Steel Coils

Galvanized Steel Coil (GI)

CR coil hot-dip coated with zinc — the standard corrosion-resistant substrate for construction and appliances.

Product Overview

Hot-dip galvanized coil is produced by immersing cold rolled substrate in a molten zinc bath, forming a metallurgical coating that protects the steel electrochemically. Coating weight is specified in g/m² per side.

Procurement Notes

  • Confirm exact grade, thickness tolerance and coating weight before quotation.
  • Request Mill Test Certificate (MTC) matched to the actual heat number.
  • Clarify packaging (seaworthy, eye-to-sky/eye-to-wall) and inner/outer diameters.
  • Compare suppliers on lead time, port of loading and inspection readiness — not price alone.
