SHS 40x40x4 Tata Steel Hybox · Weight & Dimensions

Tata Steel Hybox · 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 4.2 kg/m (2.82 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 534.796 mm². Moment of inertia Ix = 11.075 cm⁴, Iy = 11.075 cm⁴.

Cross-section (not to scale)

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