Z275 Hot Dipped Galvanized Steel Sheet Q235 Q345 0.09–3.8mm for Structural and Fabrication Applications

1. Product Overview

Hot dipped galvanized steel sheet is produced from galvanized steel coils through cut-to-length processing and is widely used in fabrication and structural applications.

• In practical use, common challenges include:
• Corrosion under humid or outdoor conditions
• Surface condition affecting coating or forming quality
• Dimensional stability influencing fabrication accuracy

2. Technical Solution

The performance of galvanized steel sheet is determined by the combination of base steel and zinc coating layer.

Key characteristics include:

• Zinc coating range: 40–450 g/m²
• Sacrificial corrosion protection mechanism
• Surface treatment improves oxidation resistance and process stability
