The coating composition consists of 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. The production process of galvalume-coated steel sheets is similar to that of galvanized steel sheets and aluminum-coated sheets, and is a continuous molten coating process. Galvalume steel sheets with 55% aluminum-zinc alloy coating have superior corrosion resistance compared to galvanized steel sheets of the same thickness when both sides are exposed to the same environment. The galvanized steel plate with 55% aluminum-zinc alloy coating not only has good corrosion resistance, but also the color-coated product has excellent adhesion and flexibility.
