SHS 105x105x4.8 Açotubo · Weight & Dimensions

Açotubo, 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 105x105 cal 6 (México) · Caño estructural 105x105 (Argentina)

The SHS 105x105x4.8 steel profile weighs 14.6 kg/m (9.84 lb/ft), has a depth of 105 mm (4.13 in), flange width 105 mm (4.13 in). Cross-sectional area: 1,864.507 mm². Moment of inertia Ix = 306.878 cm⁴, Iy = 306.878 cm⁴.
