Planning fire protection for steel beams in Hertfordshire
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.
From the first survey visit to the completion certificate, we take care of fire protection for steel beams across Hertfordshire. Towns we cover include Stevenage, St Albans and Hoddesdon, among other places in the area. The engineer sizes the steel, we deal with building control, and our team fits and packs the beam before making good.
Worth knowing before you start
- 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.
- 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.
- 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 control may ask for it, and it helps answer queries when the house is sold.
- 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.
From survey to sign-off in Hertfordshire
Free visit
A short visit to Hertfordshire to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
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.
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.
How much should I budget in Hertfordshire?
As a guide, budget £160–£640 per beam including VAT for fire protection to a steel beam in Hertfordshire, based on published UK cost guides adjusted for prices in the East of England (+6%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Fire protection to a steel beam | £160–£640 per beam | Fire-rated board boxing or an intumescent coating system as specified |
| Steel column or post | £530–£1,590 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Steel beam replacement | £2,100–£5,850 | Propping, removing the failed beam, new steel on proper bearings, approval and making good |
| Structural calculations for a beam | £260–£800 | Site measure or photos, beam and padstone design and calculations for building control |
Figures include our approximate regional adjustment for prices in the East of England (+6%) and are rounded. How these figures are worked out.
Approvals in Hertfordshire
For Hertfordshire, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
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 in Hertfordshire: your questions
Do you cover Hertfordshire for fire protection for steel beams?
Yes. We carry out fire protection for steel beams in Hertfordshire. 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 Hertfordshire?
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.
My steel beam was fitted years ago without fire protection. What should I do?
Have it looked at and protected to current requirements. Unprotected steel can raise questions when you sell, and if the original work was never approved, a regularisation application to building control may be needed in England and Wales. We can survey the steel and price both the protection and the paperwork route.
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.
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 control.
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.
