Lintel Description

This single leaf lintel is suited to heavy duty loading conditions to support the outer leaf of cavity wall construction.

Steel lintels should be installed with a minimum end bearing of 150mm, bedded on mortar and levelled along its length and across its width. The lintel should be suitably propped to facilitate speed of construction (see loading table for details). All lintels should be installed with a damp proof course (DPC). See installation instructions in downloads for further information.

Standard lengths are manufactured in 150mm increments up to 3000mm and 250mm increments from 3000mm up to and including 3500mm.

The L25/J can be supplied to suit plaster (specify L25J/K).
