Description
SGCC is the hot-dip galvanized steel sheet with the zinc coating thickness of 5–20 μm. It offers better corrosion resistance than cold-rolled steel, but welding can generate zinc fumes, thus requiring proper ventilation measures.
Key Features
1. Excellent corrosion resistance (the zinc layer provides cathodic protection)
2. Low-cost rust prevention (no additional coating required)
3. Good workability (meet general forming requirements)
4. Zinc layer passivation (further improve corrosion resistance)
