Zinc-aluminum-magnesium cable tray
Material composition: Zinc-aluminum-magnesium alloy coating is formed by taking zinc as the main component, adding about 5-11% aluminum, about 2-3% magnesium and trace elements such as silicon. The substrate is generally steel (such as Q355, etc.).
- Product features
- Strong corrosion resistance: The coating can form a dense protective film, has excellent salt spray, damp heat, acid and alkali corrosion resistance, the service life can reach 2-5 times that of ordinary galvanizing, and the cut and edge parts have self-repair ability.
- Good rust prevention performance: It is not easy to oxidize and rust, the surface color is stable, and it can maintain a good state even after long-term exposure to a humid environment.
- Crack resistance and impact resistance: The alloy has good ductility and adhesion, is not easy to crack or delaminate during processing, has both strength and toughness, and can withstand the stress test during transportation and installation.
- Lightweight: Using thin-walled high-strength steel plus zinc-aluminum-magnesium coating reduces weight and lowers the load of photovoltaic brackets.
- Suitable for photovoltaic needs: Open or ladder designs are available to facilitate heat dissipation of cables, and low-reflection treatment on the surface avoids affecting the efficiency of photovoltaic panels.
- Structural design: Overall bending forming reduces welding points to avoid damaging the coating, and drain holes are designed to prevent accumulated water from causing corrosion.
- Application scenarios: Mainly used in photovoltaic power stations to support DC side and AC side cables; also suitable for harsh environment areas such as coastal areas, high humidity, industrial pollution, etc., as well as photovoltaic building integration (BIPV) systems and so on.
- Installation and maintenance: Choose weld-free assembly design (such as bolt connection), which is easy to install; maintenance: due to its good corrosion resistance, frequent maintenance is not required.
- Service life: up to more than 30 years.
- Cost-effectiveness: The initial cost is slightly higher than that of ordinary cable trays, but the comprehensive maintenance cost is low.
