Product Description
High corrosion-resistant ground mounting solution. Made of high-strength carbon steel with Zn-Al-Mg alloy coating, it features self-healing anti-corrosion performance on cut edges, with markedly longer salt spray life than conventional hot-dip galvanized steel of the same thickness (AZ150: over 1,000 h per ASTM B117). High structural strength and deformation resistance for long-term stable operation in high-humidity, high-salt and harsh corrosive environments.

FAQ
Q1: What is the advantage over traditional HDG steel?
A1: Self-healing property on cut edges; AZ150 gives a guaranteed ≥1,000 h salt spray life per ASTM B117, with 1,500 h+ typically measured, markedly better than HDG steel of the same thickness.
Q2: Will on-site cut edges rust?
A2: The alloy forms a dense protective film on cut sections outdoors, inhibiting rust spread and reducing maintenance.
Q3: How long does it last in coastal areas?
A3: Design service life reaches 25+ years in coastal atmospheric corrosion environments.
Q4: Is it compatible with screw pile foundations?
A4: Yes, it supports both concrete pile and screw pile foundations to match different geological conditions.
