Hot-dip galvanized cable tray is fully fabricated before immersion in a bath of molten zinc, forming a protective coating over the surfaces, cut edges and punched holes. It is suitable for outdoor cable routes, factories, substations and areas with high humidity or corrosion risk.

Hot-dip galvanized cable tray performance in outdoor environments
Hot-dip galvanized cable tray is selected for outdoor cable routes and areas exposed to corrosion. When ordering hot-dip galvanized cable tray, specify the steel thickness, load requirement and ASTM A123 coating requirements. The price of hot-dip galvanized cable tray depends on dimensions, covers, fittings and the actual quantity.

Material requirements for hot-dip galvanized cable trays to ASTM A123
The Sun carries out post-fabrication galvanizing and inspects the coating to ASTM A123/A123M when required by the project documentation. Coating thickness depends on the product category and base-steel thickness; one value does not apply to every size.
Steel intended for hot-dip galvanizing must be at least 1.2 mm thick. The 1.2 mm option is used only when width W is below 200 mm; most orders should specify at least 1.5 mm to limit distortion and satisfy the actual load.
- Fabricate tray bodies and fittings before galvanizing.
- Suitable for outdoor installations and humid areas.
- Allow for zinc drainage holes, distortion and post-galvanizing tolerances.
- Additional cuts or drilled holes made on site must receive protective treatment.
Applications
Hot-dip galvanized trays are commonly used in factories, utility infrastructure, substations, solar-power installations and outdoor cable routes. Coastal locations or aggressive chemical environments still require assessment of the corrosion category and design life before selection.
Manufacturing specifications
| Width W | 50–600 mm or as specified |
| Height H | 40–200 mm |
| Thickness T | 0.8–2.5 mm depending on dimensions and cable load |
| Length | 2.5 m; 3 m or as shown on the drawing |
| Construction | Perforated base, with or without a cover, joined by splice plates |
Thickness must be selected according to tray width, cable load, support spacing and installation conditions. An accurate quotation requires confirmation of the tray body, cover, fittings, perforation pattern and quantity.

Frequently asked questions
Does a cable tray require a cover?
A cover is selected according to the required protection against dust and water and the installation location. Prices for an uncovered tray body and a complete tray with cover are listed separately where data is available.
Can the trays be manufactured to drawings?
Yes. The Sun can fabricate dimensions, perforation patterns, lengths and fittings to approved drawings.
How should the thickness be selected?
Selection should be based on width, cable load, support spacing and environment, rather than the lowest price alone.
Order cable tray manufacturing from The Sun
The Sun fabricates straight trays, covers, splice plates, horizontal bends, risers, inside bends, tees, crosses and reducers to drawings. When requesting a quotation, provide W × H × T, length, material, finish, cover requirements, quantity and delivery location.
