Type AAF High Slip Resistance Girder Clamp
Adjustable girder clamp used to quickly connect steel beams with flat or tapered flanges. High slip resistance for tensile, frictional and combined load applications.
Overview
The Type AAF girder clamp is used to achieve a fast steelwork fixing connection where high load capacities are present in either tensile, frictional or combined load directions. It features an innovative two-part design that incorporates a rocking washer to allow the clamp to self-adjust to suit a range of flange thicknesses. Manufactured from low temperature SG iron with a hot dip galvanised finish to provide high performance and anti-corrosion protection in cold environments down to -60°C
Features & Benefits
- High slip resistance clamp evaluated for tensile, frictional and combined load applications.
- Self-adjusts to suit flange thicknesses 6mm to 40mm (size M20).
- Safe working loads apply in temperatures as low as -60°C.
- Suitable for parallel and tapered flanges up to and including 10°.
- The tail spans slotted clearance holes.
- Lindapter recommends the use of DTI Washers conforming to EN14399-9 with the Type AAF.
- Independently approved for dynamic load applications to EN 1993-1-9. Contact us for more details.

Packing Pieces
Packing pieces are available to increase the clamping range. Download datasheet above for further information.
Location & End Plates
These plates ensure the clamps and bolts are located in the correct position relative to the supporting steelwork. Location plates are simple fabricated items designed to sit between the two sections to be clamped together to ensure the bolts are fixed at the correct centres. End plates are simple fabricated items that are pre-welded to support frames, bracket or sections, allowing connection to the supporting structure with standard Lindapter clamps. Download datasheet above for further information.

1) Slip resistant values calculated against movement exceeding 0.1mm.
2) Shot blast and painted steelwork.
3) For thicker flanges, packing pieces AFP1 and AFP2 are available (for AAF12 and AAF16 only) or packing piece AAFP3 (for AAF20 only).
4) For ease of installation when using 10.9 bolts Lindapter recommends using fastener assemblies to EN 14399-1.
