Every electrical contractor knows the trough tray. It is simple. It is reliable. It works for almost any application. Our Trough Type Cable Tray follows this classic design. The bottom is flat. The sides are bent upward. A separate cover sits on top. The inside has rounded corners to protect cable insulation. The tray is strong and stable. It provides complete enclosure for your cables. This is the standard choice for most building projects.
Solid Construction at a Practical Price
We build this tray with quality materials. The bottom is made from a single piece of steel. No seams. No weak points. The sides are folded for added strength. The cover fits securely on top. The tray carries the load without bending. We test every batch for deflection. Under full load, the deflection stays under 1/200 of the span. This meets the standard requirements. The tray is available in standard widths from 50mm to 1200mm. Heights range from 25mm to 200mm. Standard length is 2000mm. We can also make longer sections if needed.
Choice of Materials for Your Application
The Trough Type Cable Tray comes in multiple materials. Q235 steel with powder coating is the most popular indoor choice. The coating is 60μm thick. It resists dust and looks professional. For outdoor or damp areas, we recommend hot-dip galvanized steel. The zinc layer is 65μm or thicker. It passes 480 hours of salt spray testing. For the highest corrosion resistance, choose stainless steel. 304 is suitable for most wet areas. 316 is better for coastal or chemical environments. Aluminum is also available. All accessories match the tray material. Splice plates, bends, tees, and brackets are all made to the same standard. Our 2-year warranty covers everything.
