Dx51D galvanized steel plate is a hot-dip zinc-coated sheet widely used across industries for its excellent corrosion resistance, durability, and cost-effectiveness. Manufactured through advanced galvanization techniques, this steel plate is designed to withstand harsh environments while maintaining superior formability and mechanical strength. It is an ideal choice for construction, automotive, home appliances, machinery, and various industrial applications.
The Dx51D galvanized steel sheet is produced through a hot dip galvanizing process, where the base steel is immersed in molten zinc to form a strong, tightly bonded coating that resists oxidation and corrosion. The galvanizing layer ranges from 60g/m² to 275g/m², ensuring long-lasting protection even in demanding environments.
Dx51D belongs to the EN 10346 standard for cold forming steel. It features:
Yield Strength: 240–380 MPa
Tensile Strength: 270–500 MPa
Elongation: ≥22%
Thickness: 0.12mm to 6.00mm
Width: 600mm to 1500mm (customizable)
Uniform Zinc Coating: Provides consistent protection across the entire surface.
Strong Corrosion Resistance: Excellent for outdoor and industrial applications.
Good Formability: Suitable for bending, stamping, and shaping in cold-forming operations.
High Surface Quality: Available in multiple finishes for different aesthetic and functional uses.
Versatile Grades Available: Includes DX51D, DX52D, DX53D, S220GD, S250GD, SGCC, SGHC, and more.
