Structural intelligence for patio design and quoting
Use this page to run fast preliminary engineering checks before certification. It helps align quoting, detailing and constructability while keeping your final certifier workflow efficient.
Steel-first modelling
Optimise RHS/SHS rafters, beams and posts with quick checks that mirror real-world patio engineering workflows.
Wind + gravity assumptions
Apply regional wind intent and gravity effects to estimate reactions and uplift before formal certification.
Certification handover
Generate a clear engineering summary to share with the certifying engineer for Form 15/16 workflows.
Interactive engineering calculator
Adjust spans and load assumptions to get indicative member sizing and reactions. Final sign-off must still come from your certified structural engineer.
Preliminary guidance only
Use this output to prepare briefs and accelerate formal certification.
Design inputs
Indicative values only. Confirm with a certified structural engineer.
Indicative output
For concept and quoting guidance only.
Wind: 0.735 kPa
Ultimate: 1.401 kPa
Uplift: 0.553 kPa
