About Steel Beam Checker
Indicative UK steel beam triage: span and load to the UC/UB range typically specified, then straight to an engineer for the real calcs.
What is on this site
One question, "steel beam calculator uk", answered with a checker that works on the page with no account, 3 guides on the questions around it, a data table you can cite (the figures and their method), and the sources every figure rests on.
- How much does an RSJ cost? Steel, calcs and fitting (2026): Typical 2026 UK prices: a small domestic RSJ is £150–£300 supplied, engineer's calcs £250–£500, and a typical installed wall opening lands at £1,600–£3,200 all in.
- What size RSJ do I need? The honest answer, span by span: Why there is no lookup answer for RSJ size: loads, deflection, bearing and padstones decide it. What engineers typically specify per span, and how to get real calcs.
- Steel beam calculations for building control: what is required: Building control needs structural calculations before it signs off a beam: what the calcs must show, full plans vs building notice, typical fees and the completion cert.

Steel Beam Checker is an independent information site operated by Ellul Solutions Ltd. It is not affiliated with any engineering institution, steel supplier or building control body. Nothing on this site is structural engineering advice and no output here is a beam specification: sizing is a structural engineer's calculation under BS EN 1993 and the Building Regulations, and building control requires those calculations. Never order steel from this checker.
