Steel & Concrete Lintels for sites in Dyfed
A lintel is a beam that carries the masonry over a door or window opening; most UK houses use galvanised steel cavity lintels or prestressed concrete lintels.
We price lintels for jobs anywhere in Dyfed; send a list or the sizes of the job and we will quote it delivered.

A quick quantity check
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 Dyfed 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. Our standard mainland delivery area covers Dyfed.
- Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
- If the site is up a shared drive or behind other houses, tell us the distance from the road.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
Getting the right 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.
Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.
Steel & Concrete Lintels questions
Is there a minimum order for delivery to Dyfed?
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.
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 I add other materials to my Dyfed delivery?
Yes. Put everything on one list, from lintels to fixings and PPE, and we will price it as one delivery where the products can travel together.
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.
