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 England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Delivering lintels in Greenwich

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. Greenwich is inside our standard mainland delivery area.

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Estimating your lintels

For a 2,700 mm clear opening, add at least 150 mm of bearing at each end: the lintel needs to be at least 3,000 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.

Steel & Concrete Lintels in Greenwich: questions

Do I need building control approval for a new lintel?

Making or widening an opening in a loadbearing wall is structural work, so in most cases yes. Building control or an engineer will confirm the lintel.

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.

Is there a minimum order for delivery to Greenwich?

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.

How soon can lintels be delivered in Greenwich?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
