How long does RSJ and steel i beam design take in Birmingham?
Most RSJ and steel i beam wall removal calculations are completed within 24 to 72 hours once we have your drawings, measurements and photos. Loft and extension packages usually take three to five working days.
Do your RSJ designs meet Building Control requirements?
Yes. Every project includes full structural calculations Birmingham prepared to current UK standards (Eurocodes and BS). We provide a pack your Building Control officer — Birmingham City, Solihull Council or a private inspector — can review immediately.
What information do you need for an RSJ quote?
We ask for your project postcode, a short description of the work, clear photos and basic measurements of the wall or opening. Any architect plans or sketches are helpful but not essential. 3m and 5m RSJ spans can usually be quoted within a few hours.
Can you design RSJs and steel i beams from photos only?
Many domestic RSJ and steel i beam projects can be designed from good quality photos, measurements and existing plans. Where the structure is complex or unclear we may suggest a site visit before finalising the calculations.
How much does RSJ design cost in Birmingham?
Our fixed fees for RSJ design Birmingham: wall removal RSJ from £245 (3m span) to £295 (5m span), extension steel i beams from £345, loft conversion RSJ packages from £395. Fees are confirmed before we start and cover all calculations, drawings and Building Control support. No unexpected extras.
What is the difference between an RSJ and steel i beams in Birmingham?
An RSJ (Rolled Steel Joist) and a steel i beam are the same product — a steel section with an I-shaped cross-section used to span across an opening or carry load. 'RSJ' is the older British term still widely used by builders and homeowners in Birmingham; 'steel i beam' or 'Universal Beam (UB)' is the more current description. Our steel i beams Birmingham and RSJ design service covers both — same calculation, same Building Control pack, same fixed fee.
What size steel i beam do I need for a 3m or 5m span in Birmingham?
The exact steel i beam size depends on the loads above, but as a typical guide: a 3m RSJ carrying a standard domestic floor is often a 152x89 or 178x102 UB; a 5m RSJ with two floors above typically needs a 203x133 or 254x102 UB. Every project is different and a proper calculation is needed for Building Control. Our RSJ design Birmingham service covers the full check from £245.
