What steel columns & posts involve in Bournemouth

For homes in Bournemouth and the BH1, BH2, BH3, BH4 and BH5 districts, we handle steel columns & posts from survey to sign-off. Our coverage runs across Dorset, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.

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.

Key points for your project

  • A post is needed when a beam has nothing adequate to bear on, or when a span is long enough that a central support gives a shallower, lighter beam. The engineer weighs up a column against a deeper beam for each layout.
  • Steel at floor level can corrode if it sits in damp. The detail at the base is designed to keep damp away, using grout, protective paint and the floor's damp-proof membrane, and a column in a cellar or garage may need a heavier coating.
  • 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.
  • 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.
  • 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.

Four stages, one team

  1. Free visit

    A short visit to Bournemouth to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. 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 Bournemouth

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 the local council's building control team 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.

Local questions answered

What happens at the survey visit in Bournemouth?

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.

Do you cover Bournemouth for steel columns & posts?

Yes. We carry out steel columns & posts in Bournemouth and the BH1, BH2, BH3, BH4 and BH5 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

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.

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.

What is the difference between a column and a padstone?

A padstone is a block bedded into a wall to spread a beam's load into the masonry beneath. A column replaces the need for a wall altogether, carrying the load down to its own foundation. Where the wall below a beam end is too weak for a padstone, the engineer may call for a column instead.

Can I stay at home while the work is done in Bournemouth?

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.
