SHS 150x150x4.5 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 150x150 cal 6 (México) · Caño estructural 150x150 (Argentina)

The SHS 150x150x4.5 steel profile weighs 20.1 kg/m (13.54 lb/ft), has a depth of 150 mm (5.91 in), flange width 150 mm (5.91 in). Cross-sectional area: 2,566.852 mm². Moment of inertia Ix = 896.299 cm⁴, Iy = 896.299 cm⁴.
