Steel Lintel FAQs

  • What if you don’t have the lintel code I need?

    We have a technical department that can assist – please call us and ask for lintel technical.

    Our manufacturers also have great technical departments that can assist as below;

    Catnic Technical – 02920 337900

    Stressline Technical – 01455 272457

  • How to install a steel lintel?

    Installation should always be inline with the manufacturers guidelines. If you are in doubt as to the structural performance or suitability of a lintel then please contact the manufacturers technical department before ordering/installation.

    Each lintel is different but most steel lintels should be propped at 1.2m ctrs and not removed until the mortar has cured.

    Minimum recommended end bearing = 150mm. The lintel should be bedded on mortar and levelled both along the lintel and across its width. Full bricks, blocks or padstones should be used as bearing areas. Do not bear onto cut blocks.

    All external wall lintels MUST be installed with a flexible damp proof course (DPC) or cavity tray. In the case of cavity walls the cavity tray should extend not less than 50mm beyond the cavity return.

    Inner and outer leaves supported by lintels should be raised together to avoid excessive eccentricity of loading.

    Masonry must not overhand any flange by more than 25mm.

    Masonry above the lintel should be allowed to cure before applying floor or roof loads.

    Further guidance can be found in the manufacturer’s literature.
