Cable trunkings are non-perforated cable trays designed to provide superior sealing performance. Once the trunking cover is secured, the interior forms an isolated protective environment. This structure effectively protects enclosed cables against rainwater, stray animals, and other external factors, making cable trunkings the preferred solution for outdoor installations compared to standard perforated trays.
Typically, limited slots are incorporated into the side plates of the cable trays to facilitate secure connections. Equipped with advanced laser cutting machinery, diverse perforated configurations can be manufactured based on specific requirements. Customization of hole shapes, layouts, and configurations built upon solid trunking designs is fully supported.

Zinc layer thickness: The anti-corrosion rating of galvanized cable trays depends directly on the thickness of the zinc coating. Available standard thicknesses include 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, and 65μm. Custom specifications exceeding 65μm are available on request.
Width: Standard options include 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, and 800mm.
Height: Common height specifications are 50mm, 60mm, 100mm, and 150mm.
Thickness: Thicknesses for both trough body and cover plates are engineered according to load-bearing requirements. For galvanized steel trays with a width (B) < 300mm, body thickness is typically ≥ 1.2mm with cover ≥ 1.0mm. For 300mm ≤ B < 500mm, body thickness is ≥ 1.5mm and cover ≥ 1.2mm.
Length: Standard lengths are provided in 2m, 3m, 4m, and 6m, with full customization options available.
Cable trunkings are widely deployed across infrastructure projects, power utilities, telecommunications, petrochemical facilities, and metallurgical industries for both indoor and outdoor cable management. Key installations include electrical vertical shafts, service corridors, commercial basements, industrial workshops, and high-voltage power distribution substations.
