Our ERW square/rectangular steel tubes are crafted from strip steel through advanced rolling and welding processes. Starting with the unwinding of strip steel, flattening, curling, and welding into round tubes, followed by rolling into square or rectangular shapes, is carefully controlled to ensure precise dimensions. These tubes are then cut to desired lengths to meet specific project requirements.
Our extensive range of square/rectangular steel tubes includes sizes from 10×10mm to 200×200mm for square tube, 20×40mm to 80×120mm for rectangular tube in outside diameter and 0.8mm to 17.5mm in wall thickness, offering a reliable source for ERW (electric resistance welded) structural steel tubing.
Square tube: 10×10mm to 200×200mm
Rectangular tube: 20×40mm to 80×120mm
Regular length: 5.8m or 6m or 12m
