Accessible tools for every engineer.
Our mission is to make professional structural engineering tools accessible to every engineer and student, regardless of location or budget. Whether you're in a top firm or studying from your phone, you should have access to reliable, transparent calculation tools.
Everything you need to calculate.
Free Calculators
Beam analysis, unit conversion, rebar sizing and more — all free, no login required.
Excel Templates
Professional design sheets for beams, slabs, columns and footings. Coming soon.
Code Support
Every tool supports both Eurocode (EC) and ACI, so you can switch standards instantly.
Both Unit Systems
Full SI and Imperial support across all calculators and templates.
No black boxes.
Our calculators use classical elastic beam theory and code-compliant formulas. Every result is traceable — we show the equations behind every output so you can verify the engineering, not just trust the software.
