About our steel columns & posts service in Armagh City, Banbridge and Craigavon
A steel column is an upright structural element that collects the load from a beam, floor or roof and carries it down to a foundation. In homes it is usually a square or circular hollow section or a universal column, welded to a base plate fixed to a concrete pad, and sized by a structural engineer for the load it carries.
Homes across Armagh City, Banbridge and Craigavon range from Victorian terraces to post-war semis and newer estates, and steel columns & posts look different in each. That includes Craigavon, Banbridge and Portadown, plus smaller towns and villages nearby. We plan the steel, the temporary support and the approvals around the building, then fix the price in writing once the scope is agreed.
Worth knowing before you start
- 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.
- While the existing support is removed or the new column goes in, props hold the beam and the structure above. They are only taken out once the column is fixed, packed tight at the head and grouted at the base.
- 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.
- Columns on upper floors cannot simply stand on joists. The load has to be traced down through the building to the ground, which can mean a column directly below, a beam to collect it, or a redesign of the layout.
- Adding a structural column is building work that building control needs to approve, with the pad usually inspected before concrete and the column before it is covered. The completion certificate at the end is the record to keep for any future sale.

As a guide, budget £430–£1,290 per column including VAT for steel column or post in Armagh City, Banbridge and Craigavon, based on published UK cost guides adjusted for prices in Northern Ireland (-14%).

Can you replace an old timber or cast iron post?
Usually, yes. Old posts in cellars, garages and converted shops are often undersized, rotten or of unknown strength. The engineer assesses the load they carry and specifies a new steel column and pad. The structure is propped while the old post comes out, and the new column is packed tight before the props are removed.
Can a steel column be left exposed?
Yes, many people leave a column on show, painted to suit the room. In homes exposed steel commonly needs fire protection, often intumescent paint applied to the specified thickness as part of a compatible paint system. Building control checks the protection meets what was specified. Boxing in with fire-rated plasterboard is the alternative where a hidden column is preferred.
Can I put a steel post in the middle of a beam?
Yes, a central post is a common way to support a long beam, and it often lets the engineer specify a shallower steel. The post needs its own foundation and has to sit somewhere that works with the room layout. The engineer compares a post against a single deeper beam and specifies whichever suits the loads and the space.
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 soon can steel columns & posts start in Armagh City, Banbridge and Craigavon?
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.
