Introducing The Launch of The All In One Girder Clamp


Lindapter, the inventor of the original Girder Clamp and Hollo-Bolt has developed the Type AAF, a new High Slip Resistance (HSR) clamp for connecting steel sections, offering adjustability, anti-corrosion protection and high load capacities, even in low temperature environments.

Lindapter’s flagship product is the latest addition to its HSR family of clamps designed for high load requirements including frictional, tensile and combined load applications. The clamp features an innovative 2-part design that self-adjusts to suit a range of flange thicknesses, allowing contractors to use a single product type for multiple connection requirements. Typical applications include connecting steel framed roofs, pipe supports and mechanical handling equipment, while specialist applications include the renovation of bridges and offshore platforms.

Manufactured from SG iron with specific low temperature properties, the Type AAF provides resistance in cold environments where impact strength is important. Durability also extends to corrosion protection as the product is supplied with a hot dip galvanized coating as standard. Engineers can be confident that they are specifying a safe and reliable connection as load capacities have been verified by independent testing.

Compared to conventional methods such as drilling or welding, the Type AAF can be installed in minutes without the need for hot work permits, reducing construction time and labor costs. For additional convenience during installation, Direct Tension Indicators (DTIs) can be used to ensure the correct tension is applied to the fasteners (visit the Lindapter website for full details).

The Type AAF is available now from UCC Steelwork Connections in sizes 1/2”and 5/8”. Lindapter has published a new brochure ‘High Slip Resistance Clamps by Lindapter’ to support the product launch, to get your copy click the following link. Download the brochure
