SHS 20x2
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 20x20 cal 15 (México) · Caño estructural 20x20 (Argentina)
The SHS 20x2 steel profile weighs 1.1 kg/m (0.71 lb/ft), has a depth of 20 mm (0.79 in), flange width 20 mm (0.79 in). Cross-sectional area: 144 mm². Moment of inertia Ix = 0.79 cm⁴, Iy = 0.79 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
