S250GD Galvanized Steel Advantages and Applications
Ideal for construction, heavy-duty appliances, and transport equipment, S250GD galvanized steel delivers superior weldability, stamping performance, and structural reliability.
Advantages
Enhanced Load Capacity: 250MPa yield strength supports heavier structural loads vs. S220GD.
Corrosion Resistance: Zinc coating (Z20-Z350) of GI steel protects in humid/industrial environments.
Formability: Retains excellent bending/stamping properties for complex part fabrication.
Surface Quality: Uniform coating for painted or exposed architectural applications.
Applications
Construction field: Structural support, roof and wall reinforcement and other components for buildings that need to bear large loads.
Automobile manufacturing field: to meet the demand for automobile lightweight, body parts, chassis structural components, etc..
Home appliance field: shells and structural parts of home appliances with high strength requirements to ensure the stability and durability of home appliances in the process of use.
Others: mechanical parts and equipment shells, electric power towers, communication towers, etc.
