CHS 76.2x5 SAISC · Weight & Dimensions

SAISC, 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 76.2x5 steel profile weighs 8.8 kg/m (5.90 lb/ft). Cross-sectional area: 1,118.407 mm². Moment of inertia Ix = 71.221 cm⁴, Iy = 71.221 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
