CHS 139.7x6 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 139.7x6 steel profile weighs 19.8 kg/m (13.29 lb/ft). Cross-sectional area: 2,520.186 mm². Moment of inertia Ix = 564.26 cm⁴, Iy = 564.26 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6 mm ≈ 4 gauge (Manufacturers Standard Gage)
