CHS 245x14 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 245x14 steel profile weighs 79.8 kg/m (53.60 lb/ft). Cross-sectional area: 10,159.911 mm². Moment of inertia Ix = 6,801.679 cm⁴, Iy = 6,801.679 cm⁴.
