Construction Galvanized Steel Sheet Plate , Hot Dipped GI Zinc Coated Steel Sheet

Galvanized Steel Sheet Plate SGCC DX51D Q235B Z275 | Hot Dipped GI Zinc Coated Steel Sheet for Construction

Our galvanized steel sheet and plate are manufactured by passing carbon steel substrate through a molten zinc bath at approximately 450°C in a continuous hot-dip galvanizing line. This process forms a metallurgically bonded zinc coating on the steel surface, providing excellent corrosion resistance and extending service life. With steel grades including SGCC, DX51D, and Q235B, and zinc coating up to Z275, our products are suitable for a wide range of construction and fabrication applications.

• Chromated: Additional anti-corrosion protection during storage and transport

• Oiled: Prevents white rust during shipping and storage

• Anti-fingerprint: Clean surface appearance for visible applications

• Zero Spangle: Smooth surface ideal for painting and precision applications

• Regular Spangle: Classic crystalline appearance for general construction

• Roofing & Construction: Corrugated roofing sheets, wall cladding, ceiling panels, purlins

• Building Materials: Sandwich panels, ventilation ducts, gutters, downspouts

• Home Appliances: Refrigerator back panels, washing machine housings, air conditioner parts

• General Fabrication: Storage racks, shelving, furniture frames, signage

• Automotive: Interior structural parts, underbody components
