SHS 80x80x3 SAISC · Weight & Dimensions

SAISC, 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 80x80 cal 11 (México) · Caño estructural 80x80 (Argentina)

The SHS 80x80x3 steel profile weighs 7.1 kg/m (4.75 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 900.823 mm². Moment of inertia Ix = 87.843 cm⁴, Iy = 87.843 cm⁴.
