Dx51d Sg550 SGCC Hot Dipped Galvanized Steel Sheet Aluzinc Galvalume Coated Gi Gp Galvanized Steel Coil for Duct and Roofing
Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc's characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
Hot-dip galvanizing is the process of applying a protective zinc coating to a steel sheet or iron sheet, to prevent rusting.
Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characteristic of zinc.
Available to select and produce the desired amount of zinc gilded and in particular enables thick zinc layers (maximum 120g/m²).
Classified as either zero spangle or extra smooth depending on whether the sheet undergoes skin pass treatment.

The zinc crystals on the surface of galvanized steel show a pattern of scales or blades. The solid galvanized layer provides excellent corrosion resistance, good welding and cold forming properties. The use of galvanized steel can be divided into general use, roofing, corrugated board building side panel structure, deep drawing and so on.
