RHS · EN 10210 · hot finished
RHS 300×200/6.3 is a hot-finished rectangular hollow section per EN 10210: height 300 mm, width 200 mm, wall thickness 6.3 mm, weight 47.9 kg/m, cross-section area 61 cm², moment of inertia Iy = 7829 cm⁴, elastic section modulus Wel,y = 521.9 cm³.
Check to EN 1993-1-1
Enter the design loads and the section is checked for bending, shear and compression with flexural buckling.
The compression check is not available: in uniform compression the section is class 4 and effective properties per EN 1993-1-5 are required. Bending and shear are unaffected.
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.
