Powder Coated Cable Tray
Our steel tray systems — perforated, ladder and solid-bottom trough — finished with an electrostatically applied epoxy resin powder coat on our own spray line. Powder coating is the finish buyers choose for buildings that face fire-service acceptance, for color-coded cable routes, and for interiors where the tray stays visible: residential and commercial buildings, factories, basements, and power and lighting installations.

Why buyers specify it
- Epoxy resin powder, electrostatically sprayed and cured on our own spray line — the coating wraps edges and corners that liquid paint misses
- The fire-rated build for acceptance projects: powder-coated tray is the standard specification where a project goes through fire-service inspection — buildings, basements, strong- and weak-current routes
- Color is functional, not decoration: routes can be color-coded by system (power vs. data vs. fire alarm), and architectural colors keep exposed tray in order in finished interiors — custom colors from the catalog palette
- A sealed barrier over the steel substrate: no zinc runoff staining, no white rust blooms on indoor runs, and a smooth surface that wipes clean in hospitals, malls and plant rooms
Specifications
| Coating | Epoxy resin powder, electrostatic spray application, cured |
|---|---|
| Colors | Standard production colors · custom colors on request (color customizable per the catalog note) |
| Covers | Matching powder-coated covers in the same color batch |
| Positioning | Fire-resistant builds for projects with fire-acceptance requirements (buildings, basements, strong- and weak-current routes) |
| Use it where | Buildings · basements · color-coded power / data / fire-alarm routes · visible interiors |
| Trade-off & limit | Powder coat is a finish, not a structure: sizes and SWL still follow the base steel system tables. Suitability for outdoor heavy-corrosion duty is not stated in the catalog — confirmed with your quotation |
Ranges from the Hongfeng product catalog parameter tables. Exact model tables (SWL / weight per size) are sent with your quotation.
Load & installation conditions
The powder coat adds a finish, not a structural change: sizes and safe working loads follow the same catalog parameter tables as the base steel system, and the quotation cites the table row for the size quoted.
Custom & supply
Coated orders are sprayed to order so straights, fittings and covers come off the line in one color batch. If your project requires specific fire-performance documentation, confirm the requirement with us before material selection — we will tell you exactly which documents apply to the build quoted.
Fittings in the same coat
Every bend, tee, cross, reducer and cover for a powder-coated order goes through the same spray line in the same color batch as the straights — no galvanized fitting standing out in a coated run. Splice plates and small hardware are supplied finished to match, and the full count is packed into the same shipment.
Where it is used
Buildings & basements
Residential and commercial buildings, factories and basements facing fire-service acceptance.
Color-coded routes
Power vs. data vs. fire-alarm routes distinguished by color, and architectural colors for finished interiors.
Strong- & weak-current routes
Power and lighting installations where the tray stays visible and must read as finished work.
Not a structural upgrade
The coat adds a finish, not strength: sizes and SWL follow the base steel system tables, and outdoor heavy-corrosion suitability is confirmed with your quotation.

Frequently asked questions
What do I choose for a dry indoor environment?
Pre-galvanized (40 / 80 / 275 g/m²) or electro-galvanized (8–25 µm) is enough — with the known limit that cut-edge protection is thinner than the flat faces.
What do I choose for outdoor or coastal duty?
Hot-dip galvanized 45 / 65 / 85 µm (65–85 µm is the usual outdoor and coastal specification), or stainless 304 / 316, aluminum, or ZAM for photovoltaic, communications and railway projects.
What do I choose for chemical or wastewater atmospheres?
FRP (corrosion-proof, electrically insulating), stainless steel (grade per project specification) or polymer — and note that metal load tables do not transfer directly to FRP, so FRP selection is confirmed with your quotation.
How are color and cover matching decided?
Powder-coat color is customizable per the catalog note; cover material match, MOQ and custom lead time are all confirmed with your quotation.
