What steel goalpost frames involve in Ammanford
Our steel goalpost frames service in Ammanford covers everything from the first visit to the completion paperwork. The wider Carmarthenshire area is covered as well. Postcode districts we cover here include SA18.
We arrange the engineer's design, building control, the foundation pads, temporary propping and the fabricated frame, then box it in and make good. Everything is set out in one itemised written quote, and the price is fixed in writing once the layout and specification are agreed.
Worth knowing before you start
- 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.
- Column pads can clash with drains, gas pipes and underfloor heating runs below the floor. These are located before digging, and if a drain runs where a pad needs to go, the engineer may move the column or redesign the pad.
- Keep the engineer's calculations, the frame drawings and the building control completion certificate together. They show a future buyer's surveyor how the opening is supported and save questions about the columns when the house is sold.
- A goalpost frame differs from a simple beam because the beam does not rely on the walls at its ends. The two columns and the beam are connected so the whole frame carries the load down into foundations of its own.

Questions about steel goalpost frames in Ammanford
Can you work on older or listed homes in Ammanford?
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.
Do you cover Ammanford for steel goalpost frames?
Yes. We carry out steel goalpost frames in Ammanford and the SA18 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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.
What is a goalpost frame in an extension?
A goalpost frame is a steel beam sitting on two steel columns, bolted together so it stands as one unit. In an extension it is usually placed where the old rear wall was, holding up the house above while leaving a wide, clear opening. The columns rest on concrete pads, so the frame does not depend on the surrounding brickwork.
Is a goalpost frame more expensive than a beam?
Generally yes, because there is more steel, more fabrication and new foundations to dig and pour. Against that, a goalpost can avoid rebuilding weak piers or strengthening walls so they can take a beam. Our itemised written quote shows the frame, pads, propping and making good separately so you can see where the cost sits.
Can I stay at home while the work is done in Ammanford?
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.
