Wholesale 300*100 Powder Coated Cable Trunking Manufacturers, Supplier
Product Description
Product Overview
Cable trunkings are non-perforated cable trays designed for superior sealing performance. Once the trunking cover is installed, the interior provides a fully isolated space that shields cables from rainwater, stray animals, and external hazards. This makes cable trunkings a much better choice for outdoor installation compared to perforated cable trays.
Usually, limited slots are provided on the side plates for connections. Supported by precision laser cutting machines, we can deliver a variety of perforated cable tray configurations. Unique perforation shapes and customized arrangements based on cable trunking designs are fully supported to meet specific project requirements.
Key Features
Strong Corrosion Resistance
Forms a dense oxide film with self-repairing capabilities, providing resistance against moisture, acids, alkalis, and salt damage.
Good Wear Resistance
The zinc protective layer offers high hardness and toughness to withstand friction, collision, and surface wear.
Good Aesthetic Property
Presents a uniform, glossy, and bright silver-white finish that does not easily fade or discolor over time.
Excellent Processing Performance
Delivers exceptional plasticity and workability. The galvanized coating remains intact without peeling or cracking during fabrication.
Good Economy
Straightforward production process and extended service life combine to substantially minimize total ownership and replacement costs.
Environmental Friendliness
Minimal emissions generated during manufacturing and zero hazardous substances released during operational life, satisfying clean green standards.
