About RSJ.info
Independent guides and free planning tools for Rolled Steel Joists — written for homeowners, builders and anyone preparing to speak with a structural engineer.
What We Publish
RSJ.info is an independent online publication. We explain beam sizes, load tables, installation workflows and typical UK / Poland project costs in plain English. Our calculators help with early planning and budgeting. They are not a substitute for stamped structural calculations or Building Control approval.
Every guide is researched from publicly available standards, supplier data and common site practice. Where numbers are estimates (prices, simplified capacities), we say so clearly. If you are removing a load-bearing wall or altering a structure, hire a chartered structural engineer and obtain the required approvals before work starts.
Editorial Standards
- Practical planning content — not marketing fluff
- Clear disclaimers on every calculator and structural guide
- No fake professional licences or invented office addresses
- Corrections welcome — email us if you spot an error
Editorial Team
RSJ.info is maintained by a small editorial team. We are content specialists who research and explain construction topics — we are not a structural engineering practice and we do not provide design sign-off.

Owen Briggs
