Fire protection for steel beams in Northumberland: 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.

Across Northumberland, fire protection for steel beams usually comes up when people want more light, a better layout or a way through to a new extension. That includes Blyth, Cramlington and Ashington, plus smaller towns and villages nearby. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.

What to expect

  • 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.
  • 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.
  • Building control treats fire protection as part of the structural approval, not an optional extra. If unprotected steel is found at inspection, the completion certificate is normally held back until the protection is in place and has been checked.
  • 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.

Four stages, one team

  1. Free visit

    A short visit to Northumberland to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building rules for Northumberland

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Fire protection for steel beams by town

Local questions answered

Which towns in Northumberland do you cover?

We cover towns including Blyth, Cramlington and Ashington, plus the villages and smaller towns around them.

Can you work on older or listed homes in Northumberland?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

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.

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.

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 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 much does fire protection for steel beams cost in Northumberland?

As a guide, budget £140–£560 per beam including VAT for fire protection to a steel beam in Northumberland, based on published UK cost guides adjusted for prices in the North East (-7%). 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.
