SHS 120x8
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.
Also known as: PTR 120x120 (México) · Caño estructural 120x120 (Argentina)
The SHS 120x8 steel profile weighs 26.3 kg/m (17.67 lb/ft), has a depth of 120 mm (4.72 in), flange width 120 mm (4.72 in). Cross-sectional area: 3,584 mm². Moment of inertia Ix = 753.12 cm⁴, Iy = 753.12 cm⁴.
