Product Description
Hot Dipped SGCC Dx51d G60 G90 Z60 Z80 Z100 Z120 Z275 Zinc Coated Galvanized Steel Coil
Hot Dipped Galvanized Steel Sheet in Coil (GI) is manufactured by processing Full Hard sheet through acid washing, rolling, and zinc bath immersion to apply a protective zinc coating. This process delivers exceptional corrosion resistance, superior paint adhesion, and excellent workability due to zinc's inherent properties. Both hot-dipped galvanized steel sheets and coils share identical processing methods and specifications.

Manufacturing Process
The hot dip galvanizing process involves passing steel through a molten zinc bath, creating a strong iron-zinc bonding layer that firmly adheres the zinc coating to the base metal. Our hot-dip galvanized products are manufactured according to strict specifications, while electro-galvanized products comply with relevant industry standards.
Applications
  • Corrugated steel sheet
  • Ceiling channel
  • Industrial refrigeration
  • Cold storage
  • Door panel
  • Sandwich panel
