Individual fixing point with approval
- Normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete, seismic performance category C1 and C2 for sizes M8-M16)
- Examples include metal structures, metal profiles, brackets, base plates, supports, cable conduits, pipes, railings, machinery etc.
Individual fixing point without approval
For use in concrete < C20/25 and pressure-resistant natural stone
Can be used in dry indoor areas, outdoors (including in industrial atmospheres and close to the sea) or in wet rooms, provided that no particularly aggressive conditions are present

1) The partial safety factors of the resistances regulated in the approval and a partial safety factor of the actions of γF = 1.4 have been taken into account. For information on combining tensile and shear loads and the influence of the edge distance and anchor groups, please refer to the European Technical Approval Guidelines (ETAG), Appendix C. 2) The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. |
