Fire protection for steel beams in Dundee: how it works

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.

Fire protection for steel beams is one of the most common structural jobs in homes across Dundee. We cover the whole area, from the centre out to the suburbs. Every job starts with a survey visit, then calculations from a structural engineer, so the steel suits the house in front of us rather than a rule of thumb.

Key points for your project

  • 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.
  • 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.
  • The fire resistance needed depends on the building and where the steel sits. In a typical two-storey house, elements of structure commonly need 30 minutes, but taller homes, flats and commercial premises can need more. The engineer and building standards confirm the figure.
  • 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.
  • 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.

What happens, step by step

  1. Survey in Dundee

    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 warrant

    A building warrant is applied for from Dundee City Council, and work starts only once the warrant has been granted.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building standards inspects it, and we make good.

Guide prices for fire protection for steel beams in Dundee

As a guide, budget £140–£550 per beam including VAT for fire protection to a steel beam in Dundee, based on published UK cost guides adjusted for prices in Scotland (-9%).

JobTypical guide rangeWhat it usually covers
Fire protection to a steel beam£140–£550 per beamFire-rated board boxing or an intumescent coating system as specified
RSJ supply and fit (single beam)£730–£2,280 per beamBeam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately)
Building warrant fee£215–£435Statutory fee set by the estimated value of the work: £215 up to £5,000, rising on a sliding scale (fees from 1 April 2026)
Steel beam replacement£1,800–£5,000Propping, removing the failed beam, new steel on proper bearings, approval and making good

Approvals in Dundee

Scottish rules are stricter on timing than in England: the building warrant must be in place before the wall is touched. We prepare the application with the engineer's calculations and submit it to Dundee City Council. The finished work is then certified and a completion certificate submitted for acceptance.

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.

Fire protection for steel beams in Dundee: your questions

What happens at the survey visit in Dundee?

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 you cover Dundee for fire protection for steel beams?

Yes. We carry out fire protection for steel beams in Dundee. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

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 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.

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.

Will building standards check the fire protection on my beam?

Yes. Building standards 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.
