SHS 70x70x1.2 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 70x70 cal 18 (México) · Caño estructural 70x70 (Argentina)

The SHS 70x70x1.2 steel profile weighs 2.6 kg/m (1.72 lb/ft), has a depth of 70 mm (2.76 in), flange width 70 mm (2.76 in). Cross-sectional area: 326.532 mm². Moment of inertia Ix = 25.612 cm⁴, Iy = 25.612 cm⁴.
