SHS 76.2x76.2x4.78 CISC · Weight & Dimensions

CISC, 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 76.2x76.2 cal 6 (México) · Caño estructural 76.2x76.2 (Argentina)

The SHS 76.2x76.2x4.78 steel profile weighs 10.3 kg/m (6.89 lb/ft), has a depth of 76.2 mm (3.00 in), flange width 76.2 mm (3.00 in). Cross-sectional area: 1,306.711 mm². Moment of inertia Ix = 108.479 cm⁴, Iy = 108.479 cm⁴.
