- Lintel Length
Available to suit 90mm - 160mm cavity widths
This A/WIL Type Lintel is used to support an outer leaf of 100mm and an inner leaf of 215mm. Inner leaf constructed as shown. These lintels are commonly referred for standard loading conditions (see the loading tables for details).
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 2700mm.
Specify A/WIL for brickwork on outer leaf and A/WIL/K for blockwork outer leaf (built-in plaster key is standard finish for inner leaf).
All cavity lintels can be stepped if required (Standard step ~10mm).
