Product Introduction

Square tube is a hollow steel tube with square or rectangular cross-section, which is processed by cold rolling, hot rolling or welding, combining high strength and light weight. The manufacturing process for welded square tubes is based on straight-seam welding, which is a low-cost and mature process, while the cold rolling or cold-drawing process achieves higher precision and a smooth surface. With a hollow structure that optimizes bending and compression resistance, as well as material savings, weight reduction, and ease of cutting, welding, and drilling, square tubes are widely used in scenarios such as building structures, machinery manufacturing, transportation, home decoration, and the energy sector.

Compared with round tube, square tube is easier to connect the plane, saving space; compared with H-beam and other solid profiles, its lightweight advantage is significant, but need to select according to the actual force demand. When choosing, you need to pay attention to the material rust resistance and wall thickness strength, and in the installation, you need to avoid welding deformation and strengthen the stability of the connection, as well as regular maintenance of the coating to extend the service life.

As one of the core materials of modern industry and construction, square tube has become the ideal choice for basic components in many fields with high cost performance and flexible adaptability.
