CHS 114x5 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 114x5 steel profile weighs 13.4 kg/m (9.03 lb/ft). Cross-sectional area: 1,712.168 mm². Moment of inertia Ix = 254.813 cm⁴, Iy = 254.813 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
