Hollo-Bolt, the original expansion bolt for structural steel

The ongoing Hackney regeneration scheme is one of London’s largest programmes for building and refurbishing homes.

As part of the project, 72 enclosed balconies were installed onto the front of the Kings Crescent apartment blocks to increase the living space and modernise the appearance of the estate.

The contractor required a safe method for connecting the pre-drilled steel hollow sections together to create the structural framework for the balconies. The engineers evaluated several products for speed, strength and durability before deciding that the Hollo-Bolt by Lindapter was the best solution due to the range of independent product approvals, including the CE mark.

Hollo-Bolts were used to create the splice connections for the steel hollow sections running up the vertical face of the buildings. The contractors also used Hollo-Bolts to attach the framework to the vertical trusses which formed the load bearing base for the balconies.

The Hollo-Bolts allowed a quick installation of the balcony extensions without drilling or welding, helping the contractors to finish the project on time and on budget.
