Cable Tray Construction and Materials
Cable tray by Superior Tray is generally constucted from corrosion-resistant metals or from a metal with a corrosion-resistant finish. Therefore when choosing the cable tray for your specific application the main considerations are; the electrical/grounding properities, mechanical stregth, corrosion properties and economical implications. Each construction material offers a different level of mechanical strength defined by the loading as well as the deflection properties. The corrosion-resistance, electrical and grounding properties as well as the the cost of each type of cable tray also varies based on the construction material, although many materials satisfy the basic necessities, wrought aluminum alloys and low carbon steel provide the most economical solutions.
The specific technical properties for each type of cable tray can be found at the following links:
