What steel columns & posts involve in Hull
Steel columns & posts in Hull are planned around the house, not a standard kit. The wider the East Riding of Yorkshire area is covered as well. We visit, measure and check what the wall carries, then arrange calculations and building control approval before any steel is ordered.
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.
What to expect
- Hollow sections, either square or circular, give a neat, slim profile and are common where a post stays on show. Universal columns have an H-shaped section and are often used where the post will be boxed in or built into a wall.
- 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.
- 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.
- A tall, slender column can buckle under load before the steel itself is overstressed. That is why the engineer checks the height between restraints as well as the weight carried, and why a taller column may need a heavier section.
- 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.
What happens, step by step
Free visit
A short visit to Hull 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 a building notice or full plans application to Hull City Council, so approval is in place before the wall is touched.
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.

Approvals in Hull
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Hull City Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Questions about steel columns & posts in Hull
Do I need a party wall agreement for steel columns & posts in Hull?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
What happens at the survey visit in Hull?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
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.
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.
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.
