PRODUCT DESCRIPTION

Galvanized Steel Coil (HDG / GI) – High Strength & Corrosion Protection

Galvanized Steel Coil, also called HDG Steel Coil (Hot-Dip Galvanized) or GI Steel Coil (Galvanized Iron), is produced by immersing steel into a molten zinc bath. This process creates a protective zinc layer that prevents rust and enhances the durability of the steel, making it ideal for applications exposed to moisture, chemicals, and harsh climates.

Our galvanized steel coils are available in Regular Spangle, Zero Spangle, and Minimized Spangle finishes, with post-treatments such as chromating, oiling, and anti-fingerprint (AFP) coating to meet diverse industry requirements.

Galvanized Steel Coil, often referred to as HDG (Hot-Dip Galvanized) or GI (Galvanized Iron), is a type of steel coated with a layer of zinc through the hot-dip galvanizing process. This zinc coating provides superior corrosion resistance, protecting the steel from rust and environmental damage. The thickness of the zinc coating can be customized depending on the intended application, ensuring durability in various environments.


Key Features

  • Superior corrosion resistance – Long-lasting performance in outdoor environments.

  • Versatile applications – Suitable for construction, automotive, appliances, agriculture, and energy sectors.

  • Customizable coating thickness – Ranges from Z30 to Z600 for different durability needs.

  • High formability grades – From DX51D to S550GD, meeting various processing requirements.

Product Specifications

  • Thickness: 0.10–6.0mm

  • Width: 600–1800mm

  • Coating: Z30–Z600

  • Finishes: Regular, Zero, and Minimized Spangle

  • Grades: DX series, S series, and HC series for specialized applications
