About our RSJ installation service in Grangemouth

Grangemouth has a mix of housing, and RSJ installation needs a slightly different approach in each. We also cover the surrounding towns and villages in Falkirk. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

People still call almost any steel beam in a house an RSJ, even though the sections fitted today are usually universal beams with parallel flanges. Whatever the name, the job is the same: a length of structural steel, made to an engineer's specification, carrying floors, walls or roof over a space where support used to be.

Worth knowing before you start

  • Steel for internal use is normally delivered with a primer coat to protect it during installation. Beams in damp positions, within external walls or exposed outside need a more robust coating or galvanising, as the engineer specifies.
  • Structural steel comes in recognised grades, and the engineer's drawing states which grade the calculations assume. The steel supplied matches that specification, and the delivery paperwork is kept so building standards can see what has been fitted.
  • Floor joists can rest on the bottom flange, hang from timber packers bolted into the web, or be notched to sit over the steel. The engineer specifies the connection, and it affects how flush the finished ceiling can be.
  • Fitting an RSJ to support a wall, floor or roof is building work needing approval through building standards, or a building warrant in Scotland. Cost depends on the steel specified, fabrication, access, propping and finishing, each shown separately in the quote.
  • Delivery can make or break an RSJ job. A long beam has to turn through a front door, along a hallway and past the stairs, so routes are measured at the survey and alternatives such as a window opening are planned early.

Four stages, one team

  1. Survey in Grangemouth

    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.

  2. 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.

  3. Building warrant

    A building warrant is applied for from Falkirk Council, and work starts only once the warrant has been granted.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building standards inspects it, and we make good.

Building rules for Grangemouth

Steel beam work in Grangemouth needs a building warrant from Falkirk Council. The structural design is part of the application, and the council's building standards team accepts the completion certificate once the work is done as approved.

There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.

RSJ installation in Grangemouth: your questions

Can you work on older or listed homes in Grangemouth?

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.

Who approves RSJ installation in Grangemouth?

Structural work in Grangemouth needs a building warrant from Falkirk Council, granted before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

How heavy is an RSJ and how is it lifted?

Weight varies widely with the section and length, from beams a small team can carry to steels needing mechanical lifting. The lift is planned at the survey, using enough people, trolleys and suitable lifting equipment so the beam goes up safely and level onto both bearings.

What is included in an RSJ supply and fit price?

Our itemised written quote sets out the calculations, building standards, steel and fabrication, delivery, lifting, padstones, propping, labour, fire protection and making good as separate lines. Once the specification and scope are agreed, the price is fixed in writing, so you know the full cost before work starts.

Does an RSJ need to be painted or boxed in?

Usually it needs fire protection, most often by boxing in with fire-rated plasterboard and skimming. If you want the steel on show, an intumescent paint system can be applied to the specified thickness and then top-coated in your chosen colour. The fabrication primer is not fire protection on its own.
