Home / Standard for Hot-Dip Galvanizing of Cable Trays
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. Other common options are: Continuous (pre-galvanized) coatings - often called Sendzimir or pre-galvanized. A cathodic action occurs on cut s leaned and roughened in order to achieve a good bond. After the dipping process, the surplus zinc is blown off and one obtains an extra passivating coat (an ultra-thin.
