1. Introduction to Cable Trunking
Cable trunking—also called electrical trunking, cable duct or metal trunking—is essential for construction, residential and industrial electrical systems. Its practical design protects and manages wiring neatly, safely and attractively.
The Sun manufactures trunking in pre-galvanized steel, powder-coated steel, hot-dip galvanized steel, stainless steel and aluminium alloy for varied environments and technical requirements.
Other names for cable trunking
- Electrical trunking: a common name emphasizing its role in containing and protecting electrical conductors.
- Trunking: a technical term referring to its channel-shaped route for cables.
- Cable duct: another commonly used description for the same cable-management product.
Terminology differs by region and manufacturer, but these names refer to the same product. Select by material, dimensions, shape and project requirement.
2. Why Use Cable Trunking?
- Safety: reduces the risk of cable damage and electrical incidents.
- Appearance: conceals exposed wiring for a cleaner installation.
- Easy installation and maintenance: wiring can be added or replaced efficiently.
- Durability: suitable materials resist corrosion and weather exposure.
3. Common Cable Trunking Types
3.1 Powder-Coated Cable Trunking
Benefits: corrosion resistance, good load capacity, colour choices and cost effectiveness. Applications: buildings, factories and retail centres.
3.2 Pre-Galvanized Steel Cable Trunking
Benefits: economical, easy to fabricate and moderately corrosion-resistant. Applications: dry, low-humidity and low-chemical environments.
3.3 Hot-Dip Galvanized Cable Trunking
Benefits: excellent durability, corrosion resistance and service life. Applications: outdoor, coastal, chemical and demanding environments.
3.4 Stainless Steel 304 Cable Trunking
Benefits: high corrosion resistance, hygienic and easy to clean. Applications: food, chemical and medical facilities.
3.5 Aluminium-Alloy Cable Trunking
Benefits: lightweight, durable and suitable for premium or non-magnetic installations. Applications: high-rise buildings, data centres and fire-sensitive projects.
3.6 ZAM-Coated Steel Cable Trunking
ZAM zinc-aluminium-magnesium steel offers enhanced corrosion resistance and a protective effect at cut edges. It is well suited to solar, data-centre, outdoor and near-coastal projects, and can be an economical long-term alternative for selected conditions.
