black square steel hollow section-Yuantai Derun

1.What's black steel box section?

Black steel box section refers to the square steel hollow section that has just been removed from the production line, and its surface has not undergone any coating processing on the original steel surface, which is also commonly referred to as black square tube.

2.Black square steel hollow section forming process

Yuantai Derun mainly has three major forming processes for producing black steel box section. Direct forming technology, 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
