CHS 50.8x1.5
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 50.8x1.5 steel profile weighs 1.8 kg/m (1.23 lb/ft). Cross-sectional area: 232.3 mm². Moment of inertia Ix = 7.06 cm⁴, Iy = 7.06 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
