    RSJ universal beams are used where a strong horizontal steel section is needed to support load across an opening or span. At South Steel, we supply RSJ universal beams online for homeowners, self-builders, contractors and trade buyers looking for a straightforward way to order structural steel.

    These sections may be called RSJ beams, steel beams or universal beams, depending on the drawings, steel schedule or specification. They are often used in wall removals, house extensions, loft conversions, refurbishments and smaller commercial projects.

    RSJ Universal Beams for Structural Support

    RSJ universal beams are commonly specified where part of a building needs horizontal support, such as supporting masonry above an opening, strengthening a floor or forming part of a wider steel frame.

    RSJ universal beams can also be used in landscaping and external works, including as steel sleeper retainer posts for timber sleeper retaining walls where the beam size and installation method are suitable for the project. 

    South Steel lets customers browse available products online, choose the required steel section and order through the website. If your project includes drawings, calculations or a steel schedule, the team can provide practical support before you order.

    For load-bearing work, customers should always follow their structural engineer’s specification, drawings or calculations. South Steel can supply the steel, but the correct RSJ universal beams, sizes and specifications should be confirmed by the qualified professional responsible for the design.
