When pure, aluminum is soft and ductile. However, most commercial uses require greater strength than pure aluminum affords. Ventilated cable tray systems are commonly fabricated from a corrosion-resistant metal or from a metal with a corrosion-resistant finish. The selection of the proper material is essentially an economic consideration. It is used in a range of applications with sp nch runs from the main cable tray system to electr cal devices or other equipment. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned in this technical guide only apply to our own cable management ranges and cannot under any circumstances be transposed to si osure, overheating or. Aluminum, fiberglass, steel, and stainless steel are all readily available materials for cable tray manufacturing. Unlike conduit systems, cable trays allow cables to be laid in bundles, improving accessibility, heat. Cable trays are a big part of that.
