And galvanized belt square pipe is processed with galvanized steel strip once formed, corrosion prevention time is not as long as the hot-dip galvanized, hot-dip galvanized is processed black square pipe. In to galvanized square pipe manufacturers to galvanized. After 1000 degrees high temperature, the general wall thickness is thin can not do hot-dip galvanized.

There is also a difference in quality and classification, galvanized square pipe can be processed into hot and cold galvanized square pipe, and galvanized square pipe with galvanized tape can not be made into hot-dip galvanized, because its wall thickness is thinner, so the price of galvanized square pipe is much higher than the price of galvanized square pipe with galvanized tape.
