This Keystone extra heavy duty cavity lintel is manufactured from galvanised steel and has a 600mm length. It is designed to provide structural support above openings such as windows and doors in cavity wall construction, accommodating an inner leaf between 125mm and 150mm and a 102mm outer leaf.
On site, it is commonly used where greater load-bearing capacity is required, especially in specialist applications and areas with significant structural demands. The galvanised finish assists with durability, making it practical for various general building projects involving brick or block cavity walls.
