SHS 40x40x1.9 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Brazil) · 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 15 (México) · Caño estructural 40x40 (Argentina)

The SHS 40x40x1.9 steel profile weighs 2.2 kg/m (1.48 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 280.263 mm². Moment of inertia Ix = 6.664 cm⁴, Iy = 6.664 cm⁴.
