RHS · EN 10219 · cold formed
RHS 300×200/12 is a cold-formed rectangular hollow section per EN 10219: height 300 mm, width 200 mm, wall thickness 12 mm, weight 84.8 kg/m, cross-section area 108.1 cm², moment of inertia Iy = 12790 cm⁴, elastic section modulus Wel,y = 852.5 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.
