SHS 50x50x6.3 Tata Steel Celsius · Weight & Dimensions

Tata Steel Celsius · 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 4 (México) · Caño estructural 50x50 (Argentina)

The SHS 50x50x6.3 steel profile weighs 8.3 kg/m (5.58 lb/ft), has a depth of 50 mm (1.97 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,033.1 mm². Moment of inertia Ix = 32.015 cm⁴, Iy = 32.015 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
