About RSJ.info
Practical, clear guidance on RSJ beams for homeowners, builders, and structural professionals.
What We Do
RSJ.info was created to bridge the gap between complex structural engineering and the real-world questions people ask when planning renovations. We write in plain English, back our content with industry standards, and always point readers toward the right professionals when on-site work is needed.
Our calculators, load tables, and installation guides are designed to help you budget, plan, and communicate effectively with engineers and builders. They are not a substitute for a chartered structural engineer's calculations or formal Building Control approval.
Our Mission
We believe that good information leads to safer buildings. Whether you are removing a load-bearing wall for an open-plan kitchen, adding a loft conversion, or pricing steel for a garage project, we do our best to give you accurate, up-to-date guidance.
Every article and calculator on this site is reviewed by qualified professionals with hands-on experience in residential and light commercial steelwork. If you are undertaking structural work, we strongly recommend hiring a chartered structural engineer and obtaining Building Control approval before any beams are ordered or installed.
