STRUCTURA PRO - Steel Eurocode

STRUCTURA PRO is a professional steel structure calculator built for engineers, structural fabricators, metalworkers, boilermakers, industrial draftsmen, and engineering students in metal construction.

━━━ FEATURES ━━━

▸ BENDING — 18 load cases
• Simply supported, fixed, cantilever beams
• Point loads, distributed loads, concentrated moments
• Calculation of bending moments, shear forces, stresses, deflections
• Automatic conformity check (strength + deflection)
• Customizable deflection criterion (L/250, L/300, L/500...) or free

▸ SECTIONS — 25+ standardized steel profiles
• IPE, HEA, HEB, IPN
• UPE, UPN, UAP
• Equal/unequal angles, 45° angles
• Round, square, rectangular tubes
• Round bars, square bars, custom sections
• All properties: Iy, Iz, Wy, Wz, Sy, Sz, linear mass, surface

▸ MATERIALS

Standardized profiles (IPE, HEA, HEB, IPN, UPE, UAP, UPN):
• Construction steels: S235, S275, S355

Parametric sections (tubes, rectangles, round bars, angles, etc.) — all materials available:
• Steels: S235, S275, S355
• Stainless: 304L, 316L
• Aluminums: 2024-T3, 2618A-T6, 5083-H111, 5086-H24, 6060-T6, 6082-T6
• Titanium: TA6V (Grade 5), Ti Grade 2


▸ PROFILE OPTIMIZATION
• Automatically finds the lightest profile meeting your constraints
• Criterion by safety factor (default 3.0) or by deflection ratio
• Saves sizing time

▸ CUT-LIST OPTIMIZATION
• Tree-based algorithm that minimizes waste
• Customizable kerf width
• Acceptable waste configurable
• Calculates number of bars needed + yield
• Piece-by-piece detail for each bar

▸ CART & EXPORT
• Multi-profile parts list with project name
• Total mass and paint surface calculation
• Excel export (CSV-compatible format)
• Native PDF printing via browser

▸ MULTILINGUAL — Available in 4 languages
• English, French, Italian, Spanish
• Automatic detection based on phone language
• FR / EN / IT / ES button at the bottom of the app for instant switching

▸ 100% OFFLINE
• No Internet connection required after installation
• No data collected, no account, no advertising
• Your calculations stay on your device
• Ideal for the worksite, workshop, or on the go

━━━ TARGET AUDIENCE ━━━

• Structural fabricators in metal
• Steel/aluminum structure builders
• Engineering offices in metal construction
• Metalworkers / locksmiths
• Boilermakers
• Students in vocational training (BTS, Bac Pro Metalwork)
• Industrial draftsmen and mechanical designers

━━━ ACCURACY ━━━

All formulas come from classical structural mechanics (strength of materials). Material values comply with EN 10025 (steel) and EN 573-3 (aluminum) standards.

STRUCTURA PRO provides indicative results to assist sizing. Calculations must be verified by a qualified engineering office for any real application.

━━━ WHY STRUCTURA PRO? ━━━

→ Fast: mobile-first interface, instant results
→ Accurate: verified formulas, exact catalog values
→ Reliable: 100% offline, no network dependency
→ Practical: cut optimization rare on mobile = differentiator on site
→ Compact: no heavy installation, pure calculation app

Designed by an engineer, for engineers.
