Aluminium alloy cable trunking is a lightweight, non-magnetic cable-management solution for containing, protecting and organising power, control and data cables. The Sun manufactures aluminium trunking to project dimensions, thicknesses and drawings, including covers, joints and directional fittings.

1. What is aluminium cable trunking?

It is enclosed, box-shaped trunking fabricated from aluminium alloy sheet. Its low density makes the system substantially lighter than comparable steel trunking.

2. Why use aluminium?

Reduced system weight

It is useful where building load, ceiling supports, handling or installation weight matters.

Non-magnetic material

Aluminium is non-ferromagnetic and can suit telecommunications, electronics and technical applications. Overall electromagnetic performance still depends on the complete system design.

Naturally protective surface

Aluminium develops an oxide layer that provides protection in suitable environments.

Convenient fabrication

It can be cut, punched and formed to project drawings.

3. Suitable applications

Typical applications include data centres, telecommunications, electronics factories, technical areas, buildings with load limits and suitable outdoor installations. Outdoor, coastal and chemical environments require evaluation of alloy, finish and installation conditions.

4. Material and surface considerations

Natural aluminium or specified surface treatments may be used. Prevent galvanic corrosion: where aluminium contacts steel or copper in wet conditions, use isolators, compatible fasteners or another suitable separation method.

5. Technical specifications

Item	Option
Product	Aluminium alloy cable trunking
Form	Enclosed trunking, optional cover
Standard length	2.5 m/length
Width / height	To project requirement
Thickness	Selected by size, load and support spacing
Accessories	Bends, tees, crosses, joints and supports

Common sizes include 100×50, 200×50, 100×100, 200×100, 300×100 and 400×100 mm; custom sizes are available.

6. Selecting thickness

Select thickness from trunking dimensions, cable weight, support spacing and type, route direction, future capacity, transport and installation. Heavy routes require a load and support-spacing design.

7. Comparison with other materials

Material	Main characteristic
Aluminium alloy	Lightweight, non-magnetic, good corrosion resistance
Powder-coated steel	Colour options for dry indoor routes
Pre-galvanised steel	Economical indoor option
Hot-dip galvanised steel	Outdoor and more corrosive conditions
Stainless steel	Clean or demanding corrosion environments

8. Manufacturing and inspection

The Sun follows cutting → punching → press forming → fitting fabrication → inspection → packing. Checks include dimensions, thickness, shape, holes, joints, accessories, surface condition, quantities and packing.

9. Transport, storage and installation

Protect the surface from impact, scratching and contact with dissimilar metals. Keep products dry and use suitable supports and isolation details during installation.

10. Quotation and made-to-order supply

Price depends on alloy, dimensions, thickness, cover, fittings, quantity, drawings and delivery location. Send W×H, thickness, length, accessories, quantity and drawings or a bill of quantities for a factory quotation.
