RHS 30x14x0.9 Acindar · Weight & Dimensions

Acindar, 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 30x14 cal 18 (México) · Caño estructural 30x14 (Argentina)

The RHS 30x14x0.9 steel profile weighs 0.6 kg/m (0.39 lb/ft), has a depth of 30 mm (1.18 in), flange width 14 mm (0.55 in). Cross-sectional area: 73.874 mm². Moment of inertia Ix = 0.824 cm⁴, Iy = 0.25 cm⁴.
