Estimating your lintels

For a 900 mm clear opening, add at least 150 mm of bearing at each end: the lintel needs to be at least 1,200 mm long. Then pick the type for the wall build-up and check the load in the manufacturer's table, or ask your engineer if the opening carries a floor or roof.

Getting lintels onto your County Londonderry site

Lintels are long, so tell us about tight access. Shorter lintels can travel with a mixed load; long steel lintels are handled by hand or crane. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• On busy streets in County Londonderry, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Choosing lintels

Steel or concrete?

Steel cavity lintels support both leaves and include insulation to limit cold bridging. Concrete lintels are simple and robust for single leaves and internal walls.

Do I need a cavity tray?

Over openings in cavity walls, water in the cavity has to be directed outwards. Many steel lintels need a separate cavity tray and stop ends; check the lintel maker's detail.

In Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.

Your questions answered

Do you deliver lintels to trades and homeowners in County Londonderry?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Can lintels be delivered with my blocks?

Yes. We combine them on one lorry where the lengths and the route allow.

Is there a minimum order for delivery to County Londonderry?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Can you tell me which lintel to use?

We can suggest options from the manufacturers' load tables based on the opening, wall type and load you describe, but for anything structural the final choice should come from your designer or engineer, and be approved through building control.
