SHS 127x127x4.78 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 127x127 cal 6 (México) · Caño estructural 127x127 (Argentina)

The SHS 127x127x4.78 steel profile weighs 17.9 kg/m (12.02 lb/ft), has a depth of 127 mm (5.00 in), flange width 127 mm (5.00 in). Cross-sectional area: 2,278.007 mm². Moment of inertia Ix = 559.629 cm⁴, Iy = 559.629 cm⁴.
