What type of cable tray is a black cable tray

Black cable trays are typically either wire mesh trays with a black painted finish or rigid black PVC plastic trays, each offering distinct installation and performance characteristics.

Wire Mesh Black Cable Trays

Black wire mesh trays, such as Cablofil Wiremesh Cable Trays, are made of steel with a black painted finish. They are designed for maximum strength with minimal weight, allowing flexible routing in complex configurations. Features include Safe-T-Edge protection to prevent cable fraying, smooth rounded wire to resist dust accumulation, and large mesh openings (2" x 4") for easy cable insertion at any point. These trays are available in standard 10-foot lengths and can be combined with a wide range of accessories for fast installation and on-site fitting adjustments (Cablofil) .

Black Plastic Cable Trays

Black plastic cable trays are typically made from rigid, unplasticised PVC, providing a non-corrodible, lightweight, and cost-effective alternative to metal trays. Examples include Canford and Penn Elcom black plastic trays. Key characteristics include:

• Self-extinguishing and non-flammable for practical safety purposes .
• Slot-punched or solid designs for easy cable management and reduced labor costs.
• Customizable lengths: can be cut with standard tools without leaving sharp edges .
• Dimensions: commonly available in widths from 105mm to 180mm, heights around 17mm, and lengths of 2 meters .
• Lightweight and easy to install, suitable for racks or wall-mounted applications .

Summary

• Wire Mesh Black Tray: Steel, black painted, strong, flexible, ideal for complex routing, dust-resistant, Safe-T-Edge.
• Plastic Black Tray: Rigid PVC, corrosion-resistant, lightweight, self-extinguishing, easy to cut and install, cost-effective. Choosing between these types depends on installation environment, load requirements, fire safety considerations, and ease of modification on-site. Wire mesh trays are preferred for heavy-duty or high-density cable runs, while plastic trays are ideal for lightweight, corrosion-free, and economical installations.
