First of all, square and rectangular tubes have high strength. Due to their rectangular cross-sectional shape, square and rectangular tubes can withstand greater pressure and tension and are therefore widely used in structural engineering and construction. Not only that, square rectangular tubes also have good bending resistance and can withstand large deformations without being easily deformed or broken, ensuring the stability and safety of buildings and engineering structures.
Secondly, square and rectangular pipes have better corrosion resistance. After the surface of the square and rectangular pipe has been treated with anti-corrosion treatment such as galvanizing, it can effectively prevent corrosion of the steel by water, chemicals and oxygen, and extend the service life of the square and rectangular pipe. For this reason, square and rectangular pipes are widely used in fields with high corrosion resistance requirements such as marine engineering, power engineering, and chemical engineering.
Third, square and rectangular tubes have better processability. The cross-section shape of the square and rectangular tube is regular and the length can be customized, which is convenient for cutting, drilling, welding, cold bending and other processing processes, and can meet various complex structures and special needs. The processing performance of square and rectangular tubes has been fully applied in the manufacturing of vehicles, mechanical equipment, shelves, etc.
Fourth, square and rectangular tubes have better economy. Since the raw material prices of square and rectangular tubes are relatively low and the manufacturing process is simple and fast, the cost of square and rectangular tubes is relatively low and can meet the needs of mass production. In construction projects, the use of square and rectangular tubes can not only reduce material costs, but also save project time and improve project efficiency.
Square and rectangular tubes have become an indispensable and important material in industrial manufacturing and construction projects due to their high strength, corrosion resistance, processability and economy. In different fields and applications, square and rectangular tubes can exert their unique characteristics and advantages, making important contributions to the development of all walks of life.
