RHS 100x75x2.25 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 100x75 cal 14 (México) · Caño estructural 100x75 (Argentina)

The RHS 100x75x2.25 steel profile weighs 5.9 kg/m (3.98 lb/ft), has a depth of 100 mm (3.94 in), flange width 75 mm (2.95 in). Cross-sectional area: 754.213 mm². Moment of inertia Ix = 110.093 cm⁴, Iy = 70.909 cm⁴.
