S350GD is a code used to identify hot-dip galvanized steel products that adhere to the EN 10346-2009 European standard. The “S” in the code refers to structural steel, while “350” indicates that the steel’s yield strength is at least 350 MPa. At Wanzhi Steel, we offer an extensive range of continuously hot-dip galvanized steel products, with the highest strength reaching 550MPa. Our range includes S250GD, S320GD, S450GD, S550GD, and more. The sizes range from 0.2 mm-3 mm*600 mm-1500 mm, with zinc coating of 60-275 g/㎡.
Our products are known for their high strength, strong corrosion resistance, and smooth surface finish. They are widely used in various applications such as building materials or structural parts, including roofing, wall panels, ventilation pipes, interior decoration, fencing, steel frames, and more.

S350GD is a code of hot dip galvanized steel, which is a type of structural steel that has a minimum yield strength of 350 MPa. It is often followed by “+Z” or “+AZ” and number, which indicates the thickness of the zinc or aluzinc coating. For instance, S350GD+Z275 refers to galvanized steel that has been coated with a zinc layer weighing 275 g/㎡, while S350GD+AZ150 refers to galvalume steel coated with an aluminum-zinc alloy weighing 1.5 ounces per square foot.

Let’s learn the meaning of the codes first.
SGCC (JIS G3302): S- Steel; G- Galvanized; C- Cold rolled steel; C- for common uses; which is equivalent to DX51D+Z.
SGHC: S- Steel; G- Galvanized; H- Hot rolled steel; C- for common uses;
S350GD: S- Structural steel; 350- yield strength should be at least 350MPa; GD- Galvanized;
DX51D: D- low carbon steel; X – the rolling state of the substrate is not specified; 51 – steel grade for common uses; D- Galvanized.
