CHS 42.2x4 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 42.2x4 steel profile weighs 3.8 kg/m (2.53 lb/ft). Cross-sectional area: 480.035 mm². Moment of inertia Ix = 8.852 cm⁴, Iy = 8.852 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
