Why HQ Mount Uses Zn-Al-Mg Coated Steel for Ground Mount Designs
At HQ Mount, we engineer solar mounting systems to last. That's why we choose Zn-Al-Mg (ZAM) coated steel – a next‑generation corrosion protection technology that outperforms traditional hot‑dip galvanized (HDG) steel in every critical metric.
1. Superior Anti‑Corrosion Performance
ZAM coating delivers 2–6x better corrosion resistance than standard galvanization. In neutral salt spray tests, standard HDG steel typically shows red rust after approximately 500 hours, while ZAM coatings of the same thickness can withstand 2,000- 3,000 hours – and in some cases exceed 4,000 hours. HQ Mount's ZAM steel brackets have been SGS tested for 4,000 hours, demonstrating exceptional durability even in harsh environments.

2. Self‑Repairing Cut Edges
Unlike traditional galvanized steel, ZAM coating has a unique self‑healing property. When the steel is cut or scratched, magnesium from the coating migrates to the exposed edge, forming a dense protective oxide film. This eliminates the need for post‑cutting treatments and ensures long‑term protection even after fabrication and installation. As a result, the service life of ZAM steel structures can reach 30+ years.
3. Multiple Coating Options for Different Environments
HQ Mount offers ZAM coating layers suited to various environmental conditions:
|
Coating Grade |
Typical Application |
|---|---|
|
ZAM 310 |
Standard solar applications, C4‑C5 corrosive environments |
|
ZAM 430 |
Higher lifetime expectation for C5 coastal and marine environments |
These coatings are suitable for C5 environments – areas with high salinity, high humidity, or aggressive industrial conditions. HQ Mount can provide ZAM 310 or ZAM 430 solutions based on your project's environmental requirements.
4. Guaranteed by Leading Steel Mills
HQ Mount sources ZAM coating steel from reputable mills like Jiusteel, with full material certification and mill test reports. The Zn‑Al‑Mg coating is applied directly by the raw material manufacturer, ensuring better quality control and consistent coating thickness – unlike post‑galvanization processes where quality can vary.
Lifespan Guarantee by Manufacturer (ISO 12944-2)
5. Proven Global Experience
HQ Mount has deployed ZAM coating ground mount systems on projects worldwide, and customer feedback on corrosion performance has been consistently positive. From the 5MW ZAM steel PV bracket project to utility‑scale solar plants, our ZAM solutions have proven their reliability across diverse climates – from coastal to high‑humidity to industrial zones.
