SHS 25x25x1.1 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 25x25 cal 18 (México) · Caño estructural 25x25 (Argentina)

The SHS 25x25x1.1 steel profile weighs 0.8 kg/m (0.54 lb/ft), has a depth of 25 mm (0.98 in), flange width 25 mm (0.98 in). Cross-sectional area: 102.044 mm². Moment of inertia Ix = 0.956 cm⁴, Iy = 0.956 cm⁴.
