Joining techniques

inline high-frequency welding

Alongside open profiles, Sadef has inline roll-forming capabilities for special formed tubes in various steel grades: pickled, pre-galvanised and stainless steel. Profiles can be high-frequency welded. Where necessary, on pre-galvanised profiles, the joint is brushed and subsequently provided with an anti-corrosion treatment. 

Where high-frequency welding is no longer possible, innovative laser welding can be applied.
Apart from joining by welding, formed tubes are made by flanging, clinching and gluing.
Special joining techniques are possible offline, such as TIG welding of stainless steel profiles and welding of accessories by certified welders.
