Product Description

A36 Grade 40, Grade 42, Carbon Steel Square/Rectangle Pipe Sch 40 Steel Pipe Square Tubing Price
Square tubes are classified according to their cross-sectional shapes: simple cross-section square tubes: square tubes and rectangular tubes. After the process is processed, it is rolled into strip steel. Generally, the strip steel is unpacked, flattened, crimped, and welded into a round tube, then the round tube is rolled into a square tube, and then cut to the required length. According to the production process, the square tube is divided into: hot-rolled seamless square tube, cold-drawn seamless square tube, extruded seamless square tube, and welded square tube. Rectangular pipes are divided into ultra-thick-walled rectangular pipes, thick-walled rectangular pipes and thin-walled rectangular pipes according to their wall thickness.
