The Celsius 355 CHS 21.3×2.6 entry provides a concise reference for a circular hollow section (CHS), including its diameter, wall thickness, sectional area, and unit weight. These values are useful when reviewing steel shape schedules, preparing drawings, or comparing section-property references.
The entry also identifies EN 10210-2:2006-04 as the referenced standard for dimensions, tolerances, and sectional properties. Use this page alongside related CHS section properties, structural steel terminology, and CAD/DWG reference resources when developing or checking project documentation.

Thickness : 2.6 mm
Sectional Area : 1.53 cm2
Unit Weight : 1.2 kg/m
Celsius 355 CHS reference overview
A circular hollow section has a round hollow profile. In this entry, the section designation identifies the Celsius 355 CHS profile and the supplied dimensions describe its basic geometry. The listed sectional area and unit weight provide additional reference data for material takeoff, drawing review, and preliminary comparison with other steel shapes.
What the listed properties mean
- Diameter: the stated outside size of the circular section.
- Thickness: the stated wall thickness of the hollow section.
- Sectional area: the steel area represented by a transverse cut through the section.
- Unit weight: the listed mass per unit length for the profile.
Standard and drawing reference
The source identifies EN 10210-2:2006-04 for dimensional tolerances, dimensions, and sectional properties of hot-finished structural hollow sections. The downloadable DWG file can support drafting workflows and shape-library checks, but drawing users should confirm units, insertion settings, layer conventions, and project-specific detailing requirements before use.
For design work, treat the values on this page as a reference to be checked against the governing project specification and the applicable design basis. Section selection, connection detailing, stability checks, and resistance calculations require engineering verification.
