First of all, let's talk about the purpose and purpose. They are both the same, and the ultimate purpose of cable supports and cable trays is to lay cables.
Cables are laid in cable trenches and tunnels, usually fixed with brackets. Commonly used brackets include angle steel brackets and prefabricated brackets.
Cable trays are divided into slot type, tray type, ladder type, and grid type structures, consisting of brackets, brackets, and installation accessories. The bridge in the building can be erected independently or laid on various buildings (structures) and pipe rack supports
However, the usage environment is different. Cable supports are usually used in underground pipe galleries, cable trenches, and tunnels. The recommended span for such projects is generally around 0.8m or 1m. When the cable span distance is large, cable trays are needed. Generally, cable trays are used in ordinary residential, public, industrial, and steel structure construction projects. The usual length of cable trays is 2 meters, and large span cable trays can reach more than 3-6 meters.
The span length of the bridge has increased, and the load capacity of the natural bridge is higher than that of the cable support.
As for the materials, both cable supports and cable trays can be made of steel, fiberglass, or composite materials to meet different anti-corrosion needs.
