History & Heritage

Lindapter has a rich heritage in pioneering steelwork connections which began in 1934 when Bradford based engineer, Henry Lindsay first invented an entirely new concept of connecting steelwork with the Lindsay Bolt Adapter. It was a fast, cost-effective and adjustable way to clamp steel beams together without time-consuming drilling or welding.

Henry combined the words ‘Lindsay’ and ‘Adapter’ to create the now famous brand name. Since the 1930s Lindapter has evolved to become a world leading designer and manufacturer of steel-to-steel connections.
