Steel Connections

For over 80 years Lindapter has pioneered the design and manufacture of quality steel connection solutions, providing a unique and proven concept: innovative clamping systems that eliminate the need to drill or weld steel sections, reducing installation time and labor costs. Lindapter connections and Girder Clamps are ideally suited for both new construction and the refurbishment of existing structures.

Hollow Section (HSS) Connections

The range consists of the legendary Hollo-Bolt® and Lindibolt®, creating simple, cost-effective connections of HSS and other hollow sections, or conventional steel where access is available from one side only. The Hollo-Bolt® can be used as a primary structural connection as detailed in the SCI/ BCSA publication ‘Joints in Steel Construction - Simple Connections’.

Pipe / Conduit Supports

Lindapter provides solutions for supporting HVAC equipment, pipe work, fire protection/sprinkler systems, suspended ceilings and electrical equipment from structural or secondary beams.

Steel Floor Connections

Lindapter’s concept extends to their innovative connections that secure steel flooring to supporting steel without the need of on-site drilling or welding. Access to the underside of the flooring is not required, eliminating the need for costly scaffolding or elevated floors. Installation can be carried out quickly and safely from above, often by one person, significantly reducing costs.

Structural Engineering at its Best.
