- Lintel Length (mm)
Available to suit 90mm - 210mm cavity widths
The HD Type Lintel shown above is for a brickwork outer leaf, where the window or door frame is not positioned within the cavity. The inner leaf is suited for a rendered finish as it provides a built-in plaster key.
The HD/K Type Lintel also shown is best suited for a rendered outer leaf, as it provides a plaster key for both the inner and outer leaf. These lintels are commonly referred for heavy-duty 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 3000mm and 250mm increments from 3000mm up to and including 4000mm.
All cavity lintels can be stepped if required (Standard step ~10mm).
