0.15–3.8mm Z40–Z275 Passivated (Chromated) 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 process.
The passivated (chromated) surface treatment improves resistance to white rust during storage and transportation, making it suitable for roofing sheets and construction applications.
2. Technical Solution
Performance is based on:
Zinc coating (Z40–Z275) providing corrosion protection
Chromated passivation layer reducing white rust formation
Uniform coating improving durability
Metallurgical bonding between zinc and steel
