CHS 48.3x4.5 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 48.3x4.5 steel profile weighs 4.9 kg/m (3.27 lb/ft). Cross-sectional area: 619.208 mm². Moment of inertia Ix = 15.006 cm⁴, Iy = 15.006 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4.5 mm ≈ 7 gauge (Manufacturers Standard Gage)
