Roll-forming is the process of transforming steel strips into profiles. The steel strip is cold-formed step by step over a number of roll-forming stations by means of upper, bottom and side rolls. It is a continuous process, each roll is responsible for the subsequent step in the transformation of the steel strip to its final form. Sadef's roll-forming process integrates strip and post piercing, allows online high-frequency and laser welding, integrated mechanical connections and profiles cut to actual length.
Sadef profiles are manufactured from the appropriate material (pickled, pre-galvanised, pre-painted, stainless steel) and can be provided with integrated functions through the online piercing. The special formed profiles can finally also be provided with a suitable surface treatment (cataphoresis and powder painting).
