CHS 42.4x2.0
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 42.4x2.0 steel profile weighs 2.0 kg/m (1.34 lb/ft). Cross-sectional area: 253.8 mm². Moment of inertia Ix = 5.19 cm⁴, Iy = 5.19 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
