3.Product Feature And Application

Lightweight and high-strength structure

Adopting high-quality aluminum alloys such as 6063-T5 and 5083-H111, the weight is only 1/3 of that of steel bridges, and the tensile strength is more than 200MPa. It supports large-span installation (up to 6 meters) and reduces the cost of brackets.

Excellent corrosion resistance

Anodized surface treatment (film thickness 15-25μm), salt spray resistance test over 3000 hours, suitable for coastal, chemical and other highly corrosive environments, lifespan up to 30 years.

Modular fast installation

Standardized snap-on connection design, no welding required, supports horizontal/vertical multi-directional expansion, saving more than 40% installation time.

Fireproof and electromagnetic shielding

Optional fireproof coating (temperature resistance ≥1000℃) or conductive oxidation treatment (resistance <0.1Ω/cm²) to meet fire partition or electromagnetic interference protection requirements.

Environmental protection and energy saving

100% recyclable materials, zero electroplating pollution in the production process, in compliance with RoHS standards.

Application 

1. Power and communication systems

Substation cable laying: electromagnetic interference resistant design to ensure the safety of high-voltage cables.

5G base station cable management: lightweight structure suitable for roof/tower installation, anti-ultraviolet aging.

2.Industry and construction fields

Cable trays for chemical plants: acid and alkali corrosion resistant, protection level IP66, adaptable to high-risk environments.

Commercial complex wiring: hidden buckle design, neat appearance, and fireproof coating.

3. Rail transit and energy

Subway tunnel bridge: excellent seismic performance.

Photovoltaic power station cable bracket: high thermal conductivity, withstanding temperature difference cycle from -40℃ to 120℃.

4. Data center and computer room

Server room wiring: conductive oxide bridge reduces electrostatic interference and supports high-density wiring.

7.FAQ

Q: Will aluminum alloy bridge rust in a humid environment?

A: No! The anodized layer forms a dense oxide film, which isolates water and oxygen from contact. It has passed the 3000-hour salt spray test, far exceeding ordinary galvanized steel frames.

Q: How to solve the load-bearing problem of large-span installation?

A: We provide reinforced rib design or "I"-shaped structure bridge. When the span is 6 meters, it needs to be equipped with a special support arm, and the load can reach up to 800kg/m.

Q: Does it support non-standard size customization?

A: Yes! Provide flexible customization of width, depth, and bending radius.

Q: Is the price of aluminum alloy bridge higher than that of steel products?

A: The initial cost is slightly higher, but it is maintenance-free and has a long life, and the cost of the entire life cycle is reduced by more than 50%.

Q: Can it be mixed with other material bridges?

A: It is recommended to use insulating gaskets to avoid direct contact between aluminum and steel causing electrochemical corrosion.
