Grade S320GD is a structural steel with a yield strength of at least 320 MPa.S320GD is available in the following hot dip coatings: S320GD+Z (galvanized), S320GD+ZF (galvanized-iron), S320GD+ZA (galvanized-aluminum), S320GD+AZ (aluminum-zinc), S320GD+AS (galvanized-iron) aluminum silicon).
The thickness of the zinc layer is one of the important factors affecting corrosion resistance. The thicker the zinc layer, the better the corrosion resistance. Generally, the zinc layer thickness of hot-dip galvanized steel sheets is above 30g/m2, even up to 600g/m2, and the zinc layer thickness of S320GD Z275 grade is 275g/m2.
GNEE Steel produces and tests S320GD Z275 galvanized steel coils in strict accordance with EN 10346 standards, ensuring that each batch of products meets customer requirements.
