CHS 219x6.35 IMCA · Weight & Dimensions

IMCA, 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 219x6.35 steel profile weighs 33.3 kg/m (22.38 lb/ft). Cross-sectional area: 4,242.179 mm². Moment of inertia Ix = 2,400.031 cm⁴, Iy = 2,400.031 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6.35 mm ≈ 3 gauge (Manufacturers Standard Gage)
