Steel Beam & RSJ Calculations UK | The Beam Doctor
Chartered Structural Engineer (CEng MIStructE)

Structural Engineering Services — West Yorkshire

Chartered expertise for domestic renovations. We don't just "size beams"—we engineer the safety of your largest asset.

A Note on 'Builder Estimates'

If your builder sizes a steel beam based on "experience" alone, they are violating **Building Regulations Part A**. Without an Engineer's signature, your home insurance may be void, and you will face legal issues during any future property sale.
