CHS 73x6.3 V&M do Brasil · Weight & Dimensions

V&M do Brasil, hot-rolled 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 73x6.3 steel profile weighs 10.4 kg/m (6.96 lb/ft). Cross-sectional area: 1,320.129 mm². Moment of inertia Ix = 74.069 cm⁴, Iy = 74.069 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
