U‑TUBES WITH
BOX-SHAPED DESIGN

The tubes with box-shaped design are bent twice at an angle of 90° and are sup­plied — accor­ding to the customer’s request — with dif­fe­rent inter­me­diate lengths made of seam­less or welded tubes. The manu­fac­tu­ring pro­ce­dures comply with the related stan­dard spe­ci­fi­ca­tions and ensure per­fect qua­lity. We are pleased to con­sider our final cus­to­mers’ spe­ci­fi­ca­tions as well as non-stan­dard designs made of steels, stain­less steels and spe­cial alloys.
