RHS 90x30x1.5 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Brazil) · 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 90x30 cal 16 (México) · Caño estructural 90x30 (Argentina)

The RHS 90x30x1.5 steel profile weighs 2.7 kg/m (1.82 lb/ft), has a depth of 90 mm (3.54 in), flange width 30 mm (1.18 in). Cross-sectional area: 345.206 mm². Moment of inertia Ix = 32.928 cm⁴, Iy = 5.854 cm⁴.
