SHS 50.8x50.8x3.81 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 50.8x50.8 cal 8 (México) · Caño estructural 50.8x50.8 (Argentina)

The SHS 50.8x50.8x3.81 steel profile weighs 5.3 kg/m (3.58 lb/ft), has a depth of 50.8 mm (2.00 in), flange width 50.8 mm (2.00 in). Cross-sectional area: 678.745 mm². Moment of inertia Ix = 24.255 cm⁴, Iy = 24.255 cm⁴.
