Corrugated Cable Tray

Corrugated cable tray is an innovative cable support product formed by integral stamping continuous corrugated reinforcing ribs on steel plates, also named molded cable tray in the industry. Different from ordinary flat-bottom cable trays with simple bending structure, the corrugated structure optimizes the force-bearing mode of the tray body, realizing higher structural rigidity with thinner raw materials, which achieves the dual advantages of light weight and heavy load. Raw material options include cold rolled steel, galvanized steel, stainless steel and SMC fiberglass reinforced plastic, serving for laying, fixing and protecting power cables, control lines and communication cables in construction, industrial, new energy and municipal engineering.

The core competitiveness of corrugated cable tray comes from its unique corrugated forming technology. The whole tray body adopts one-time high-pressure stamping to form continuous horizontal wave ribs on the bottom and side walls. This wave-shaped structure greatly enhances the bending resistance and torsional resistance of the tray, effectively dispersing the pressure generated by stacked cables. Under the same plate thickness, its bearing capacity is more than 30% higher than traditional flat cable trays; manufacturers can use thinner steel plates to produce qualified products, saving nearly 40% metal raw materials and reducing the overall weight of the tray, which lowers transportation and hoisting costs for engineering projects. There is no welding seam on the integrated molded tray body, avoiding hidden troubles such as welding crack rust and uneven flatness of welded cable trays. The rounded transition of corrugations eliminates sharp burrs to prevent scratching cable insulation during wiring construction.

Multiple materials and surface treatment schemes adapt to various harsh working environments. Metal corrugated cable trays can be processed with electro-galvanizing, hot-dip galvanizing, powder coating and fluorocarbon spraying. The dense protective layer significantly improves salt spray resistance and anti-rust performance, applicable to coastal areas, chemical workshops, underground pipe corridors and humid basements. SMC fiberglass corrugated cable trays are formed by high temperature compression molding, with outstanding insulation, acid and alkali corrosion resistance, flame retardant and aging resistance, which are the preferred wiring accessories for petrochemical plants, power substations and new energy charging stations requiring electrical isolation. The corrugated gaps at the bottom form natural heat dissipation channels, accelerating air circulation under cables, reducing cable operating temperature and extending the service life of wires.

A complete set of matching accessories supports full-system wiring layout, including straight sections, horizontal elbows, vertical elbows, tees, crosses, reducing sections, partition plates and matching cover plates. Modular standardized design enables fast on-site splicing only with connecting bolts, greatly shortening construction cycles and reducing labor costs. Anti-slip texture can be stamped on the surface as required to improve safety for overhead installation and daily maintenance. Meanwhile, the corrugated structure has good shock absorption performance, suitable for factories with vibrating equipment, subway tunnels and other vibration-prone scenarios.

Corrugated cable trays are widely used in photovoltaic power stations, data centers, subway comprehensive pipe galleries, commercial buildings, hospitals, chemical plants, automobile manufacturing workshops and energy storage projects. All products comply with national and international engineering standards for load capacity, fire resistance and corrosion resistance. Our factory supports customized widths from 50mm to 1000mm, customized lengths and special non-standard sizes according to customer construction drawings, and provides OEM processing services. Strict quality inspections including load deflection test, salt spray test and flatness detection are carried out for each batch of finished products to ensure long-term stable operation of the cable transmission system.
