A brand-new square tube mill by WRD is delivered. This tube mill adopts advanced direct forming technology, enabling efficient production of various square and rectangular pipe products. Compared with the traditional "first round then square" process, this direct forming production line has made significant technological breakthroughs: in terms of efficiency improvement, it eliminates the link of pressing round pipes into square ones, increasing the production speed by more than 30%; in terms of precision guarantee, the multi-pass progressive forming technology ensures the control of side length tolerance and right-angle precision; in terms of cost optimization, it reduces material deformation loss, improves steel strip utilization, and significantly reduces production costs; it also has flexible adaptability, and can switch between different specifications in a short time through a quick die change system.

As widely used profiles in modern industry, square and rectangular pipes play an important role in many fields due to their stable structure and convenient installation. In the field of building structures, they are often used in building frames, steel structure workshops, bridge supports, etc. Their regular geometric shape is easy to connect and fix, can bear large loads, and can maintain the overall beauty. For example, the curtain wall support systems of large commercial complexes mostly use high-precision rectangular pipes, which can ensure installation accuracy and visual effects.

In terms of mechanical manufacturing and equipment frames, in industrial applications such as automated equipment, conveyors, and storage shelves, square and rectangular pipes have become the first choice because of their high rigidity and easy processability. The racks and guardrails in the production line usually use square pipes of standard sizes to ensure the stable operation of the equipment. Modern furniture (such as display racks, tables and chairs) and interior decorations (such as stair handrails, partitions) also widely use square or rectangular pipes after surface treatment. Their flat edges and corners are easy for subsequent processing such as spraying and electroplating, and can also meet the needs of design aesthetics.

In addition, the new energy and transportation facilities fields also have demands for them. Emerging fields such as photovoltaic brackets and new energy vehicle battery frames have significant demands for the lightweight and high-strength characteristics of square pipes; rectangular pipes are often used in guardrails and support structures of rail transit, taking into account safety and economy.
