0.15–3.8mm G40–G90 (Z100–Z275) Hot Dipped Galvanized Steel Sheet SGCC DX51D for Roofing Applications
1. Product Overview
Hot dipped galvanized steel sheet is produced by coating cold rolled steel with a zinc layer through a hot dip galvanizing process.
G40–G90 coating corresponds to medium to high zinc layer thickness, providing balanced corrosion resistance and cost efficiency for roofing and general construction applications.
2. Technical Solution
Performance is based on:
Zinc coating range G40–G90 (approx. Z100–Z275)
Zinc acting as sacrificial protection layer
Uniform coating improving service life
Surface treatments reducing oxidation and handling marks
