SHS 220x220x6 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 220x220 cal 4 (México) · Caño estructural 220x220 (Argentina)

The SHS 220x220x6 steel profile weighs 39.6 kg/m (26.60 lb/ft), has a depth of 220 mm (8.66 in), flange width 220 mm (8.66 in). Cross-sectional area: 5,043.292 mm². Moment of inertia Ix = 3,813.36 cm⁴, Iy = 3,813.36 cm⁴.
