CHS 38.1x2.0
EN — 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.
The CHS 38.1x2.0 steel profile weighs 1.8 kg/m (1.20 lb/ft). Cross-sectional area: 226.8 mm². Moment of inertia Ix = 3.71 cm⁴, Iy = 3.71 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
