The Birtley CB90 Cavity Wall Lintel is a robust solution designed specifically for cavity walls with widths between 290mm and 310mm. This lintel offers reliable support for both residential and commercial construction projects. Manufactured from high-quality, hot-dip galvanised steel, it delivers superior corrosion resistance and durability, ensuring lasting performance even in challenging environments. This lintel is available in a variety of lengths from 750mm to 4800mm.
