- Product Description
-
Q345B rectangular tube is also called Q345B rectangular tube, 16Mn rectangular tube, Q345 rectangular tube, square rectangular tube, rectangular tube, seamless rectangular tube, stainless steel rectangular tube, square rectangular tube, Q345B rectangular tube, large diameter thick wall rectangular tube, Q345C Rectangular pipe, stainless steel square rectangular steel pipe, seamless square rectangular steel pipe and other rectangular pipe products; Q345B rectangular pipe implements the national standard GBT 6728-2002. The size, shape, weight and allowable deviation of cold-formed hollow section steel for structure are produced, which is Q345B strip steel Rolled through process treatment. Q345B rectangular tube lies in its material Q345B material (low alloy) production and processing, which is very different from ordinary rectangular tube in raw material (Q195, Q215, Q235). Generally, Q345B strip steel (low alloy) is unpacked. , flattened, crimped, welded to form a round tube, and then rolled into a square tube from the round tube and then cut into the required length. The usual length is 6 meters, and 12 meters can be processed according to customer requirements. Generally, the small size is 50 pieces per package, and the large size is 4 pieces per package, and the weight is controlled at about 3 tons. Q345B rectangular tubes in stock are mostly in the large size of 80MM*80MM-500MM*500MM, and the thickness is 3MM-16MM.
