Leading Mild Steel Box Sections Forming Process And Advanced Technology

Yuantai Derun mainly has three major forming processes for producing mild steel box sections. Direct forming technology(DFT), first circular and then square forming process, and circular to square forming process. The direct forming production unit of Yuantai Derun Steel Pipe Manufacturing Group is a world leader. The precision and weld quality of the direct production unit in ordinary factories cannot meet the strict requirements of the buyer. However, Yuantai's direct squaring unit can achieve the precision of the formed R-angle, uniformity of wall thickness, smooth surface, flat inner and outer walls, and top quality weld seam in similar square steel pipe testing
