Lintel Description

Available to suit 215mm wall

Standard Loading conditions to suit 215mm solid wall construction. To achieve loading figures lintel must be built in with stone, block/brick-work as shown.

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 stocked in our yard up to 2550mm.

As standard the L31 is designed for stone or brick finish and is manufactured with a soffit plate. This is a continuous piece of galvanised steel welded to the underside of the lintel showing no welds and can be painted to suit finish.

The L31 can also be supplied to suit plaster (specify L31/K).

(See Box lintel for stronger loading conditions and longer lengths).
