Mild Steel S250gd+z275 Galvanized Steel

 

S250GD+Z275 is a double-sided hot-dip galvanized structural steel according to EN 10346 with a guaranteed minimum yield strength of 250 MPa. The Z275 coating represents a zinc coating of 275 g/m² on both sides and offers excellent corrosion protection. The steel combines strength with good cold formability and is ideally suited for load-bearing and bracing sheet metal components in construction.

 

Galvanized steel coil is one of the hot-selling products of GNEE Steel. It is available in big, regular, small,and zero spangles. Compared to color steel coil, it is more affordable. Also,it has excellent corrosionresistance and durability. That's why it is extensively used in construction, automobile, furniture, homeappliances,etc. Due to its wide applications and good machinability,it is also a great investment project.As a wholesale supplier, GNEE Steel has its own factory to meet bulk orders timely. Also, we will offer adirect-sale price to lower your cost. If you are interested, please contact us for details!

• Superior Corrosion Resistance: The substantial zinc coating thickness of Z275 forms a robust protective barrier on the substrate, making it suitable for corrosive environments such as coastal high-salt-fog areas and humid industrial zones.
• Excellent Formability: Utilizing premium steel grades like DX54D, DX53D, DX52D, DX51D, S250GD, and SGCH, it meets both standard processing and ultra-deep drawing requirements.
• Diverse Surface Types: Four zinc flower patterns with multiple surface treatments offer practicality and aesthetics, catering to various industry needs.
