SHS 80x80x2.5 Hiasa · Weight & Dimensions
Hiasa, 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 80x80 cal 13 (México) · Caño estructural 80x80 (Argentina)
The SHS 80x80x2.5 steel profile weighs 6.0 kg/m (4.01 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 758.905 mm². Moment of inertia Ix = 75.147 cm⁴, Iy = 75.147 cm⁴.
