SHS 203.2x203.2x6.35 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 203.2x203.2 cal 3 (México) · Caño estructural 203.2x203.2 (Argentina)

The SHS 203.2x203.2x6.35 steel profile weighs 38.4 kg/m (25.82 lb/ft), has a depth of 203.2 mm (8.00 in), flange width 203.2 mm (8.00 in). Cross-sectional area: 4,896.151 mm². Moment of inertia Ix = 3,127.866 cm⁴, Iy = 3,127.866 cm⁴.
