Ladder type cable tray, also called cable ladder, supports cables on rungs set between two side rails. The open design gives the best ventilation of any cable tray type, lets cables enter and leave at any point along the run, and keeps weight low even on long spans, which is why it is the usual choice for heavy power cables, long horizontal and vertical runs, and outdoor routes. It is available in several materials and finishes and can be made to your project size.
Key Features
- Maximum ventilation: the open rungs let heat escape from the cables and keep air moving around them
- Self-draining and dust-resistant: water, dust, and debris pass through instead of collecting in the tray, which suits outdoor and dusty environments
- Strong over long spans: deep side rails carry heavy and large-diameter cables between supports
- Flexible cable entry: cables can be laid in, tied to the rungs, and branched off at any point along the run
- Light and easy to handle: less steel than a solid-base tray of the same width, which simplifies transport and installation
- Complete system: compatible bends, tees, crosses, reducers, and brackets are available
Materials and Finishes
- Hot-dip galvanized steel: for outdoor, humid, and industrial environments
- Galvanized steel: for indoor, dry locations at lower cost
- Sprayed (powder-coated) steel: where color coding or appearance matters
- Aluminum alloy: lightweight and corrosion resistant
- Stainless steel: for severe corrosive environments such as coastal and chemical sites
Ladder Tray or Perforated Tray?
| Ladder Type | Perforated Tray | |
|---|---|---|
| Base | Open rungs | Continuous base with holes |
| Ventilation | Best | Good |
| Cable support | Cables rest on rungs; suits heavy cables over longer spans | Full support along the base; suits smaller and mixed cables |
| Dust and debris | Passes through the rungs | Can collect on the base |
| Best for | Power cables, long runs, outdoor routes | Control, data, and mixed cable routes |
