Galvanized sheet G550 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. 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 following are some specifications that we often export, for reference only, if you have special requirements, we can customize, we will have professional designers to provide you with the most satisfactory style.
