What fire protection for steel beams involves in South Lanarkshire

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.

Across South Lanarkshire, fire protection for steel beams usually comes up when people want more light, a better layout or a way through to a new extension. Towns we cover include Cambuslang, Dalserf and East Kilbride, among other places in the area. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.

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.
  • Exposed steel is popular in open-plan kitchens and loft spaces. An intumescent system can take a decorative top coat in most colours, although up close the finish has a slightly textured look compared with steel painted in a factory.
  • 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.
  • 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.
  • 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.

Four stages, one team

  1. Survey in South Lanarkshire

    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 South Lanarkshire 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.

How much should I budget in South Lanarkshire?

As a guide, budget £140–£550 per beam including VAT for fire protection to a steel beam in South Lanarkshire, 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
Steel column or post£460–£1,360 per columnColumn supplied and fitted with base and cap plates on a pad foundation

Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.

Approvals in South Lanarkshire

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 South Lanarkshire Council. The finished work is then certified and a completion certificate submitted for acceptance.

Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Questions about fire protection for steel beams in South Lanarkshire

Can I stay at home while the work is done in South Lanarkshire?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

Do you cover South Lanarkshire for fire protection for steel beams?

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

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.

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.

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.

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 standards.

What happens at the survey visit in South Lanarkshire?

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.
