SHS 178x178x4.8 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 178x178 cal 6 (México) · Caño estructural 178x178 (Argentina)

The SHS 178x178x4.8 steel profile weighs 25.4 kg/m (17.09 lb/ft), has a depth of 178 mm (7.01 in), flange width 178 mm (7.01 in). Cross-sectional area: 3,266.107 mm². Moment of inertia Ix = 1,617.862 cm⁴, Iy = 1,617.862 cm⁴.
