High-aluminum zinc-aluminum-magnesium

High-aluminum zinc-aluminum-magnesium

New type of highly corrosion-resistant coated steel plate

Zinc aluminum magnesium plate

Corrosion resistance mechanism

A large number of experiments verify that AZM products have excellent corrosion resistance and are the trend in the construction field. The reasons are as follows:

Product advantages

If under the same environment, the lifespan of Al-Zn-Mg steel products (with high aluminium content) can be increased by 1/3 longer than that of galvalume with the same coating, and it is more suitable for the marine and livestock environments.

Ten-week cyclic Q-Fog test (Q-fog CCT)

After 10 weeks of cyclic corrosion comparison experiments, there was no obvious change on the surface of the Al-Zn-Mg samples (AM150 gsm and AM100 gsm), a little red rust appeared on the surface of the galvalume sample (AZ150 gsm), and a large area of rust appeared on the surface of the galvalume sample (AZ100 gsm).

Eleven-month marine environment exposure

After 11 months of marine environment exposure experiments, there was no obvious change on the surface of the PPAM (AM50 gsm) sample, while salt frost appeared locally on the surface of the PPGL (AZ50 gsm)sample.

Fourteen-month outdoor acid rain environment exposure

After 14 months of exposure to outdoor acid rain environment, there was no obvious change on the surface of the Al-Zn-Mg samples (AM150 gsm and AM100 gsm), but the surface of the galvalume sample (AZ150 gsm) began to rust, and the surface of the galvalume sample (AZ100 gsm) had been rusted over a large area.
