CHS 26.7x2.87 Hylsa · Weight & Dimensions

Hylsa, 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 26.7x2.87 steel profile weighs 1.7 kg/m (1.13 lb/ft). Cross-sectional area: 214.86 mm². Moment of inertia Ix = 1.547 cm⁴, Iy = 1.547 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.87 mm ≈ 11 gauge (Manufacturers Standard Gage)
