CHS 42.8x3 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 42.8x3 steel profile weighs 2.9 kg/m (1.98 lb/ft). Cross-sectional area: 375.106 mm². Moment of inertia Ix = 7.469 cm⁴, Iy = 7.469 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
