Gauge 28 galvalume steel corrugated sheet is a building material with excellent corrosion resistance, high heat resistance and good processing performance. It adopts a special coating structure, the surface is smooth, flat and gorgeous star flower shape, and the base color is silver white. The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon by weight, giving it excellent corrosion resistance and anti-aging properties. In addition, galvanized steel sheets have good processing properties and can be stamped, sheared, welded, etc. At the same time, the surface conductivity is good, so it is often used in some environments that require anti-static.
