SHS 70x70x5.49 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 (México) · Caño estructural 70x70 (Argentina)

The SHS 70x70x5.49 steel profile weighs 10.5 kg/m (7.06 lb/ft), has a depth of 70 mm (2.76 in), flange width 70 mm (2.76 in). Cross-sectional area: 1,338.928 mm². Moment of inertia Ix = 90.022 cm⁴, Iy = 90.022 cm⁴.
