Q235 galvanized sheet is a surface galvanized sheet with yield strength of 235MPa. 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.
