Definition
S350gd is a grade in the European standard “EN 10346-2009 Continuous Hot-Dip Galvanized Steel Sheet Products”, which is a galvanized steel sheet. S350G is structural steel requiring tensile strength greater than 350MPa, D means galvanized sheet, so s350gd is structural galvanized sheet with yield strength greater than 350MPa
The S350G is available in the following hot dip coatings: S350GD+Z (galvanized), S350GD+ZF (galvanized-iron), S350GD+ZA (galvanized-aluminum), S350GD+AZ (aluminum-zinc), S350GD+AS (galvanized-iron) aluminum silicon).
Features
S350GD galvanized sheet (coil) has the characteristics of strong coating adhesion, strong erosion resistance, precise control of galvanized layer thickness, high dimensional accuracy, flat profile, good mechanical properties, processing performance and welding performance. They can be used to manufacture interior and exterior panels, structural parts and reinforcements for automobiles.

Summarize
Since the standard potential of zinc is negative than that of iron, the galvanized layer of S350GD galvanized sheet can protect the steel base in water and humid air, which can greatly prolong the service life of the steel. The galvanized layers commonly used in industry include hot-dip galvanizing, electro-galvanizing, mechanical galvanizing, etc.
