Z275-Z600 Galvalume Steel Plate A792 SAI API Bare Galvalume Sheet

Galvanized Steel Sheet Z275-Z600 As Require High Reflectivity SGLCH A792

Cold galvanized pipe is electric galvanized, galvanized amount is very little, only 10-50g/m2, its corrosion resistance is far worse than aluminized zinc pipe. To ensure quality, most manufacturers of regular galvanized pipes do not use electrogalvanizing (cold plating). Only small enterprises with obsolete equipment use electric galvanizing, and the price is cheaper. The Ministry of Construction has officially below, the elimination of cold galvanized pipe technology is backward, cold galvanized pipe shall not be used as water, air pipe. The galvanized layer of cold galvanized steel tube is electroplated, and the zinc layer is independently layered with the steel tube matrix. The zinc layer is thin, and the zinc layer is simply attached to the steel tube matrix and easy to fall off. So the corrosion resistance is poor. In new residential buildings, it is forbidden to use cold galvanized steel pipes as water supply pipes.
