CHS 762x6.35 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 762x6.35 steel profile weighs 118.3 kg/m (79.52 lb/ft). Cross-sectional area: 15,074.548 mm². Moment of inertia Ix = 107,603.485 cm⁴, Iy = 107,603.485 cm⁴.

Cross-section (not to scale)

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