SHS 115x115x6.4 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 115x115 cal 3 (México) · Caño estructural 115x115 (Argentina)

The SHS 115x115x6.4 steel profile weighs 21.0 kg/m (14.11 lb/ft), has a depth of 115 mm (4.53 in), flange width 115 mm (4.53 in). Cross-sectional area: 2,674.679 mm². Moment of inertia Ix = 514.991 cm⁴, Iy = 514.991 cm⁴.
