This insulated steel box lintel from Keystone Lintels Ltd provides robust support for masonry openings in cavity or solid wall applications. Manufactured from galvanised steel, it offers reliable durability and is suitable for use in general build projects where a standard-duty lintel is required.
With a length of 2550mm and a height of 150mm, this lintel is designed for walls between 100mm and 215mm in width. The integrated insulation helps maintain thermal performance across structural openings, making it a practical choice for supporting brickwork or blockwork above doors and windows on site.
