After years of process improvement, the outer arc of large-diameter ultra thick wall rectangular tube produced by the "round to square" process of Tianjin yuantaiderun group has successfully overcome the defects prone to cracks in the round to square bending process and the difficulties in controlling the flatness of the tube surface in the "deformation" process, which can meet the requirements of relevant standards at home and abroad for products and the control requirements of customers for special technical parameters, The products are widely praised in key engineering projects exported to the Middle East, and can basically replace the "box column" products in the original steel structure enterprises in China. The structural stability of rectangular tube products is much better than that of "box column" products welded by steel plates with four welds because they have only one weld, This can be seen in the requirements that Party A specifies the use of "rectangular tube" and prohibits the use of "box column" in some foreign key projects.

In terms of cold bending technology, Tianjin yuantaiderun group has nearly 20 years of accumulation and is able to customize special-shaped structural steel pipes according to customers' requirements. The picture shows the "octagonal steel pipe" customized by a large amusement park in China. Due to the design parameters, it needs cold bending and one-time forming. Due to the requirements of the diameter and wall thickness of the product, it has been inquired by major domestic manufacturers for nearly three months. Finally, only Tianjin yuantaiderun group has met its various requirements, successfully produced nearly 3000 tons and completed all the supply services of the project alone.

Facing the market and taking the route of "customization" is the firm marketing strategy of Tianjin yuantaiderun group. To this end, Tianjin yuantaiderun group, with the ultimate goal of "all rectangular tube products Yuantai must be able to produce" and market-oriented, insists on investing more than 50 million yuan every year in the research and development of new equipment, new molds and new processes. At present, it has introduced intelligent tempering equipment to produce outer arc rectangular tubes for glass curtain wall engineering, It can also be used for annealing stress relief or hot bending of rectangular tubes, which greatly enriches the processing capacity and product range, and can meet the customer's one-stop procurement needs of rectangular tubes.
