Rectangular tube (www.baowi-steel.com) is a hollow square cross-section lightweight thin-walled steel tube, also known as steel cold-formed profile. It is a square section steel with a square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, cold bending and then high-frequency welding. In addition to the thickening of the wall thickness, the corner size and edge straightness of hot-rolled extra thick-walled square tubes reach or even exceed the level of resistance welded cold-formed square tubes. 1. Material properties New rectangular tubes are often made of high-strength steel, aluminum alloy or composite materials, which have excellent strength and stiffness and can withstand large loads and deformations. Compared with traditional materials, the new rectangular tube is lightweight, corrosion-resistant, and wear-resistant, and can meet the high requirements for material performance in construction projects. 2. Design flexibility The new rectangular tube can be flexibly designed according to engineering needs and can be made into rectangular sections of various sizes and shapes to meet the needs of different structures. For example, in bridge engineering, new rectangular tubes can be designed into porous structures to improve the wind resistance of the structure; in building exterior wall decoration, they can be made into colored rectangular tubes to increase the aesthetics of the building. 3. Convenience of construction The ease of construction of the new rectangular tube is also one of its advantages. Because the material is light and easy to process, it can be prefabricated in the factory, reducing on-site processing and installation time and reducing construction costs. At the same time, the new rectangular tube has flexible connection methods, such as welding and bolting, to adapt to different engineering needs. 4. Environmental sustainability As society's awareness of environmental protection increases, new rectangular tubes also have obvious advantages in environmental sustainability. On the one hand, the new rectangular tube can use recyclable materials to reduce resource waste; on the other hand, the new rectangular tube has good corrosion resistance and durability, reducing the frequency of maintenance and replacement, and extending the service life of the building. In line with the concept of sustainable development. In summary, the new rectangular tube has shown many advantages in construction projects, including excellent material properties, strong design flexibility, high construction convenience, and good environmental sustainability. With the continuous advancement of science and technology and the continuous innovation of rectangular tube technology, it is believed that new rectangular tubes will play an increasingly important role in the field of construction engineering and inject new vitality into the development of the construction industry.
