SHS 40x3
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 40x40 cal 11 (México) · Caño estructural 40x40 (Argentina)
The SHS 40x3 steel profile weighs 3.3 kg/m (2.22 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 444 mm². Moment of inertia Ix = 10.2 cm⁴, Iy = 10.2 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
