What RSJ installation involves in Sandhurst
If you live in Sandhurst, RSJ installation can usually be planned and priced after a single survey visit. It sits about 10.0 miles from Woking, which we also cover. We cover GU47, and we fix the price in writing once the layout and scope are agreed.
People still call almost any steel beam in a house an RSJ, even though the sections fitted today are usually universal beams with parallel flanges. Whatever the name, the job is the same: a length of structural steel, made to an engineer's specification, carrying floors, walls or roof over a space where support used to be.
Things to plan for
- Padstones spread the concentrated load from each beam end into the masonry below. They may be concrete, engineering brick or a steel plate, depending on the engineer's design and the strength of the wall beneath.
- Steel for internal use is normally delivered with a primer coat to protect it during installation. Beams in damp positions, within external walls or exposed outside need a more robust coating or galvanising, as the engineer specifies.
- Where a long beam cannot be carried into a property in one piece, the engineer can design a bolted splice so it arrives in two or more lengths. The splice position and bolts are part of the calculations and must be installed exactly as drawn.
- Packing is what makes the beam work. Steel shims and dry-pack mortar fill the gap between the top flange and the structure above, so the load transfers onto the steel without the floor or wall settling down onto it.
- The engineer chooses the section type for the job. Universal beams suit most spans, universal columns are stockier and used as posts or where depth is limited, parallel flange channels fit against walls or timbers, and box sections suit slim or exposed members.
Four stages, one team
Free visit
A short visit to Sandhurst 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 Bracknell Forest Council, 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.

Approvals in Sandhurst
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 Bracknell Forest Council 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.

Local questions answered
Do you also work near Sandhurst?
Yes. We also cover nearby towns including Crowthorne, Yateley, Camberley and Farnborough.
Can you work on older or listed homes in Sandhurst?
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.
Is an RSJ the same as a steel beam?
In everyday use, yes. Builders and homeowners call most steel beams RSJs, whether they are universal beams, channels or columns. Technically an RSJ is one particular older section shape, but the engineer's drawing names the exact section type, so there is no confusion on site.
How is an RSJ installed?
The structure above is propped, the wall or opening is prepared, and padstones are bedded at each end. The beam is lifted onto them, bolted where needed and packed with shims and dry-pack. Props come out once it is carrying, building control inspects it, and the steel is then fire protected and finished.
Who decides what size RSJ I need?
A structural engineer. The size depends on the span, the loads from floors, walls and roof above, how stiff the beam needs to be and how its ends are supported. We arrange calculations from a qualified engineer, or fit to calculations you already have, rather than guessing a size.
How much does RSJ installation cost in Sandhurst?
As a guide, budget £900–£2,800 per beam including VAT for rSJ supply and fit (single beam) in Sandhurst, based on published UK cost guides adjusted for prices in the South East (+12%). 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.
