Wiremesh cable trays are made out of steel wires of higher strength. The trays are manufactured by welding wires and creating a net. The net is further fabricated to form a channel followed by finishing process.
The main advantage of wiremesh cable trays is its cooling characteristics. The open structure of wire mesh cable trays allows free flow of air from all sides and thus help installed cables to stay cool. Since it is open from all sides, it does not accumulate dust and so is easy to clean.
