Application

This lintel is ideal for use in cavity wall construction where heavy loads must be safely transferred across openings. It is commonly specified on commercial and residential builds requiring robust lintel solutions for masonry or blockwork cavity walls. To ensure optimal performance, blockwork should be built tightly against the lintel’s inner face, and a mortar bed applied on top of the blockwork before laying floor units to achieve even load distribution. Propping the lintel during installation is recommended to speed up construction and maintain safety.
