The solution for concrete fixings

We offer a complete range of anchor rails made of the stainless steels 1.4571 (A5), 1.4404 (A4) and more recently, from 1.4362 (lean duplex steel): An approved universal system (Z-21.4-1826) for cost and installation-optimised concrete fixings.

The permissible loads for central tensile and diagonal forces as well as shear and diagonal force range from 2.0 up to 25 kN and cover all essential requirements of architects and planners.

This results in our profiles MBA 28/15, 38/17, 50/31 (equates with profile 49/30 or 50/30) and 52/34.

We also deliver curved anchor rails of a minimum radius of 500 mm (28/15 and 38/17) or 700 mm 50/31 and 52/34) respectively as well as welded corner profiles and special welded and perforated anchor rail constructions, fast and reliably according to design.

We are at your disposal for additional information on European approvals.


  • MOSO® MBA rails are manufactured from, among others, lean duplex steel 1.4362 which was introduced by us and is technically superior to the A4/A5 steels. Better corrosion resistance, twice the yield strength Rp0.2, higher rigidity of about 18%, higher sustained temperature resistance, higher fatigue strength, and much more.
  • By welding the shear connectors it is possible, according to DIBT approval, to use the shear connector of a lower corrosion resistance class and therefore provide more cost-effective solutions. Due to the lack of shear connector coverage (as they are pressed into the punched-through rails), other anchor rails systems require the use of the same material as the C-rail.
  • Inexpensive stainless steel hammerhead and hookhead bolts are readily available from us. Please contact us with your specific needs!
