Steel profile ROLL-FORMED

DAVEX profiles are manufactured to a special profile by linear roll-joining of two or more material strips without any additives. A material strip is thereby placed in a groove and a second one is then mechnically toothed through stamping at the contact edge. The toothed edge is then placed in the groove of the first material strip and pressed tightly in by joining rollers running along the material strip. The belt material is thereby often thicker than the bar material. The strip material can be cut to the desired length from coils with thickness ranging from 3mm to 20mm. This DAVEX procedure allows for permanent mechanical joining of both steel strips. Small caracteristic grooves appear on the side of the inserted material due to the joining process. The DAVEX technique combines either already ground material strips or completely different materials. Compared to welded profiles, profiles created using the DAVEX procedure show special caracteristics and must therefore be tested with regards to their adequacy in load-bearing conditions. To this aim, the factory provides the load limit for each particular case of material combination, which may then be used by the structural engineer to evaluate adequacy.
