SHS 175x175x4.5 SAISC · Weight & Dimensions

SAISC, 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 175x175 cal 6 (México) · Caño estructural 175x175 (Argentina)

The SHS 175x175x4.5 steel profile weighs 23.7 kg/m (15.91 lb/ft), has a depth of 175 mm (6.89 in), flange width 175 mm (6.89 in). Cross-sectional area: 3,016.852 mm². Moment of inertia Ix = 1,448.831 cm⁴, Iy = 1,448.831 cm⁴.
