Steel Section Catalog
SHS 75x3
BR — 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.
The SHS 75x3 steel profile weighs 6.5 kg/m (4.36 lb/ft), has a depth of 75 mm (2.95 in), flange width 75 mm (2.95 in). Cross-sectional area: 864 mm². Moment of inertia Ix = 74.78 cm⁴, Iy = 74.78 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
