Technical Innovation in Steelwork Connections

Established in 1934, Lindapter is the world’s innovator of steelwork clamping systems, eliminating the requirement to drill or weld steel. In comparison to traditional connection methods, Lindapter solutions allow rapid installation, significantly reduced costs while preserving the integrity of the steelwork.

Girder Clamps

The term Girder Clamp covers more than one design of connection. It is a description that is used for any type of configuration of Lindapter steelwork fixing connections that fasten steel sections together without the need for onsite drilling or welding.


This flexibility means the Girder Clamp is not an ‘off the shelf’ item, but a bespoke steelwork connection solution, individually designed and manufactured to suit your specific requirements.


The Original Expansion Bolt for Structural Steel. Suitable for hollow sections, tubes and where access is available from one side only. The Hollo-Bolt has full Seismic approval for resisting wind loads and seismic loads. For corrosion protection, the Hollo-Bolt® comes with additional JS500 protection as standard or hot dip galvanised.


Sizes M16 and M20 have a patented High Clamping Force (HCF) mechanism for optimised clamping force. Speedy installation with standard tools. This CE approved blind fixing was awarded the Design Council’s Millennium Product status for innovation in the year 2000.

Floor Fixings

Lindapter floor fixing range offers a fast easy to install solution. None of the products require any site drilling and/or welding and can easily be installed from above the flooring; this means no requirement access platforms giving easier compliance with the working at height regulations.


Both the Floorfast® & Grate-Fast® are covered by Lloyds Register Type Approval in respect of their clamping force and resistance to loosening in areas subject to shock and vibration. Without a need for the issuing of hot work permits.
