What fire protection for steel beams involves in Llandeilo
Llandeilo has a mix of housing, and fire protection for steel beams needs a slightly different approach in each. We also cover the surrounding towns and villages in Carmarthenshire. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
A bare steel beam is strong at room temperature but loses much of its load-carrying capacity once it gets hot enough in a fire. If that beam holds up a floor or the walls above, it matters to everyone in the building. Fire protection slows the rate at which the steel heats up, buying time for people to get out safely.
Worth knowing before you start
- Fire boarding should not be cut into casually later on. Downlights, cables and pipes pushed through the boxing can weaken it, so services are planned before boarding, and any openings are sealed with suitable fire-stopping materials.
- Older homes sometimes have steel fitted decades ago with no protection at all, or boxed in ordinary timber and hardboard. When this turns up during other work, we can check what is there and price protection to suit today's requirements.
- Steel does not burn, but it loses stiffness and strength as it heats. Protection is there to keep the temperature of the beam down for a set period, so the floor or walls it carries stay up while people leave.
- Boxing a single beam usually takes around a day, plus skimming and drying. Intumescent coatings need each coat to dry before the next goes on, so they can take several days depending on the thickness required and the room temperature.
- Boarding is fairly clean work, but coatings need a clean, dry and well-ventilated room at a suitable temperature. Dust from other trades can spoil the surface, so painting is normally scheduled once the messy work in that room is finished.
How the job runs in Llandeilo
Survey in Llandeilo
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit the application or notice to Carmarthenshire County Council under the Building Regulations as they apply in Wales, before work starts.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building control and neighbours in Llandeilo
Welsh building regulations treat beams and new openings as controlled building work. We apply to Carmarthenshire County Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Questions about fire protection for steel beams in Llandeilo
Do you also work near Llandeilo?
Yes. We also cover nearby towns including Ammanford, Ystradgynlais, Carmarthen and Clydach.
How much does fire protection for steel beams cost in Llandeilo?
As a guide, budget £140–£550 per beam including VAT for fire protection to a steel beam in Llandeilo, based on published UK cost guides adjusted for prices in Wales (-9%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Is boxing in a steel beam cheaper than intumescent paint?
Usually, yes. Boxing with fire-rated plasterboard tends to cost less for steel that will be hidden. Intumescent coatings generally cost more because of the product and the number of coats needed, but they let the beam stay visible. Where either method would work, both can be priced on the itemised quote so you can compare.
How long does intumescent paint take to apply?
Several days in most cases. Each coat has to dry before the next is applied, and the number of coats depends on the thickness needed. Cold or damp rooms slow drying, so the space is kept warm and ventilated, and the top coat goes on once the full build has been measured.
How thick does intumescent paint need to be on a steel beam?
There is no single figure. The thickness depends on the steel section, how many sides are exposed and the fire period required, and the coating manufacturer's data sets the dry film thickness for each case. The applied thickness is measured with a gauge once the coats have dried and recorded for building control.
What happens at the survey visit in Llandeilo?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
