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.

Can I return an Item or cancel my order?
You can request this via the My Account section. However, please note many items in our range are cut from longer length stock profiles. These items are non-returnable and the order cannot be cancelled once the cutting has taken place. These items are therefore bespoke items to your selected length. You will receive a notification about this post purchase. Please contact us immediately to put you order on hold or cancel should you possibly wish to return an item post purchase. Our team can assist in notifying you if the items on your order are cut or non cut items. We can also inform you of this prior to you making an order should you require.
