Datasheets(X)
CAD data (available after login)
- Individual or multiple attachment approved in normal weight concrete C20/25 to C50/60 (uncracked concrete only)
- For use in concrete < C20/25 and pressure-resistant natural stone without approval
- Suitable for anchoring medium to heavy loads in concrete: Mounting of e.g. metal structures, metal profiles, brackets, base plates, cable conduits, pipes, wooden structures, beams, purlins, fences etc.
- The W-FA/S galvanised steel is suitable for use in dry indoor areas

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