Adjustable girder clamp used to quickly connect steel beams with flat or tapered flanges. High slip resistance for tensile, frictional and combined load applications.
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
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.

Faster to Install
No drilling or welding!
Reasons to choose Lindapter
Save time and money
Clamping two steel sections together avoids time-consuming welding or conventional drilling and bolting.
On-site drilling and welding is avoided, removing the need for hot work permits and encouraging safer site conditions.
Lindapter clamps are manufactured from high strength materials to resist high load requirements and harsh environments.
Industry leading approvals
Lindapter has earned a reputation synonymous with safety and reliability, gaining multiple independent approvals.
Quickly align steel sections by sliding the section into the correct position before tightening the Girder Clamp to complete the installation.
Free connection design
Lindapter’s experienced Engineers can design a bespoke connection based on your specific requirements free of charge.
