CHS 48.3x3.2
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 48.3x3.2 steel profile weighs 3.6 kg/m (2.39 lb/ft). Cross-sectional area: 453.4 mm². Moment of inertia Ix = 11.59 cm⁴, Iy = 11.59 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.2 mm ≈ 10 gauge (Manufacturers Standard Gage)
