About our steel goalpost frames service in Mid and East Antrim
A steel goalpost frame is a beam supported on two steel columns, bolted together into one rigid unit shaped like a goalpost. It is used where the masonry either side of an opening cannot take the beam's load, or where a wide opening leaves little wall to bear on. The columns stand on base plates fixed to concrete pad foundations sized by the engineer.
Steel goalpost frames in Mid and East Antrim follows the same careful process wherever the property is: a survey, an engineer's design, the right approval and safe temporary works. We can survey in places such as Ballymena, Larne and Carrickfergus and the villages around them. We price it all up front so there are no surprises once the wall is open.
Things to plan for
- 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.
- While the old wall or piers come out, the floor, walls and roof above are held on props and needles. These stay in until the frame is fully bolted, levelled and packed, so the structure is never left without support.
- 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.
- 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.
- Price depends on the opening width, the loads the beam carries, the number of bolted connections, the depth of the pads and how easily the steel can be carried in. Any redesign after the ground is opened is priced before it goes ahead.
What happens, step by step
Survey in Mid and East Antrim
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
A full plans application or building notice goes to Mid and East Antrim Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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.

Building control and neighbours in Mid and East Antrim
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Mid and East Antrim that is Mid and East Antrim Borough Council. We submit a full plans application or building notice before work starts and book the inspections.
Northern Ireland has no Party Wall Act, so there is no statutory notice to serve. Where the steel bears into a shared wall, the title deeds and the general law apply, and agreeing the work with your neighbour in writing first is good practice.

Questions about steel goalpost frames in Mid and East Antrim
Do you cover Mid and East Antrim for steel goalpost frames?
Yes. We carry out steel goalpost frames in Mid and East Antrim. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
How soon can steel goalpost frames start in Mid and East Antrim?
Start dates depend on the engineer's calculations, the building control approval and any agreement needed with neighbours. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
Does a goalpost frame need foundations?
Yes, in most cases each column needs a concrete pad foundation beneath it. A column concentrates a lot of weight on a small area, and a normal floor slab is rarely designed for that. The engineer sizes each pad, and building control usually inspects the excavation before the concrete goes in.
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.
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.
Are goalpost frames welded or bolted?
Most domestic goalposts are bolted, with plates welded to the beam and columns in the fabrication shop and bolted together on site. That lets each piece be carried into the house separately. The engineer specifies the connection details, including whether the joints need to resist sway, and the fabricator makes the frame to suit.
Who approves steel goalpost frames in Mid and East Antrim?
Structural work in Mid and East Antrim needs a full plans application or building notice to Mid and East Antrim Borough Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
