Cold Rolled Galvanized Steel Sheets

Hot-dip Galvanized Steel Sheet(GI)

This steel sheet is manufactured by pickling and rolling hot coils into full-hard sheets, which are then passed through a pot of molten zinc to be galvanized. Its thick zinc coating ensures enhanced corrosion resistance, making it the most widely used type of galvanized steel.

Applications
  • Home appliances
  • Auto parts
  • Ducts
  • Construction materials
  • Soundproof panels

Electro-Galvanized Steel Sheet(EGI)

Zinc is electroplated onto cold rolled steel sheet (CR) to improve corrosion resistance. Although it has less coating mass than hot-dip galvanized steel sheet, the coating thickness is uniform, the surface is smooth, and the plating at low temperature helps retain the mechanical properties of the base metal.

Applications
  • Home appliances
  • Fire doors
  • Receivers
  • Auto parts

Galvalume Steel Sheet(G/L)

This steel sheet is an aluminum (Al)-zinc (Zn) alloy-coated product with superior corrosion resistance, combining the sacrificial protection and alkali resistance of zinc with the durability, heat resistance, and acid resistance of aluminum in an ideal balance.

Applications
  • Roofing materials
  • Wall cladding
  • Pipes
  • Premium fences
  • Home appliances

Magnesium Alloy Coated Steel Sheet

This steel sheet is hot-dip coated with an optimally blended alloy of aluminum, zinc, magnesium, and silicon. Engineered for superior corrosion resistance, it is suitable for demanding applications in harsh environments.

Applications
  • Roofing materials
  • Wall cladding
