UPE/UPN dimensions (height, flange width, web thickness) are fully compliant with Eurocode 3 (EN 1993-1-1), the European design standard for structural steelwork. Eurocode 3 references EN 10279 for section properties and EN 10025-2 for material properties, ensuring seamless integration into designs.
For example:
Eurocode 3 uses S355JR's 355 MPa yield strength and 210 GPa modulus of elasticity to calculate bending capacity and deflection.
Its section tables for UPE/UPN match EN 10279 sizes (e.g., UPE 160: 160 mm height, 65 mm flange width, 6.5 mm web thickness).This alignment simplifies design: engineers can directly size UPE/UPN channels using Eurocode 3 formulas, avoiding adjustments for non-standard sizes. Eurocode 3 also provides rules for connecting channels to other components (e.g., welds, bolts), ensuring structural safety. Compliance with both EN standards and Eurocode 3 is mandatory for EU projects.
