Zinc-aluminum-magnesium photovoltaic cable trays are made from zinc-aluminum-magnesium alloy-coated steel plates, specifically designed for photovoltaic (solar) power generation systems as cable support and protection structures. They offer multiple performance advantages and are suitable for harsh environments such as outdoor photovoltaic power plants.

Material composition: Primarily zinc, with approximately 5-11% aluminum, about 2-3% magnesium, and trace elements such as silicon, forming a zinc-aluminum-magnesium alloy coating. The base material is typically steel (e.g., Q355).

- Product Features

- Strong corrosion resistance: The coating forms a dense protective film, offering excellent resistance to salt spray, humidity, heat, acid, and alkali corrosion. Its lifespan can be 2-5 times or even longer than that of ordinary galvanized coatings, with self-healing capabilities at cut edges and exposed areas.

- Good anti-rust performance: Resistant to oxidation and rusting, with stable surface color, maintaining good condition even in humid environments over long periods.

- Crack and impact resistance: The alloy exhibits good ductility and adhesion, reducing the risk of cracking or delamination during processing. It combines strength and toughness, enabling it to withstand stresses during transportation and installation.

- Lightweight: Utilizes thin-walled high-strength steel with a zinc-aluminum-magnesium coating, reducing weight and lowering the load on photovoltaic mounting structures.

- Adapted to photovoltaic needs: Designed in open or ladder-style configurations to facilitate cable heat dissipation, with low-reflectivity surface treatment to avoid impacting photovoltaic panel efficiency.

- Structural design: Formed through integrated bending to minimize welding points and prevent coating damage, with drainage holes designed to prevent water accumulation and corrosion.

- Applicable scenarios: Primarily used in photovoltaic power plants to support DC and AC side cables; also suitable for harsh environments such as coastal areas, high-humidity regions, industrial pollution zones, and building-integrated photovoltaic (BIPV) systems.

- Installation and maintenance: Preferentially features weld-free assembled designs (e.g., bolted connections) for easy installation; low maintenance costs due to excellent corrosion resistance, requiring minimal frequent upkeep.

- Service life: Can exceed 30 years.

- Cost-effectiveness: Initial costs are slightly higher than those of ordinary cable trays, but lower maintenance costs result in high overall cost efficiency.
