Tray Sheet Metal Thickness: Typically, the side plates and base plates of cable trays range from 1. It is essential to distinguish between the two main galvanizing processes for cable trays, as their zinc coating ranges and applicable standards differ entirely: Process: Deposits a layer of zinc onto the steel surface through electrolysis. The most deployed type of Sendzimir steel is Z 275 = 275g/m2 (weighed o both sides), this corresponds to 18-20 μm (micron). What are the common thickness standards for galvanized coating of cable tray? When the cable bridge is installed horizontally, if you go to the corner of the wall, according to the Radian of the corner of the wall, you need to bend the cable through a horizontal bend of 45 degrees or 90 degrees. This Galvanized Steel Sheet is obtained by immersing a soft steel sheet in a zinc bath, a stable iron-zinc alloy is formed with a predominance of pure zinc on surface. Carbon steel used for cable trays shall be protected against corrosion by the following processes: Hot-dip galvanized zinc after fabrication in accordance with ASTM A123/A123M, Coating Grade 65 with an average zinc coating weight of 460 g/m2 per side or coating thickness of 0.
