This insulated steel box lintel is manufactured by Keystone for use in supporting masonry over openings such as doors and windows. With a length of 2400mm, height of 150mm, and width of 95mm, it is suitable for a range of cavity wall applications where a robust horizontal support is required.
The lintel features galvanised steel construction and integrated insulation, helping to minimise cold bridging in new builds or extensions. It is typically installed during the external wall construction phase by bricklayers or builders, ensuring structural continuity across the opening.
