RHS 30x10x0.9 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 30x10 cal 18 (México) · Caño estructural 30x10 (Argentina)

The RHS 30x10x0.9 steel profile weighs 0.5 kg/m (0.35 lb/ft), has a depth of 30 mm (1.18 in), flange width 10 mm (0.39 in). Cross-sectional area: 66.674 mm². Moment of inertia Ix = 0.672 cm⁴, Iy = 0.116 cm⁴.
