CHS 193.7x3.5 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 193.7x3.5 steel profile weighs 16.4 kg/m (11.03 lb/ft). Cross-sectional area: 2,091.358 mm². Moment of inertia Ix = 946.033 cm⁴, Iy = 946.033 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.5 mm ≈ 10 gauge (Manufacturers Standard Gage)
