CHS 19x1.5
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 19x1.5 steel profile weighs 0.6 kg/m (0.43 lb/ft). Cross-sectional area: 82.5 mm². Moment of inertia Ix = 0.32 cm⁴, Iy = 0.32 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
