CHS 101.6x3.6 Iberian tables · Weight & Dimensions

Iberian tables, cold-formed sections · Circular Hollow Section

Circular Hollow Sections (CHS) are round tubular profiles with the most efficient cross-section for compression. Used for columns, trusses, and architectural structures.

Also known as: Caño estructural redondo (Argentina)

The CHS 101.6x3.6 steel profile weighs 8.7 kg/m (5.85 lb/ft). Cross-sectional area: 1,108.354 mm². Moment of inertia Ix = 133.237 cm⁴, Iy = 133.237 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.6 mm ≈ 9 gauge (Manufacturers Standard Gage)
