RHS 70x10x1.5 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 70x10 cal 16 (México) · Caño estructural 70x10 (Argentina)

The RHS 70x10x1.5 steel profile weighs 1.8 kg/m (1.19 lb/ft), has a depth of 70 mm (2.76 in), flange width 10 mm (0.39 in). Cross-sectional area: 225.206 mm². Moment of inertia Ix = 10.341 cm⁴, Iy = 0.379 cm⁴.
