SHS 304.8x304.8x6.35 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 304.8x304.8 cal 3 (México) · Caño estructural 304.8x304.8 (Argentina)

The SHS 304.8x304.8x6.35 steel profile weighs 58.7 kg/m (39.44 lb/ft), has a depth of 304.8 mm (12.00 in), flange width 304.8 mm (12.00 in). Cross-sectional area: 7,476.791 mm². Moment of inertia Ix = 11,021.468 cm⁴, Iy = 11,021.468 cm⁴.
