Cold Rolled Square And Rectangular Tubes
Parameter of Carbon Square And Rectangular Tubes
Cold rolled square tubes and rectangular tubes are pipes with square or rectangular cross-sections made from hot-rolled steel strips or plates, which are deformed through multiple passes of cold rolling at room temperature. During the rolling process, it is possible to accurately control the dimensional parameters of the pipe, such as side length, wall thickness, and diagonal length, to achieve extremely high dimensional accuracy. Cold rolled square tubes and rectangular tubes come in a wide variety of specifications

Features of Carbon Square And Rectangular Tubes
- High strength and good load-bearing capacity. Carbon steel itself has relatively high strength. After being made intosquare or rectangular pipes, their structures can effectively distribute and transfer external forces, are not prone todeformation 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 suchas side lengths and wall thicknesses can be flexibly adjusted and customized according to different engineering designsand usage requirements.
- Good processing performance.
- Compared with some special alloy material pipes, the raw material cost of carbon steel square and rectangular pipes isrelatively low, and their production process is relatively mature with high production efficiency, effectively controlling theoverall cost.
- Carbon steel materials have good recyclability. After the pipes reach the end of their service life or are removed duringengineering renovations, carbon steel square and rectangular pipes can be easily recycled. After being remelted andprocessed, they can be made into new steel products again, which conforms to the concept of sustainable development
