What Are The Types Of Galvanized Layers For Galvanized Square Pipes And Their Bending Strength

Galvanized square pipeIn new residential buildings, it is forbidden to use cold galvanized steel pipes as water supply pipes. The galvanized steel pipe with a nominal diameter of not more than 50mm should be subjected to a cold bending test. The bending angle is 90° and the bending radius is 8 times the outer diameter.
The zinc layer is an electroplating layer, and the zinc layer is independently layered with the steel pipe matrix. The zinc layer is thin, and the zinc layer is simply attached to the steel pipe matrix, and the galvanized square pipe is easy to fall off. Therefore, its corrosion resistance is poor.
