SHS 80x80x5.6 Tecnometal · Weight & Dimensions
Tecnometal, cold-formed sections (Brazil) · 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 (México) · Caño estructural 80x80 (Argentina)
The SHS 80x80x5.6 steel profile weighs 12.4 kg/m (8.37 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,585.801 mm². Moment of inertia Ix = 142.394 cm⁴, Iy = 142.394 cm⁴.
