SHS 45x45x0.9 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 18 (México) · Caño estructural 45x45 (Argentina)

The SHS 45x45x0.9 steel profile weighs 1.2 kg/m (0.83 lb/ft), has a depth of 45 mm (1.77 in), flange width 45 mm (1.77 in). Cross-sectional area: 156.674 mm². Moment of inertia Ix = 5.044 cm⁴, Iy = 5.044 cm⁴.
