About our fire protection for steel beams service in Bangor, Gwynedd

Our fire protection for steel beams service in Bangor, Gwynedd covers everything from the first visit to the completion paperwork. Our coverage runs across Gwynedd, so nearby villages are included too. Postcode districts we cover here include LL57.

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-rated plasterboard is denser than standard board and contains additives that slow the passage of heat. It usually has a pink or red face, and the number of layers and fixing pattern come from the system specification rather than being decided on site.
  • Keep a record of what was fitted: the board type and number of layers, or the coating product, thickness readings and number of coats. Building control may ask for it, and it helps answer queries when the house is sold.
  • 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.
  • A common fault is applying intumescent paint over the wrong primer, or over one of unknown type. The products must be compatible, so where steel was primed long ago the primer is identified or the surface is cleaned back before coating.
  • Boxing is generally the lower-cost route for steel that will be hidden. Intumescent coatings cost more because of the product and the number of coats, and the price rises with the fire period and the size of the section.

How the job runs in Bangor, Gwynedd

  1. Survey in Bangor, Gwynedd

    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.

  2. 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.

  3. Building control

    We submit the application or notice to Cyngor Gwynedd under the Building Regulations as they apply in Wales, before work starts.

  4. 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.

Approvals in Bangor, Gwynedd

Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Bangor, Gwynedd the application goes to Cyngor Gwynedd or a registered building control approver, with the engineer's calculations, and a completion certificate follows the final inspection.

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 Bangor, Gwynedd

What happens at the survey visit in Bangor, Gwynedd?

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.

Do I need a party wall agreement for fire protection for steel beams in Bangor, Gwynedd?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.

Will building control check the fire protection on my beam?

Yes. Building control looks at fire protection as part of the structural work, normally at or before the final inspection. For boxing they may want to see the board before it is skimmed, and for coatings they may ask for the product details and thickness readings. We keep these records ready for them.

Can I put downlights in a boxed-in steel beam?

Only with planning. Cutting holes in fire boarding can weaken its protection, so any lights in or near the boxing need to be designed in, using fire-rated fittings or suitable fire-stopping where the board is pierced. It is far easier to sort this out before the boxing goes up than to adapt it afterwards.

Can I box in a steel beam with normal plasterboard?

Not where fire protection is required. Standard plasterboard is not designed to protect steel for a set period in a fire. Fire-rated plasterboard is used instead, fixed in the number of layers and with the fixings the system specifies, so the boxing performs as intended and passes when building control checks it.
