Cable trunkings are non-perforated cable trays designed with superior sealing performance. Once the trunking cover is installed, the interior provides a secure, enclosed space that protects cables against rainwater, environmental hazards, stray animals, and other external factors. Compared to standard perforated cable trays, cable trunkings are the preferred choice for reliable outdoor installations.
Standard configurations feature precisely engineered connection slots on the side plates. Equipped with advanced laser cutting machinery, we manufacture diverse perforated and solid-bottom cable systems. Specific perforation patterns, custom layouts, and tailor-made dimensions can be provided according to exact project requirements based on our cable trunking solutions.

Forms a dense protective oxide film with self-repairing capabilities, providing long-lasting resistance against moisture, acids, alkalis, and industrial salts.
The protective zinc layer provides superior hardness and toughness, effectively withstanding physical friction, impact, and mechanical abrasion during handling.
Presents a clean, high-gloss silver-white surface that maintains its visual appeal over time without fading or discolouration.
High structural plasticity ensures smooth fabrication; the zinc coating remains intact without cracking or flaking during cutting and bending.
Combines economical production processes with extended service life, substantially lowering long-term maintenance and replacement expenses.
Produced with minimal environmental emissions and zero hazardous substance release during its operational lifespan, meeting international green standards.
Zinc Layer Thickness: The corrosion protection level corresponds directly to zinc thickness. Available thicknesses include 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, 65μm, and customized coatings exceeding 65μm upon request.
Width Options: Standard widths include 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, 800mm, up to 1000mm.
Side Heights: Standard depths offered are 50mm, 60mm, 100mm, 150mm, and customizable up to 600mm.
Material Thickness: Sized according to load-bearing demands. For steel galvanized trays with width < 300mm, body thickness is typically ≥ 1.2mm, cover plate ≥ 1.0mm. For widths between 300mm and 500mm, body thickness is ≥ 1.5mm, cover plate ≥ 1.2mm.
Standard Length: Standard production lengths are 2m, 3m, 4m, and 6m, with full custom length support up to 10m.
Extensively utilized throughout modern construction, power distribution, telecommunications, petrochemical, and metallurgical sectors for comprehensive cable management. Ideal installation sites include electrical service risers, utility corridors, underground basements, industrial production floors, substations, and control facilities.
