Square and Rectangular HSS Characteristics Square and rectangular hollow sections (HSS) possess numerous unique characteristics that set them apart in the realm of construction materials. Their cross-sectional shape, being square or rectangular, allows for a more even distribution of forces when under pressure, thereby enhancing the overall structural stability. Additionally, HSS boasts high strength and rigidity, capable of withstanding substantial loads and deformations, ensuring structural safety. Furthermore, HSS exhibits excellent weldability, corrosion resistance, and high-temperature performance, enabling it to maintain its properties in harsh environmental conditions. Square and Rectangular HSS Production Process The production process of square and rectangular HSS primarily includes hot rolling, cold rolling, and welding. Initially, steel plates are processed into strips of the required thickness through hot rolling or cold rolling. These strips are then cut to specific widths and subsequently rolled and welded. During the welding process, appropriate welding methods and process parameters must be employed to ensure the quality and strength of the welds. After cooling, straightening, and cutting, the finished square and rectangular HSS products are obtained.
