Duplex friction welded stud anchors are formed in exactly the same process as our A4 variants, but manufactured from a higher strength class duplex stainless steel, giving superior corrosion resistance suitable for CRC IV applications.

Hmin is calculated by: Socket length (L) + Concrete cover (Cnom) Cnom acc. to EN 1992-1 with Cnom ≥ 20 mm
Intermediate values can be obtained by linear interpolation. Compressive forces on the anchors are not permitted.
The above capacities assume no close edge distance, please refer to FixPro software for actual capacities given your installation parameters.
