Product Description

Product Description:

Square pipe is a name for square pipe and rectangular pipe, that is, steel pipe with equal and unequal side length.  It is made of strip steel after processing and rolling.  Generally, the strip is unpacked, leveled, crimped and welded into a round tube, which is rolled into a square tube and then cut into the required length.  
 

Square tubes are classified according to their uses: square tubes for decoration, square tubes for machine tools, square tubes for mechanical industry, square tubes for chemical industry, square tubes for steel structures, square tubes for shipbuilding, square tubes for automobiles, square tubes for steel beams and columns, square tubes for special purposes.
