CHS 54x11 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 54x11 steel profile weighs 11.7 kg/m (7.84 lb/ft). Cross-sectional area: 1,485.973 mm². Moment of inertia Ix = 36.592 cm⁴, Iy = 36.592 cm⁴.
