China-Africa span cable trays are large-span, high-load-capacity cable support systems available in steel, aluminum, stainless steel, and FRP, with customizable dimensions and certified for global standards. Materials and ConstructionChina-Africa span cable trays are manufactured using galvanized steel, hot-dipped zinc steel, stainless steel (AISI 304/316/316L), aluminum, and fiberglass reinforced plastic (FRP), providing options for corrosion resistance and mechanical strength. Steel trays are often roll-formed to enhance mechanical properties, allowing lighter gauge steel to carry heavy loads while maintaining structural integrity.

Stainless steel trays are welded with matching stainless steel wire to ensure uniform corrosion resistance.

Dimensions and Customization

These cable trays offer flexible customization: widths from 30 mm to 1200 mm, thicknesses from 3 mm to 8 mm, and various colors according to project requirements. Long-span designs allow larger support spans than ordinary trays, reducing the number of intermediate supports and enabling efficient routing over long distances. Trays can be configured as wire mesh, perforated, ladder, trough, or combined types to suit different cable layouts.

Load Capacity and Structural FeaturesLong-span cable trays are engineered for high load-bearing capacity and mechanical durability, suitable for industrial, mining, petrochemical, textile, metallurgy, electric power, and communication sectors. They can accommodate large numbers of branch lines and are designed for overhead or underground installations, including subways and civil defense projects. The structural design ensures minimal maintenance and long-term reliability.

Certifications and Compliance

These cable trays are certified for CCC, RoHS, ISO, CE, NEMA, UL, and SGS, ensuring compliance with international safety and quality standards. Anti-corrosion treatments include hot-dip galvanizing and electrostatic spraying, making them suitable for harsh environments. ApplicationsChina-Africa span cable trays are widely used in building construction, water power plants, industrial facilities, malls, railway and metro stations, airports, solar and thermal power plants, and other large-scale infrastructure projects.

They are ideal for long-distance cable routing where high load capacity and structural durability are required. Additional FeaturesOEM/ODM services for project-specific designs Fast delivery with high production capacity (up to 40,000 meters/day) and optional pre-shipment inspection Minimal maintenance due to robust materials and coatings Traceability with numbered side rails, rungs, and splice plates for quality assurance These specifications make China-Africa span cable trays a reliable choice for large-scale, high-load, and long-span cable management projects.
