CHS 19x1.0

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 19x1.0 steel profile weighs 0.4 kg/m (0.30 lb/ft). Cross-sectional area: 56.5 mm². Moment of inertia Ix = 0.23 cm⁴, Iy = 0.23 cm⁴.
