SHS 25x25x3.4 IMCA · Weight & Dimensions

IMCA, 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 11 (México) · Caño estructural 25x25 (Argentina)

The SHS 25x25x3.4 steel profile weighs 2.1 kg/m (1.41 lb/ft), has a depth of 25 mm (0.98 in), flange width 25 mm (0.98 in). Cross-sectional area: 263.99 mm². Moment of inertia Ix = 1.925 cm⁴, Iy = 1.925 cm⁴.
