RHS 40x10x1.5 Hiasa · Weight & Dimensions

Hiasa, cold-formed sections · Rectangular Hollow Section

Rectangular Hollow Sections (RHS) are tubular profiles with excellent torsional resistance and aesthetic appeal. Used for columns, trusses, and exposed structural elements.

Also known as: PTR 40x10 cal 16 (México) · Caño estructural 40x10 (Argentina)

The RHS 40x10x1.5 steel profile weighs 1.1 kg/m (0.71 lb/ft), has a depth of 40 mm (1.57 in), flange width 10 mm (0.39 in). Cross-sectional area: 135.206 mm². Moment of inertia Ix = 2.153 cm⁴, Iy = 0.215 cm⁴.
