Celsius 355 CHS 139.7×4 reference data
The designation identifies a Celsius 355 circular hollow section with a nominal diameter of 139.7 mm and a wall thickness of 4 mm. The source content lists the corresponding sectional area and unit weight for this section.
- Section type: Circular hollow section, or CHS
- Diameter: 139.7 mm
- Thickness: 4 mm
- Sectional area: 17.1 cm2
- Unit weight: 13.4 kg/m
How to use the listed properties
The diameter and thickness describe the nominal geometry used to identify the section. Sectional area is commonly used when reviewing axial force effects and other calculations that depend on the amount of steel in the cross-section. Unit weight supports material quantity checks, weight estimates, and drafting coordination.
These values should be read together with the project specification, design standard, fabrication requirements, and any applicable tolerances. A tabulated section property does not by itself confirm adequacy for a particular member, connection, stability condition, or construction arrangement.
Applicable standard reference
The source refers to EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. It also identifies EN 10210-1 as covering technical delivery conditions. Refer to the applicable project documentation and current standard requirements when using this reference.
CAD and drafting resource
A DWG file is provided for the Celsius 355 CHS 139.7×4 profile. Use the download for drafting and layout coordination, then verify the geometry and project-specific requirements before issuing production or construction documentation.
