SHS 177.8x177.8x7.95 CISC · Weight & Dimensions

CISC, 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 177.8x177.8 (México) · Caño estructural 177.8x177.8 (Argentina)

The SHS 177.8x177.8x7.95 steel profile weighs 41.1 kg/m (27.63 lb/ft), has a depth of 177.8 mm (7.00 in), flange width 177.8 mm (7.00 in). Cross-sectional area: 5,238.47 mm². Moment of inertia Ix = 2,478.44 cm⁴, Iy = 2,478.44 cm⁴.
