FL · EN 10058
FL 50×10 is a hot rolled steel flat bar per EN 10058: width 50 mm, thickness 10 mm, weight 3.9 kg/m, cross-section area 5 cm², moment of inertia Iy = 10.4 cm⁴, elastic section modulus Wel,y = 4.2 cm³.
Check to EN 1993-1-1
Enter the design loads and the section is checked for bending, shear and compression with flexural buckling.
Yield strength is taken from the product standard for the governing thickness, so above 16 mm it is lower than the nominal grade. Simplified checks per EN 1993-1-1, without M+N+V interaction, without lateral-torsional buckling and without web shear buckling. Verify with a full design.
