Product Types & Manufacturing Processes
Two Galvanizing Methods
1.Pre-Galvanized Perforated Sheet
Manufactured from pre-coated galvanized steel sheets
Moderate zinc layer thickness with excellent cost-effectiveness
Ideal for standard architectural and decorative uses in normal environments
2.Post-Galvanized Perforated Sheet
Perforated first, then hot-dip galvanized for superior corrosion resistance
Thicker zinc coating ensures long-term durability
Recommended for harsh conditions (e.g., coastal areas, high humidity)
