RHS 200x75x3 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 200x75 cal 11 (México) · Caño estructural 200x75 (Argentina)

The RHS 200x75x3 steel profile weighs 12.5 kg/m (8.39 lb/ft), has a depth of 200 mm (7.87 in), flange width 75 mm (2.95 in). Cross-sectional area: 1,590.823 mm². Moment of inertia Ix = 778.79 cm⁴, Iy = 168.875 cm⁴.
