Galvanizing after processing：

According to the demand, hot-dip plating and electroplating are used for the construction and support pipe fittings. Generally, galvanized pipe fittings are processed first and then galvanized, which has a low cost. The disadvantages are that the inner surface is not easy to be plated, the black and red rust spots are serious, and the coating thickness is not easy to control. In the plating process, the threads are seriously damaged due to collision, which directly affects the accuracy of the threads and makes them difficult to install.

In order to avoid the above defects, the cost of the pipe fittings is increased, and all the pipe fittings are galvanized before processing to ensure thread accuracy.
