System Components

Ancon Shearfix comprises double-headed studs welded to flat rails. It is manufactured to suit the specific requirements of each application.

Studs are manufactured in four diameters (12, 16, 20 and 24mm) from Grade 500N reinforcing bar. The heads are hot forged to three times the diameter of the bar. Studs are manufactured in custom heights to suit the slab thickness. The minimum stud height depends on the stud diameter. The following table lists the minimum stud heights as well as the respective minimum slab thickness.

Stud Diameter Min Stud Height Min Slab Thickness
12mm 95mm 140mm
16mm 95mm 140mm
20mm 135mm 180mm
24mm 375mm 410mm

Note: minimum slab thickness on 20mm concrete cover.

Studs are welded to the rail at the centres determined by our software or a design calculation. Shearfix rails are manufactured from 20mm wide steel profiles. The rail performs no structural function but ensure stud alignment and position within the slab.
