FL · EN 10058
FL 200×12 is a hot rolled steel flat bar per EN 10058: width 200 mm, thickness 12 mm, weight 18.8 kg/m, cross-section area 24 cm², moment of inertia Iy = 800 cm⁴, elastic section modulus Wel,y = 80 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.
