This is a steel box lintel, supplied with integrated insulation, designed for use in cavity wall construction where support is required over structural openings. Manufactured from galvanised steel, it offers a robust solution for supporting masonry above doorways, windows and other apertures.
It is suitable for wall widths from 100mm to 215mm and has a length of 3750mm, making it practical for large-span openings. Typical on-site use includes installation by bricklayers or builders seeking a consistent method for supporting loads while also reducing thermal bridging in the wall detail.
