RHS 80x60x1.5 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 80x60 cal 16 (México) · Caño estructural 80x60 (Argentina)

The RHS 80x60x1.5 steel profile weighs 3.2 kg/m (2.14 lb/ft), has a depth of 80 mm (3.15 in), flange width 60 mm (2.36 in). Cross-sectional area: 405.206 mm². Moment of inertia Ix = 38.233 cm⁴, Iy = 24.656 cm⁴.
