AZ - Hot dip aluminum zinc alloy substrate

The important performance of color steel plate selection.

Most people in the market believe that the complete description of color steel plate is two: thickness and color. For example, 0.5 white gray and other factors are not important.

In fact, color steel plates should be described from five aspects:

1. Mechanical properties of the substrate (yield strength, tensile strength)

2. The performance of the substrate (galvanizing, aluminum zinc plating, weight of the coating)

3. Performance of surface coating (film thickness, impact, salt spray resistance)

4. Surface quality (gloss, color, coating fineness)

5. Other performance indicators (specifications, plate type, tolerances)
