Pre-galvanized cable tray is fabricated directly from pre-galvanized steel coil or sheet. It is an economical choice for factories, buildings and indoor cable routes that need basic corrosion protection without a coloured coating.
Pre-galvanized cable tray applications
Pre-galvanized cable tray is suitable for factories, warehouses and indoor technical floors. When ordering pre-galvanized cable tray, check the base-steel thickness and zinc coating stated by the sheet manufacturer. The price of pre-galvanized cable tray is determined by its dimensions, cover, accessories and order quantity.

Material used for pre-galvanized cable trays
The Sun commonly uses Hoa Sen pre-galvanized sheet; the thickness and zinc-coating mass are determined from the certificate and manufacturer declaration for each material batch. Because the zinc layer is applied before cutting and punching, cut edges and fabricated holes require appropriate control during production and storage.
- Bright surface with no additional painting process required.
- Cost-effective with a short production lead time.
- Suitable for indoor cable routes in dry, well-ventilated environments.
- It should not be assumed equivalent to post-fabrication hot-dip galvanizing.
Applications and limitations
The product is commonly used in factories, warehouses, shopping centres and technical floors. For outdoor routes exposed to rain, chemical environments or coastal locations, specify hot-dip galvanized steel, stainless steel or another protective system approved by the project engineer.

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.
