SHS 45x45x1.6 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 45x45 cal 16 (México) · Caño estructural 45x45 (Argentina)

The SHS 45x45x1.6 steel profile weighs 2.1 kg/m (1.43 lb/ft), has a depth of 45 mm (1.77 in), flange width 45 mm (1.77 in). Cross-sectional area: 271.167 mm². Moment of inertia Ix = 8.407 cm⁴, Iy = 8.407 cm⁴.
