An aluminum rung type cable tray is a ladder-style cable support extruded from high-strength aluminum alloy, with two side rails connected by evenly spaced transverse rungs. The open ladder geometry gives it an opening rate above 70%, so heat radiates freely from power and control cables and avoids overheating-induced insulation aging. As a non-magnetic metal, aluminum introduces no eddy current losses, and at roughly one-third the weight of an equivalent steel tray it cuts structural load, lifting effort and on-site labor. The material carries a natural oxide layer that resists atmospheric corrosion, requires little maintenance, and is fully recyclable.
We treat the aluminum rung type cable tray as a drawing-based product built around a lightweight material specification. Buyers submit layout drawings that define rung spacing, tray width and depth, and rail profile; we then extrude and fabricate to those exact dimensions rather than forcing a stock rung pitch onto the installation. Because the alloy grade and wall thickness are fixed to the project, the weight-saving benefit stays predictable across the order-engineers can count on lower roof and wall load without over-engineering supports.

Applications
- Data centers run dense, hot cable bundles in limited ceiling space; the over-70% open ladder design ventilates naturally, helping maintain safe current-carrying capacity without adding forced ventilation.
- Retrofit buildings with floor load limits cannot support heavy steel runs; the one-third weight of aluminum reduces structural stress and speeds handling on site.
- Precision instrument workshops and communication base stations are sensitive to electromagnetic interference; the non-magnetic alloy adds no eddy-current heat or distortion to nearby signal circuits.
Customization
We customize rung spacing, tray width and depth, rail profile, mounting hole patterns, surface treatment (anodized or as-extruded), and logos, fabricated to buyer-supplied drawings.
Packaging & Transportation
Units are packed in fumigation-free plywood crates reinforced for international shipping. Trade terms include FOB, EXW and DDP; payment is by T/T.
FAQ
Q: Can rung spacing be matched to my cable bending-radius requirements?
A: Yes. Rung pitch is produced from your installation drawing, so it can be set to suit cable bend radius and cable count.
Q: Is the aluminum tray suitable for coastal or damp indoor locations?
A: Its natural oxide layer resists atmospheric corrosion; for constant salt spray we can discuss additional anodizing or grade options.
Q: What is the order minimum for a custom drawing-based batch?
A: Standard customized products start from 10 units, and complex customized items can be negotiated for single-unit trial orders.
