistance, but the color-coated product has excellent adhesion and flexibility.
