CHS 57x12 GOST · Weight & Dimensions

GOST, 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 57x12 steel profile weighs 13.3 kg/m (8.95 lb/ft). Cross-sectional area: 1,696.46 mm². Moment of inertia Ix = 45.995 cm⁴, Iy = 45.995 cm⁴.
