SHS 15x15x1.1 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 15x15 cal 18 (México) · Caño estructural 15x15 (Argentina)

The SHS 15x15x1.1 steel profile weighs 0.5 kg/m (0.31 lb/ft), has a depth of 15 mm (0.59 in), flange width 15 mm (0.59 in). Cross-sectional area: 58.044 mm². Moment of inertia Ix = 0.182 cm⁴, Iy = 0.182 cm⁴.
