SHS 80x6
EN — 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 80x6 steel profile weighs 13.3 kg/m (8.94 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,776 mm². Moment of inertia Ix = 163.16 cm⁴, Iy = 163.16 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6 mm ≈ 4 gauge (Manufacturers Standard Gage)
