The zinc-aluminum-magnesium coated solar metal roof bracket is specially designed for metal roofs such as upright lock edges, corrugated panels, and trapezoidal panels. It adopts innovative zinc-aluminum-magnesium alloy coating (Zn+5-11%Al+2-3%Mg), forming a dense protective layer through advanced continuous hot-dip coating processes. This coating features unique self-healing properties and resists extreme corrosive environments like acid rain, salt spray, and industrial pollution. Ideal for high humidity, coastal areas, and chemical plants, the system supports 5°~35° tilt adjustment and is compatible with all mainstream solar panel models.
