CHS 73x5 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 73x5 steel profile weighs 8.4 kg/m (5.63 lb/ft). Cross-sectional area: 1,068.142 mm². Moment of inertia Ix = 62.072 cm⁴, Iy = 62.072 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
