Planning RSJ installation in Newtownards
We cover RSJ installation in Newtownards (BT23) and the streets around it. Our coverage runs across Ards and North Down, so nearby villages are included too. Each job is designed by a structural engineer and approved through Ards and North Down Borough Council before work begins.
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.
Key points for your project
- An RSJ inside a home commonly needs 30-minute fire resistance where it supports elements of structure. Fire-rated plasterboard boxing is the usual method, with intumescent paint used when the beam is to remain visible.
- RSJ originally meant a rolled steel joist with tapered flanges. Most beams supplied for homes today are universal beams with parallel flanges, but the term RSJ has stuck, and builders, engineers and building control all understand what it means.
- 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.
- Delivery can make or break an RSJ job. A long beam has to turn through a front door, along a hallway and past the stairs, so routes are measured at the survey and alternatives such as a window opening are planned early.
- If you already hold calculations from an architect or engineer, we install to those. Where something on site differs from the drawing, such as a weaker wall or a different joist direction, the engineer is asked to confirm before work carries on.
What happens, step by step
Free visit
A short visit to Newtownards 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
A full plans application or building notice goes to Ards and North Down Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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.

| Structural calculations for a beam | £220–£640 | Site measure or photos, beam and padstone design and calculations for building control |
| Temporary works and propping | £130–£430 | Props, spreaders, needles and sole plates for a typical opening, installed and struck |
| Steel beam replacement | £1,700–£4,750 | Propping, removing the failed beam, new steel on proper bearings, approval and making good |

Building control and neighbours in Newtownards
Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Ards and North Down Borough Council covers Newtownards. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Local questions answered
Can I stay at home while the work is done in Newtownards?
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 you work on older or listed homes in Newtownards?
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 you fit an RSJ to my own engineer's calculations?
Yes. We install to calculations and drawings from your engineer or architect, as long as they cover the beam, bearings and any columns or connections. If site conditions differ from what the design assumed, we check with the engineer before carrying on.
Can an RSJ be delivered in sections?
Yes, where access is tight. The engineer can design bolted splice joints so a long beam arrives in two or more pieces and is joined in place. The splice has to be part of the calculations from the start, because it changes how the beam carries load at that point.
What is included in an RSJ supply and fit price?
Our itemised written quote sets out the calculations, building control, steel and fabrication, delivery, lifting, padstones, propping, labour, fire protection and making good as separate lines. Once the specification and scope are agreed, the price is fixed in writing, so you know the full cost before work starts.
