SHS 50x3
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 50x50 cal 11 (México) · Caño estructural 50x50 (Argentina)
The SHS 50x3 steel profile weighs 4.3 kg/m (2.86 lb/ft), has a depth of 50 mm (1.97 in), flange width 50 mm (1.97 in). Cross-sectional area: 564 mm². Moment of inertia Ix = 20.85 cm⁴, Iy = 20.85 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
