SHS 101.6x101.6x6.35 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 101.6x101.6 cal 3 (México) · Caño estructural 101.6x101.6 (Argentina)

The SHS 101.6x101.6x6.35 steel profile weighs 18.2 kg/m (12.22 lb/ft), has a depth of 101.6 mm (4.00 in), flange width 101.6 mm (4.00 in). Cross-sectional area: 2,315.511 mm². Moment of inertia Ix = 341.939 cm⁴, Iy = 341.939 cm⁴.
