SHS 40x40x0.8 Acindar · Weight & Dimensions

Acindar, cold-formed sections · 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 (México) · Caño estructural 40x40 (Argentina)

The SHS 40x40x0.8 steel profile weighs 1.0 kg/m (0.65 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 123.792 mm². Moment of inertia Ix = 3.149 cm⁴, Iy = 3.149 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 0.8 mm ≈ 18 gauge (Manufacturers Standard Gage)
