RHS 300x200x6 · Weight & Dimensions

EN — 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 300x200 cal 4 (México) · Caño estructural 300x200 (Argentina)

The RHS 300x200x6 steel profile weighs 44.5 kg/m (29.90 lb/ft), has a depth of 300 mm (11.81 in), flange width 200 mm (7.87 in). Cross-sectional area: 5,856 mm². Moment of inertia Ix = 7,575.67 cm⁴, Iy = 4,052.79 cm⁴.
