CHS 26.7x2.54 CISC · Weight & Dimensions

CISC, 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 26.7x2.54 steel profile weighs 1.5 kg/m (1.01 lb/ft). Cross-sectional area: 192.788 mm². Moment of inertia Ix = 1.422 cm⁴, Iy = 1.422 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.54 mm ≈ 12 gauge (Manufacturers Standard Gage)
