Their cross-sectional forms are mostly U-shaped or L-shaped, and their thickness is classified into three categories (2. 5mm, 3mm, and 4mm) based on load levels. The standard length matches the width of the cable tray, with common specifications including 300mm, 400mm, and 500mm. Galvanized crossarms for cable trays are typically made of Q235 low-carbon steel via rolling. Additionally, our association with the country's leading utility engineers has given us a unique background in the. A cable tray system is an assembly of metallic cable tray sections and accessories, that forms a rigid structural system to support cables. As technology advances, so too does the need for effective support systems. Today, plants and buildings are moving more and more towards automation. Cable tray systems are defined to include, but are not limited to straight sections of.
