The Keystone Internal Angle Steel Lintel INT/K-100 is an essential component for supporting openings in 100mm wide solid walls, crafted from high-quality pre-galvanised steel in an attractive zinc grey finish.

Designed for standard load applications, this lintel ensures structural integrity by allowing the mortar to cure for 24 hours before additional loads are applied, although it is not suitable for floor loads. It meets the thermal performance requirements set forth by building regulations across the UK, including England and Wales' Part L, Northern Ireland's Part F, and Scotland's Technical Handbook, section 6. Additionally, its robust fire performance has been verified through rigorous testing, achieving a one-hour fire rating.
