CHS Table — Dimensions, Weight & Section Properties
circular hollow section (CHS) per EN 10219 (cold formed)
All common CHS sizes from CHS 21.3 to CHS 323.9. Each size links to a data sheet listing every standard wall thickness with weight and section properties computed from the exact EN 10219-2 geometry.

Frequently Asked Questions
What is an CHS profile?
CHS is the European circular hollow section (CHS) per EN 10219 (cold formed). Sizes here run from CHS 21.3 to CHS 323.9, each in several wall thicknesses. Hollow sections excel where loads act in more than one direction — torsion, columns, frames — and where a clean closed shape matters.
EN 10219 (cold formed) vs EN 10210 (hot finished) — what is the difference?
Cold formed sections (this table) are shaped from strip at room temperature and have larger corner radii (2t–3t outside); hot finished ones are normalized and have tighter corners, slightly higher mass at the same designation, and better properties for dynamic loading. For ordinary frames and structures, cold formed EN 10219 is the stockholder default.

Each row is one outside size; click it for the full data sheet with every wall thickness — weight per meter, cross-section area, moment of inertia, section modulus, and radius of gyration.
Values are entered from the governing standard’s published tables and cross-checked programmatically against its mass and section formulas before publication. Spotted an error? Write to advertising@metalabout.net — verified corrections ship within days. About
