A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Galvanized crossarms for cable trays are typically made of Q235 low-carbon steel via rolling. 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. Our cable trays are produced in fit for purpose materials like stainless steel, galvanized, aluminium and fibreglass (FRP/GRP) composites to suit any project type both offshore and onshore.
