How much zinc coating is there on the cable tray
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. 065. The galvanization process is the primary anti-corrosion treatment for cable trays. The quality of the zinc coating directly determines the tray's service life and application scenarios. A cathodic action occurs on cut s leaned and roughened in order to achieve a good bond. Legrand wiremesh cable trays are resistant. Both pre-galvanized cable tray and hot-dip galvanized (HDG) cable tray are the two common types of cable trays, and they are essential components in electrical wiring systems, designed to support and route cables in industrial and commercial buildings. ZM is a metallic coating applied to steel which is made up of a chemical composition which includes Zinc, Magnesium and. Cable tray shall be fabricated either from corrosion resistant metal such as aluminum alloy or carbon steel with corrosion resistant coating such as zinc coatings as specified in the data schedule.
