Square pipe is a common steel in the general steel market, with a high frequency of occurrence. The relatively high usage rate is galvanized square pipe (hot-dip galvanized square pipe), but now there is a term "galvanized square pipe". I think everyone must be wondering what is the difference between them?
First, the galvanized square tube is a hollow square cross-section steel with a square cross-section shape and size made of hot-rolled or cold-rolled galvanized strip steel or galvanized coil as a blank after cold bending processing and then high-frequency welding. Steel pipe; or galvanized from cold-formed hollow steel pipe prepared in advance and then hot-dip galvanized.
The galvanized strip square tube is formed by galvanized strip steel once, and the anti-corrosion time is not as long as that of hot galvanization, and the hot galvanized is processed by black square tube. Go to the galvanized square tube manufacturer to galvanize. After a high temperature of 1000 degrees, generally thin wall thickness is not used for hot-dip galvanizing.
There is also a difference in quality and classification. Galvanized square pipes can be processed into hot and cold galvanized square pipes, while galvanized strip square pipes cannot be made into hot galvanized square pipes. Because its wall thickness is relatively thin, The price of zinc square tube is much higher than the price of galvanized square tube.
Well, the above are some differences between the hot-dip galvanized square tube and galvanized strip square tube summarized by Yan Xinsenyu. I hope it will be helpful to everyone!
