What fire protection for steel beams involves in Aberdeenshire
Fire protection for steel beams is the layer of fire-rated board or intumescent coating applied to structural steel so it keeps its strength long enough in a fire for people to get out. Steel softens as it heats, so building regulations set a period of fire resistance for beams and columns, and the protection is chosen and applied to meet that period.
Homes across Aberdeenshire range from Victorian terraces to post-war semis and newer estates, and fire protection for steel beams looks different in each. Coverage takes in Inverurie, Banchory and Fraserburgh and everywhere in between. We plan the steel, the temporary support and the approvals around the building, then fix the price in writing once the scope is agreed.
Worth knowing before you start
- Intumescent paint looks like an ordinary coating but swells into a thick insulating char when heated. How well it performs depends on the dry film thickness, which varies with the steel section and fire period, so it is applied to a written specification.
- 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 standards may ask for it, and it helps answer queries when the house is sold.
- 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.
- 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.
How the job runs in Aberdeenshire
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building warrant
A building warrant is applied for from Aberdeenshire Council, and work starts only once the warrant has been granted.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Aberdeenshire
In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For Aberdeenshire, warrants are handled by Aberdeenshire Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.
There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.

Local questions answered
Do you cover Aberdeenshire for fire protection for steel beams?
Yes. We carry out fire protection for steel beams in Aberdeenshire. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do I need a party wall agreement for fire protection for steel beams in Aberdeenshire?
There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.
What is intumescent paint for steel beams?
Intumescent paint is a fire-protective coating that swells when heated, forming a thick insulating layer that slows the steel heating up. It lets you leave a beam on show while still meeting fire requirements. It must be applied at a specified thickness over a compatible primer, so it goes on to a written specification rather than like ordinary paint.
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.
Does a steel column need fire protection as well as the beam?
Usually, if the column is part of the load path. A column carrying a beam is just as important in a fire, so it normally needs the same fire resistance. Columns are often boxed with board or coated with intumescent paint, and the engineer's design and building standards confirm what applies to yours.
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 standards checks it.
Who approves fire protection for steel beams in Aberdeenshire?
Structural work in Aberdeenshire needs a building warrant from Aberdeenshire Council, granted before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
