SHS · EN 10219 · cold formed
SHS 350/12 is a cold-formed square hollow section per EN 10219: side 350 mm, wall thickness 12 mm, weight 122.5 kg/m, cross-section area 156.1 cm², moment of inertia Iy = 29050 cm⁴, elastic section modulus Wel,y = 1660 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.
