CHS 57x1.2 Hiasa · Weight & Dimensions

Hiasa, 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 57x1.2 steel profile weighs 1.6 kg/m (1.11 lb/ft). Cross-sectional area: 210.361 mm². Moment of inertia Ix = 8.191 cm⁴, Iy = 8.191 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.2 mm ≈ 18 gauge (Manufacturers Standard Gage)
