Galvanized square steel tube is based on black square steel tubes which is of equal length of steel tube is the strip steel rolled through the processing. Generally galvanized square tube is the strip after unpacking, smooth, curly, form circular tube welding then again by circular tube rolling into square tube and then cut into required length is generally 50 per package. Also known as square and rectangular cold bending hollow section.
The technological requirements of the galvanized square pipe is the allowable deviation in the wall thickness of the galvanized square moment. When the wall thickness is not more than 10 mm shall not exceed the nominal wall thickness of plus or minus 10%. When the wall thickness is more than 10 mm for the wall thickness of plus or minus 8% except corners and weld area wall thickness.
