Planning steel columns & posts in Strabane
Our steel columns & posts service in Strabane covers everything from the first visit to the completion paperwork. Our coverage runs across Derry City and Strabane, so nearby villages are included too. Postcode districts we cover here include BT82.
Sometimes the right support for a beam is not a wall at all. A long span can be broken in two with a slim post in the middle, a beam can land on a column where the masonry below is weak, or the corner of an L-shaped opening can be held up by a single post instead of a brick pier.
Worth knowing before you start
- A column delivers its load to the ground through a small area, so it normally stands on a concrete pad foundation rather than straight onto a floor slab. The pad spreads the load into firm ground at a depth set by the engineer.
- Exposed columns are commonly protected with intumescent paint applied to the thickness the specification calls for, which keeps a slim profile. Boxed columns are clad in fire-rated plasterboard and finished with corner beads, skim and a skirting to match the room.
- The noisiest part is cutting the floor and digging the pad, usually a day's work. The concrete then needs time to gain strength, so the column is often fitted on a later visit once it has cured enough to take load.
- Older properties sometimes have cast iron columns, timber posts or brick piers doing this job, especially in cellars and former shops. Their condition and capacity are often unknown, so the engineer assesses whether they can stay or need replacing with new steel.
- The base plate is welded to the foot of the column and fixed to the pad with holding-down bolts. A cap plate at the top bolts to the beam above, so the two act together and the beam cannot slide off its support.
Four stages, one team
Survey in Strabane
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 Derry City and Strabane District 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 Strabane
Building control in Strabane is run by Derry City and Strabane District Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
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.

Local questions answered
Can you work on older or listed homes in Strabane?
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 I need a party wall agreement for steel columns & posts in Strabane?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
Will a column interfere with underfloor heating?
It can, because the pad has to be dug through the floor where pipes may run. We trace heating loops, drains and cables before cutting and, where possible, move the column position slightly to miss them. If a loop has to be cut, it is repaired and pressure tested by a heating engineer before the floor is reinstated.
How thin can a steel support post be?
It depends entirely on the load, the height and how the post is restrained, so there is no standard size. Hollow sections often give the slimmest look for a given strength, and an engineer can sometimes reduce the section by adding restraint partway up. They specify the exact section after calculating the load.
How long does it take to fit a steel post?
The column itself can often be fixed in a day, but the whole job usually spans a few working days. The floor is cut and the pad dug, building control inspects it, the concrete is poured and left to cure, and then the column goes in and is packed tight to the beam.
