Square tube is a common steel on the general steel market, a higher frequency.The use rate is relatively high galvanized square tube (hot dip galvanized square tube), but now there is a term "galvanized square tube", I think we must all want to know what is the difference between the two?
First, galvanized square tube is a kind of hot-rolled or cold-rolled galvanized steel strip or galvanized coil blank by cold bending molding and then by high-frequency welding made of a square cross-sectional shape and size of the hollow square cross-section steel pipe; or pre-made cold-formed hollow steel pipe and then by hot-dip galvanized galvanized galvanized.
The galvanized strip square tube is galvanized strip steel processing a molding, anti-corrosion time is not hot galvanized for a long time, hot dip galvanized black square tube processing out.In to galvanized square pipe manufacturers to go galvanized.After a high temperature of 1000 degrees, the General wall thickness is relatively thin not hot galvanized.
There is a difference in quality and classification, galvanized square tube can be processed into hot and cold galvanized square tube, and galvanized square tube can not be made of hot galvanized square tube, because of its relatively thin wall thickness, so galvanized square tube prices than galvanized square tube prices much higher.
Well, the above is the flame Xin Sen domain xiaobian summed up for you about hot galvanized square tube and galvanized square tube with some differences, I hope to help you!
