Both hot-dip galvanized square pipe and hot-dip galvanized square pipe can be welded by electric welding, but the welding of hot-dip galvanized square pipe can only use 2.5 electrode, the current is adjusted to 80A, it is better to weld with fluorine or oxygen if possible. And galvanization belt square pipe is to use galvanization strip steel processing a molding, anticorrosive time is not long time of hot galvanizing, hot galvanizing is black square pipe processing. Galvanize at the galvanizing square pipe manufacturer. After 1000 degrees of high temperature, the wall thickness is relatively thin do not do hot galvanizing.
Still have is the difference on quality and classification, galvanized square pipe can be processed into hot and cold galvanized square pipe, and galvanized with square pipe can not make it hot galvanized square pipe, because its wall thickness is thinner, so compare, hot galvanized square pipe than galvanized square pipe price is higher, galvanized layer is thicker, save time page is longer.
