CHS 54x8 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 54x8 steel profile weighs 9.1 kg/m (6.10 lb/ft). Cross-sectional area: 1,156.106 mm². Moment of inertia Ix = 31.504 cm⁴, Iy = 31.504 cm⁴.
