Why HQ Mount Chooses Zn-Al-Mg Coated Steel for Ground Mounts – Better Corrosion Protection, Longer Life
At HQ Mount, we don't compromise on quality. That's why we use ZAM (Zn-Al-Mg) coated steel for our ground mount systems.
Why ZAM outperforms traditional HDG:
2-6x better corrosion resistance – SGS tested 4,000+ hours salt spray
Self‑repairing cut edges – magnesium migrates to protect scratches and cuts
Multiple coating options – ZAM 310 (25μm) for standard projects, ZAM 430 (35μm) for C5 coastal environments
Guaranteed by leading mills – sourced from Jiusteel with full certification
Proven worldwide – deployed on projects across diverse climates, with excellent customer feedback
30+ year lifespan
