Rollforming for welded profiles

STAM builds rollforming lines for welded profiles, giving high productivity and a short set up time, quickly modifying the rolls position.
These cross beams connect the vertical upright of shelving assemblies, creating a strong structure holding the shelves for supporting goods.
The cross beams can be made up either by using two roll formed profiles which are mechanically fixed and locked to one another; or using a single strip, roll formed to a closed section, with a folded seam or welded, where the two sides joint.
The ends of the cross beam can be attached to the uprights by means of a hook arrangement: the hook connections are fixed to the cross beam ends by welding or by bolts (thus the beam is punched during production).
