CHS 50.8x2.0
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 50.8x2.0 steel profile weighs 2.4 kg/m (1.62 lb/ft). Cross-sectional area: 306.6 mm². Moment of inertia Ix = 9.14 cm⁴, Iy = 9.14 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
