What fire protection for steel beams involves in Cheshunt
Need fire protection for steel beams in Cheshunt? Our coverage runs across Hertfordshire, so nearby villages are included too. We survey the property, arrange the engineer's design, deal with local building control, fit the steel and make good, all under one quote for EN7, EN8 and EN10 addresses.
A bare steel beam is strong at room temperature but loses much of its load-carrying capacity once it gets hot enough in a fire. If that beam holds up a floor or the walls above, it matters to everyone in the building. Fire protection slows the rate at which the steel heats up, buying time for people to get out safely.
Worth knowing before you start
- 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.
- 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.
- 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.
- Fire boarding should not be cut into casually later on. Downlights, cables and pipes pushed through the boxing can weaken it, so services are planned before boarding, and any openings are sealed with suitable fire-stopping materials.
- 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.
Four stages, one team
Survey in Cheshunt
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.
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.
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.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Cheshunt
For Cheshunt, 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.

Questions about fire protection for steel beams in Cheshunt
Can you work on older or listed homes in Cheshunt?
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.
Can I stay at home while the work is done in Cheshunt?
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.
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 control checks it.
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.
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.
Who approves fire protection for steel beams in Cheshunt?
Structural work in Cheshunt needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
