What Is a Cable Tray? Finishes, Sizes, and Standards Explained
A cable tray is a rigid support system for routing electrical cables, not an airflow product, even though it sits in Goodwind's ductwork accessories line. Here are the finishes, sizes, and standards it's available in.
A cable tray is a rigid support system used to route and secure electrical cables, typically installed along walls, ceilings, or under raised floors in commercial and industrial buildings. Unlike the rest of Goodwind's ductwork accessories, a cable tray doesn't carry air. It's an electrical cable management product, grouped with items like plenum boxes and access doors in Goodwind's accessories range rather than sold as a standalone electrical line.
What Is a Cable Tray?
A cable tray is an open or perforated channel that holds cables in place as they run through a building, instead of leaving them loose or bundled by hand. Goodwind's cable tray (model GT-CT) is built for that structural role: supporting cable weight over a run, protecting cables from physical damage, and giving an electrician a clear, accessible layout for maintenance or future additions.
Finishes Available
| Finish | Standard |
|---|---|
| Hot-dip galvanized | IS 10748 / IS 2629 |
| Pre-galvanized sheet | IS 277 |
| Powder-coated | IS 101 |
| Stainless steel 304 | N/A |
| Stainless steel 316 | N/A |
| Commercial-grade aluminium | N/A |
The right finish depends mostly on where the tray is installed and how much corrosion exposure it will see over its life. Hot-dip galvanized trays tend to hold up well outdoors or in damp plant rooms. Powder-coated and stainless steel options suit indoor commercial spaces where appearance matters alongside durability.
Sizes
| Dimension | Range |
|---|---|
| Height | 25 mm to 125 mm |
| Width | 100 mm to 1000 mm |
| Thickness | 10, 12, 14, 16, or 18 SWG |
Height, width, and thickness are confirmed per project rather than fixed to a single standard size, since cable load and run length vary from one installation to the next.
Where Cable Trays Are Used
Cable trays go into commercial, industrial, and residential electrical installations wherever cables need to run a distance and stay organized and accessible. That covers a factory floor's power distribution as easily as the cable runs above a false ceiling in an office fit-out. As a cable tray manufacturer, Goodwind builds each of the finishes above to the size range listed, quoted against a project's run length and cable load rather than sold off a fixed catalog size.
Frequently Asked Questions

A cable tray is a rigid support system that holds and routes electrical cables through a building, keeping them organized and protected instead of running loose.
What finishes does Goodwind's cable tray come in?

What sizes are available?
Heights from 25 mm to 125 mm, widths from 100 mm to 1000 mm, and thickness options of 10, 12, 14, 16, or 18 SWG.
Is a cable tray part of an HVAC system?
No. It's an electrical cable management product. Goodwind groups it with its ductwork accessories because it's part of the same product range, not because it moves air.
