This reference identifies the Celsius 355 circular hollow section (CHS) with a 48.3 mm diameter and 5.6 mm wall thickness. It brings together the published section data, the applicable European standard reference, and a downloadable DWG resource for engineering and drafting workflows.
Use the dimensional and section-property values below when checking drawings, comparing hollow sections, or coordinating structural steel details. Design use still requires verification of the applicable material, loading, connection, stability, and code requirements.

How to Read This CHS Reference
A circular hollow section is a round structural steel profile defined by its outside diameter and wall thickness. The listed sectional area and unit weight help identify the section in design calculations, material schedules, estimating, and model coordination.
Dimensions and section properties
The diameter and thickness describe the physical profile, while the sectional area and unit weight provide additional identifiers for engineering checks and documentation. Keep the units shown in the source data when transferring values into calculations or schedules.
Standard reference
The page cites EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. It also identifies the relationship with EN 10210-1, which addresses technical delivery conditions. Review the project specification and governing design requirements before relying on any listed section for a particular application.
CAD and drafting resource
The downloadable DWG can support layout, detailing, and coordination tasks. Treat the drawing as a reference representation and verify scale, units, orientation, and connection details before incorporating it into project documentation.
For related research, connect this page with internal references covering circular hollow sections, structural steel section properties, EN 10210 hollow sections, and steel CAD/DWG resources.
