CHS 245x36 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 245x36 steel profile weighs 185.6 kg/m (124.69 lb/ft). Cross-sectional area: 23,637.343 mm². Moment of inertia Ix = 13,289.21 cm⁴, Iy = 13,289.21 cm⁴.
