RHS 40x30x1.5 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 40x30 cal 16 (México) · Caño estructural 40x30 (Argentina)

The RHS 40x30x1.5 steel profile weighs 1.5 kg/m (1.03 lb/ft), has a depth of 40 mm (1.57 in), flange width 30 mm (1.18 in). Cross-sectional area: 195.206 mm². Moment of inertia Ix = 4.378 cm⁴, Iy = 2.806 cm⁴.
