SHS 20x20x2 Cintac · Weight & Dimensions

Cintac, cold-formed sections · 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 20x20x2 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: 133.699 mm². Moment of inertia Ix = 0.692 cm⁴, Iy = 0.692 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
