Product Description
Product Overview
Cable trunkings are non-perforated cable trays designed for superior sealing performance. Once secured with the trunking cover, the interior forms an isolated enclosure that protects cables from rainwater, environmental contaminants, and intrusion. Compared to perforated alternatives, cable trunkings provide exceptional reliability for outdoor installations.
Standard units include limited slots on side plates for streamlined connections. Supported by precision laser cutting technology, customized perforation patterns, arrangements, and specific profiles can be engineered to fulfill exact structural demands.

Key Features
Forms a dense oxide film with self-repairing properties, resisting humidity, acids, alkalis, and industrial salts.
Hardened zinc layer withstands friction, surface impact, and operational wear throughout extensive use.
Uniform, high-gloss silver-white surface finish resistant to fading and chromatic degradation over time.
High plasticity ensures that galvanized layers do not peel, flake, or crack during cutting and modification.
Low production overhead and robust lifecycle stability yield substantial reductions in long-term operational costs.
Manufactured using eco-conscious methods with zero toxic emissions generated throughout service life.
Common Parameters
Anti-corrosion ratings align with zinc thickness: 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, 65μm, with options exceeding 65μm via custom orders.
Standard dimensions available: 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, and 800mm.
Standard profiles engineered at 50mm, 60mm, 100mm, and 150mm heights.
Trough body and cover plate thickness match engineering load limits (e.g., width < 300mm uses ≥ 1.2mm body / ≥ 1.0mm cover; 300mm ≤ width < 500mm uses ≥ 1.5mm body / ≥ 1.2mm cover).
Available in modular sections of 2m, 3m, 4m, and 6m, alongside project-specific continuous lengths.
Application Scenarios
Widely deployed across construction, power distribution, telecommunications, petrochemical, and metallurgical sectors for comprehensive cable protection. Primary installations include electrical shafts, building corridors, basements, production workshops, transformer substations, and industrial distribution units.
