How much difference is there between ladder trays and cable trays
A cable ladder is built for strength, ventilation, and long-span support. Explore the key differences between a cable ladder and cable tray. This guide explains the differences in. A cable tray consists of a single sheet of metal, typically galvanised steel, fitted together with slot patterns, bolts and other fixings. The standard design and robust support allow for the placement and guiding of heavy cables, while the perforations make it easy to clip cables and hold them in. Deciding on using a cable tray or a cable ladder is one of the most significant decisions in construction work. Both systems hold wires, but they do not operate in the same way. A cable ladder has a range of straight lengths and different shaped fittings designed to facilitate changing cabling directions or levels easily, without the need to modify any components.
