2013 Cable Tray Thickness

The 2013 standard specifies steel cable tray thickness from 1. 0 mm to 2. 2 mm, aluminum alloy from 1.

2 mm to 2. 5 mm, and glass-fiber reinforced trays from 3. 0 mm to 5.

0 mm. According to the 2013 standard, the maximum thickness of steel cable tray plates is 2. 2 mm, while the minimum thickness is 1.

0 mm. For aluminum alloy bridge plates, the maximum thickness is 2. 5 mm and the minimum is 1.

2 mm. Glass-fiber reinforced (FRP) bridge plates have a maximum thickness of 5. 0 mm and a minimum of 3.

0 mm. These values are widely adopted by major cable tray manufacturers for compliance and structural integrity in electrical installations.

Material Considerations

Steel trays: Commonly used for heavy-duty applications due to high mechanical strength and durability. Thickness selection depends on load requirements and environmental conditions. Aluminum trays: Lightweight and corrosion-resistant, suitable for moderate loads and environments where weight reduction is important.

Glass-fiber reinforced trays: Ideal for highly corrosive environments, chemical plants, or outdoor installations where steel or aluminum may degrade over time.

Practical Implications

Choosing the correct thickness ensures structural stability, safety, and compliance with electrical codes. Thicker trays provide higher load capacity but increase weight and cost, while thinner trays are lighter but may be limited to light-duty applications. Always consider tray type, span, and cable load when selecting thickness.

These 2013 standard thicknesses serve as a benchmark for design, procurement, and installation of cable tray systems in industrial, commercial, and utility projects.
