SHS 63.5x63.5x3.18 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 63.5x63.5 cal 11 (México) · Caño estructural 63.5x63.5 (Argentina)

The SHS 63.5x63.5x3.18 steel profile weighs 5.8 kg/m (3.91 lb/ft), has a depth of 63.5 mm (2.50 in), flange width 63.5 mm (2.50 in). Cross-sectional area: 741.229 mm². Moment of inertia Ix = 44.133 cm⁴, Iy = 44.133 cm⁴.
