SHS 40x40x4 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 40x40 cal 8 (México) · Caño estructural 40x40 (Argentina)

The SHS 40x40x4 steel profile weighs 4.4 kg/m (2.95 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 548.531 mm². Moment of inertia Ix = 11.598 cm⁴, Iy = 11.598 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
