8. FAQ

Q1: What is the difference between AZ and GI?
AZ is aluminum-zinc coating, GI is pure zinc coating.

Q2: Is AZ more corrosion resistant?
Yes, especially in industrial or high-temperature environments.

Q3: Can it be painted?
Yes, commonly used as pre-painted substrate.

Q4: Is it suitable for structural use?
Mainly used for cladding rather than heavy structural load.
