    Keystone Lintels

    Keystone Lintels Limited is a leading manufacturer of steel lintels, founded in 1989. All Keystone lintels satisfy the Thermal Performance requirements of all UK building regulations, standards BS 5977 Part 2 1983 and BS EN 845-2:2003.

    Keystone Lintel Features

    Corrosion Resistance

    Keystone’s standard range of lintels are manufactured from high quality grade pre-galvanised mild steel with a zinc coating of 600g/m² (including both sides). The ‘hot dipped, pre-galvanising’ process is carried out at the mill to ensure a more consistent quality of zinc coating. This guarantees a more effective, anti-corrosive system. Furthermore, pre-galvanised lintels are much more environmentally friendly than post galvanised lintels, and have a lower carbon footprint.

    Fire Performance

    Keystone lintels have been subjected to a fire test (ref: WARRES No. 101263) in accordance with BS 476:Part20: 1987, at Exova Warringtonfire and achieved a one hour fire performance.

    Lintel Life Span

    The Keystone lintel range complies with the technical requirements of the BLP (Building Life Plans) regarding the durability data of mild steel, cold formed lintels. The service life of Keystone lintels, when installed with a flexible DPC, will be the same as that anticipated for the building.
