SHS 80x80x1.6 Acindar · Weight & Dimensions

Acindar, 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 16 (México) · Caño estructural 80x80 (Argentina)

The SHS 80x80x1.6 steel profile weighs 3.9 kg/m (2.61 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 495.167 mm². Moment of inertia Ix = 50.384 cm⁴, Iy = 50.384 cm⁴.
