The difference between galvanized square and galvanized steel
The galvanized pipe with square tubes is galvanized steel strip processing, forming, anti-corrosion time, there is no hot galvanizing time, hot galvanized is processedThe black tube. Galvanized in galvanized square tube factory. After 1000 degrees of high temperature, the general wall thickness is relatively thin, can not do hot-dip galvanizing.
Hello, SECC is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; galvanized square cold-formed steel hollow or well in advance of the hot dip galvanized after processed tube.Galvanized square steel: first the steel bar is solid. Different from the square pipe, hollow, belong to the pipe. The steel surface is galvanized, galvanized steel.
There is a difference in the quality of classification and can be processed into cold and hot dip galvanized pipe, galvanized pipe, galvanized pipe and galvanized belt can not be made, because of its wall thickness is thin, so the price will take the price dip galvanized pipe is much higher than galvanized pipe.
The first dip galvanized pipe is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency. Or the cold formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
