The arm support is the main component that supports the cable trays and cables. It is composed of columns, column bases, and arm supports. It has the advantages of simple structure, light weight, low cost, high strength, and beautiful appearance. It can meet the needs of installation in different environmental conditions (such as on process piping frames, under floor slabs, on walls, and in cable trenches) in various forms (suspended, upright, side wall, single-sided, multi-sided, and multi-layer).

When cable trays are required for multiple layers with heavy loads, it is best to adopt a bilateral installation to avoid excessive unbalanced loads.

The surface treatment of the support arm part includes four types: electroplated zinc, hot-dip zinc, spray painting, and spray plastic coating.
