RHS 100x60x3 GOST · Weight & Dimensions

GOST, 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 100x60 cal 11 (México) · Caño estructural 100x60 (Argentina)

The RHS 100x60x3 steel profile weighs 7.1 kg/m (4.75 lb/ft), has a depth of 100 mm (3.94 in), flange width 60 mm (2.36 in). Cross-sectional area: 900.823 mm². Moment of inertia Ix = 120.575 cm⁴, Iy = 54.647 cm⁴.
