About our steel goalpost frames service in Risca
We carry out steel goalpost frames in Risca, covering the NP11 postcode district. The wider Caerphilly area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
When a rear wall is opened almost corner to corner, or the brickwork either side is too thin, cracked or broken up by openings to take a concentrated load, a beam on padstones is not enough. A goalpost frame brings its own supports: two columns carry the beam's ends straight down to new foundations, so the walls around the opening are not relied on.
What to expect
- Stability is part of the design, not just strength. A frame standing in a wide opening can sway sideways if the joints are too flexible, so the engineer decides whether the connections must be moment-resisting or whether the frame is tied back to the surrounding structure.
- A goalpost frame usually takes longer than a single beam because the pads need digging, inspecting, pouring and time to gain strength before the columns take load. The engineer sets when the frame can be loaded.
- Columns are commonly universal columns or square hollow sections, welded to steel base plates at the foot and cap plates at the head. Holding-down bolts fix the base plates to the pad, and grout fills the gap beneath once the frame is level.
- Each column usually needs its own concrete pad foundation, because a column delivers a heavy point load that an ordinary floor slab or old strip footing may not take. The engineer sets the pad size and depth from the load and the ground conditions found.
- Goalpost frames are made to measure, so accurate site dimensions matter. Floor-to-ceiling height, the finished floor level and the width between column positions are taken before fabrication, because a frame that is a few millimetres out cannot simply be trimmed on site.
Four stages, one team
Free visit
A short visit to Risca 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 the application or notice to Caerphilly County Borough Council under the Building Regulations as they apply in Wales, before work starts.
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 Risca
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Caerphilly County Borough Council handles building control for Risca. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.
Steel goalpost frames in Risca: your questions
Who approves steel goalpost frames in Risca?
Structural work in Risca needs a building control application to Caerphilly County Borough Council under the Welsh regulations, with a commencement notice before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Do you also work near Risca?
Yes. We also cover nearby towns including Cwmbran, Blackwood, Pontypool and Gelligaer.
Can a goalpost frame be hidden?
Usually, yes. The columns can be boxed in with fire-rated plasterboard so they read as small piers, set inside new walls, or hidden within the line of an extension's side walls. The beam is boxed like any other steel. Some owners prefer to leave the frame exposed and painted as a design feature.
How long does it take to install a steel goalpost?
Allow around one to two weeks on site for a typical job. Breaking out and digging the pads, the foundation inspection, pouring concrete and letting it gain strength take up much of that time. Erecting and bolting the frame itself is often done in a day, followed by inspection and boxing in.
What is the difference between a goalpost and a portal frame?
A domestic goalpost is a simple version of a portal frame. Both use columns and a beam joined together, but a full portal frame has rigid joints designed to resist sideways loads on its own, as used in steel-framed industrial buildings. In a house, the engineer decides how rigid the goalpost joints need to be for that opening.
