Frequently asked questions
How much does a 4m RSJ cost installed?
A 4m RSJ typically costs £900–£1,280 for materials and labour. On top of that, budget £300–£500 for a structural engineer and £200–£500 for building control.
How much does a steel beam cost per metre?
Supply-only RSJ steel beams cost £50–£100 per metre. Fitting is extra: installed, a 2m span typically costs £650–£840 and a 5m span £1,150–£1,500.
Can I fit an RSJ myself to save money?
No. RSJ installation needs a structural engineer's calculations, building regulations approval and professional installation, and DIY work risks structural failure and invalidating your home insurance.
How long does it take to fit an RSJ?
Standard residential projects typically take 1–2 days. Larger spans or difficult access may take 2–4 days.
