CHS 273x6.35 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 273x6.35 steel profile weighs 41.8 kg/m (28.06 lb/ft). Cross-sectional area: 5,319.431 mm². Moment of inertia Ix = 4,730.473 cm⁴, Iy = 4,730.473 cm⁴.

Cross-section (not to scale)

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