CHS 127x28 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 127x28 steel profile weighs 68.4 kg/m (45.94 lb/ft). Cross-sectional area: 8,708.495 mm². Moment of inertia Ix = 1,152.243 cm⁴, Iy = 1,152.243 cm⁴.
