Sometimes a standard lintel just doesn’t suit the architectural detailing of a building’s design so a range of bespoke options are available on request.
The front flange of a lintel can be reduced in length. This is most useful when using a chamfered window head or narrow brick, when a standard flange would protrude.
To specify, add ‘RFF’ to the end of the lintel reference, followed by the projection of the flange e.g. CB50 RFF50.
To minimise the mortar bed thickness at the end bearings, e.g. when using stone heads and surrounds, the weather drip on the front flange of the lintel can be omitted.
To specify, add ‘ND’ to the end of the lintel reference e.g. CB50 ND.
A mesh can be welded to the underside of the front flange as a key to allow a rendered soffit. As the lintel is galvanized after the mesh is attached, it doesn’t compromise the integrity of the lintel. To specify, add ‘MF’ to the end of the lintel reference e.g. CB50 MF.
Where the inner leaf of a cavity wall is fair-faced and the inner flange of the lintel is not plastered, the plaster key on this flange can be omitted. To specify, add ‘NM’ to the end of the lintel reference e.g. CB50 NM.
Where the underside of the lintel is completely exposed, e.g. porches, driveways, etc., a closer plate can be welded prior to galvanizing to provide a neat, aesthetically pleasing finish to the soffit of the lintel. To specify, add ‘CP’ to the end of the lintel reference e.g. CB50 CP. ST Inner and outer leaf flanges can be staggered to allow for uneven coursing.
