Features of Carbon Square And Rectangular Tubes
High strength and good load-bearing capacity. Carbon steel itself has relatively high strength. After being made into square or rectangular pipes, their structures can effectively distribute and transfer external forces, are not prone to deformation or damage, and provide reliable support for building and mechanical structures.
Diverse specifications and size adaptability. There are a rich variety of specifications to choose from. The dimensions such as side lengths and wall thicknesses can be flexibly adjusted and customized according to different engineering designs and usage requirements.
Good processing performance.
Compared with some special alloy material pipes, the raw material cost of carbon steel square and rectangular pipes is relatively low, and their production process is relatively mature with high production efficiency, effectively controlling the overall cost.
Carbon steel materials have good recyclability. After the pipes reach the end of their service life or are removed during engineering renovations, carbon steel square and rectangular pipes can be easily recycled. After being remelted and processed, they can be made into new steel products again, which conforms to the concept of sustainable development.
