SHS 80x80x6.3 Iberian tables · Weight & Dimensions

Iberian tables, 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 4 (México) · Caño estructural 80x80 (Argentina)

The SHS 80x80x6.3 steel profile weighs 13.8 kg/m (9.26 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,755.029 mm². Moment of inertia Ix = 153.998 cm⁴, Iy = 153.998 cm⁴.
