Are mesh cable trays used in steel structure buildings
Steel wire mesh cable trays are open-grid cable support systems made from formed and welded steel wire. They are commonly used to route and support cables above server racks, along walls, under raised floors, near equipment areas, or throughout industrial and commercial facilities. Unlike traditional formed trays, wire mesh trays rely on distributed wire intersections for strength rather than solid rails or rungs. Far superior to traditional conduit in many applications, cable tray systems offer unparalleled accessibility for maintenance. In the electrical wiring of buildings, a cable tray system is used to support insulated electrical cables used for power distribution, control, and communication.
