FAQ

 

FAQ 1: Why is Zn-Al-Mg coating superior for weatherproof solar mounting brackets?

A: Zn-Al-Mg coatings combine zinc, aluminum, and magnesium to form a self-healing protective layer that resists corrosion 4-20 times longer than traditional galvanized steel . The magnesium (Mg) stabilizes the pH of surface electrolytes, preventing rust-inducing reactions, while aluminum (Al) enhances adhesion and creates dense corrosion products like Simonkolleite and layered double hydroxides (LDH). This synergy ensures durability in coastal, high-humidity, and industrial environments .

FAQ 2: How does the design protect against extreme weather (e.g., rain, UV, salt spray)?

A: The coating's ternary eutectic microstructure (Zn/Mg Zn2/Al phases) forms a barrier against moisture and UV degradation. In salt spray tests, Zn-Al-Mg brackets withstand 6,000+ hours without red rust (vs. 500-1,000 hours for standard galvanized steel) . The LDH layer also blocks chloride ion penetration, critical for coastal installations .

FAQ 3: Are these brackets compatible with all tile types (clay, concrete, slate)?

A: Yes. The system uses adjustable clamps and non-penetrating hooks that slide beneath tiles without drilling, preserving roof integrity. Pre-drilled holes and corrosion-resistant stainless steel fasteners (e.g., M8 bolts) ensure compatibility with clay, concrete, and slate tiles .

FAQ 4: What certifications validate their structural and safety performance?

A: Brackets comply with UL 2703 (safety for solar mounting systems) and ISO 9001 (quality management) . Wind load testing confirms stability at 216 km/h (60 m/s), while snow load capacity reaches 2.4 kN/m² . Third-party labs verify corrosion resistance per ASTM B117 standards .

FAQ 5: What is the expected lifespan and warranty coverage?

A: The Zn-Al-Mg coating ensures a 25+ year service life, with manufacturers offering a 15-year product warranty . The self-repairing coating maintains performance even if scratched, as Mg-rich phases oxidize to seal micro-cracks .
