Keystone Lintels

Keystone Lintels

Keystone Lintels Limited is a leading manufacturer of steel lintels, founded in 1989. The short history of Keystone has been one of relentless expansion and continuous innovation whilst redefining the meaning of service in the lintel industry.

Production facilities in Birmingham, Cwmbran and Cookstown provide an efficient, flexible and ergonomic working environment, which is part of the culture of quality and service at Keystone.

Keystone has a large professionally qualified team, operating from modern production facilities throughout the UK and Ireland. Keystone is proud to set the standard in lintel design, production and delivery service. With knowledge of our customers’ ever-changing needs, we continually invest in specialist plant and equipment.  

Keystone produces more than steel lintels.  Our specialist range is designed to meet the needs of even the most complex project.  Keystone offers a custom design service for a range of special lintels and masonry support systems.  The Keyslip Brick Details range which consists of Brick Feature Lintels and Lightweight Headers and Sills, enables intricate brickwork detail to be carried out in a factory controlled environment.  These one piece units are delivered to site with bricks already bonded for final pointing.

In 2013, Keystone set new standards for thermal efficiency in steel lintels.  The award winning Hi-therm Lintel has remained the only BBA approved, one-piece, thermally efficient lintel in the market.  Keystone’s R & D team has continued in its quest for perfection and this year will see the launch of the new redesigned Hi-therm+ Lintel, which offers the same low psi values but is even more similar to a standard steel lintel for simple installation.
