CalcSteel

CalcSteel is a complete structural steel engineering platform that runs entirely in your browser — no downloads, no plugins, no login required to start.

WHAT YOU CAN DO: • Model steel structures in a full 3D CAD editor with smart snaps, precise input, and undo/redo • Choose from 640+ steel profiles (AISC, Eurocode EN, Brazilian NBR, Indian IS 808) and assign them with one click • Generate complete structures in seconds using parametric templates (portal frames, warehouses, trusses, lattice columns) • Run finite element analysis with a 6-DOF stiffness matrix solver • Verify members against 5 design codes: AISC 360, Eurocode 3, NBR 8800, AS 4100, and IS 800 • View axial, shear, and moment diagrams • Export professional PDF drawings with your company logo

WHY IT EXISTS: Professional structural engineering software typically costs $3,000–$15,000/year per seat. CalcSteel offers a full editor for free and Pro features starting at $9/month — making legitimate, modern tools accessible to engineers, small firms, and students worldwide.

KEY DIFFERENTIATORS: ? No login required to start modeling ? 100% web-based (Chrome, Firefox, Safari — any OS) ? Available in 6 languages (EN, PT, ES, FR, Arabic, Bengali) ? Supports 5 international design standards ? Free tier includes the full 3D editor

Built for structural engineers who want professional tools without corporate budgets.
