RHS 70x25x2.5 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 70x25 cal 13 (México) · Caño estructural 70x25 (Argentina)

The RHS 70x25x2.5 steel profile weighs 3.4 kg/m (2.29 lb/ft), has a depth of 70 mm (2.76 in), flange width 25 mm (0.98 in). Cross-sectional area: 433.905 mm². Moment of inertia Ix = 23.769 cm⁴, Iy = 4.549 cm⁴.
