Working out quantities for your South Glamorgan job
For a 1,800 mm clear opening, add at least 150 mm of bearing at each end: the lintel needs to be at least 2,100 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 South Glamorgan 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 South Glamorgan.
- On busy streets in South Glamorgan, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
Steel & Concrete Lintels: choosing well
Which lintel for my opening?
Measure the clear opening, add the end bearing each side, and note the wall type (cavity width, inner and outer leaf) and what sits above. Manufacturers publish load tables; for anything carrying a floor, roof or point load get an engineer or building control to confirm.
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.
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 in South Glamorgan: questions
Can lintels be delivered with my blocks?
Yes. We combine them on one lorry where the lengths and the route allow.
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 deliver lintels to a site with restricted access in South Glamorgan?
Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.
Is there a minimum order for delivery to South Glamorgan?
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.
