CHS 245x30 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 245x30 steel profile weighs 159.1 kg/m (106.90 lb/ft). Cross-sectional area: 20,263.273 mm². Moment of inertia Ix = 11,936.334 cm⁴, Iy = 11,936.334 cm⁴.
