Here are the most common materials: Galvanized Steel – Provides high corrosion resistance and durability. Stainless Steel – Ideal for harsh environments with chemical exposure. Aluminum – Lightweight, rust-resistant, and easy to install. Most cable tray systems are fabricated from a corrosion-resistant metal (low-carbon steel, stainless steel or an aluminium alloy) or from a metal with a corrosion-resistant finish (zinc or epoxy). (1) Aluminium: Cable trays fabricated of extruded aluminium are used for their high strength to weight. Before selecting a cable tray, consider the following key factors: Cable Type and Volume: Determine the number and type of cables to be supported. Environmental Conditions: Assess indoor or outdoor usage, exposure to moisture, chemicals, or extreme temperatures. Load Capacity: Choose a tray that. Marlin Steel's wire mesh cable trays are designed for high-performance cable management in data centers, industrial manufacturing, power distribution systems, and commercial infrastructure projects. They also offer the advantages of being light weight (approximately 50% that of a steel tray) and maintenance free, and since aluminium cable trays are non-magnetic, electric ee alloys for marine applications. The selection of material and finish is a function of the environment in wh tant in a wide range of environments, and easily formable (Appendices II and III).
