SHS · EN 10210 · hot finished
SHS 300/12.5 is a hot-finished square hollow section per EN 10210: side 300 mm, wall thickness 12.5 mm, weight 111.5 kg/m, cross-section area 142.1 cm², moment of inertia Iy = 19440 cm⁴, elastic section modulus Wel,y = 1296 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.
