S280GD galvanized steel sheets
S280GD galvanized steel sheets and plates are low-carbon steel that's coated with zinc through the hot-dip galvanizing process to protect it from corrosion. The steel is mainly made of iron, with small amounts of carbon, manganese, and silicon to improve its strength and formability. It has a yield strength of 280 MPa, which makes it suitable for moderate load-bearing applications, according to the EN 10346 standard.
The zinc coating helps prevent rust, making S280GD a good choice for environments with moisture, salt, or other corrosive elements. It's commonly used in construction for roofing and wall panels, in the automotive industry for body panels and undercarriages, and in appliances like refrigerators and washing machines. Thanks to its balance of strength and corrosion resistance, S280GD works well in a variety of industries.
