Frequently Asked Questions
- Q: What makes ZAM coating different from GI and GL?
- A: ZAM coating contains magnesium in addition to zinc and aluminum. The magnesium addition promotes the formation of a stable, dense protective film that significantly enhances corrosion resistance, particularly at cut-edges and scratches, providing a self-healing effect.
- Q: Is ZAM coated steel suitable for extreme weather conditions?
- A: Yes. ZAM coated steel offers excellent performance in both humid and aggressive environments. Its superior corrosion resistance makes it ideal for applications in coastal, industrial, and high-humidity areas.
- Q: Can ZAM coated steel be used as a substrate for PPGI?
- A: Yes. ZAM coated steel provides an excellent substrate for color coating. Our prepainted ZAM products combine the superior corrosion resistance of ZAM with the aesthetic and protective benefits of high-quality paints.
