SHS 40x1.2
EN — Square Hollow Section
Square Hollow Sections (SHS) are tubular profiles with equal sides, ideal for columns and compression members due to their uniform buckling resistance in all directions.
The SHS 40x1.2 steel profile weighs 1.5 kg/m (0.98 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 186.2 mm². Moment of inertia Ix = 4.68 cm⁴, Iy = 4.68 cm⁴.
