Celsius 355 CHS 60.3×6.3
Celsius 355 Circular Hollow Sections
refer to : EN 10210-2:2006-04
the European standard that specifies tolerances, dimensions, and sectional properties for hot-finished structural hollow sections of non-alloy and fine grain steels. It supports EN 10210-1, which covers technical delivery conditions.
Diameter : 60.3 mm
Thickness : 6.3 mm
Sectional Area : 10.7 cm2
Unit Weight : 8.4 kg/m
How to read the Celsius 355 CHS reference
CHS means circular hollow section. The designation identifies a round structural hollow section, while the size notation describes its outside diameter and wall thickness. These dimensions help distinguish the section from other circular or hollow steel products.
Sectional area and unit weight
The sectional area is a geometric property of the steel material in the cross-section. It is commonly used as an input for engineering checks involving axial force and other section-property calculations, subject to the design method and applicable verification requirements.
The unit weight expresses the listed mass of the section per metre. It is useful for material takeoffs, shipping estimates, support-reaction reviews, and coordination between structural drawings and fabrication information. Actual project quantities may also depend on cuts, fittings, welds, coatings, and connection details.
Standard reference
The source identifies EN 10210-2:2006-04 as the dimensional and sectional-property reference for the listed hot-finished structural hollow section. It should be read together with the associated technical delivery requirements and the project specification. A standard reference does not, by itself, establish that a section is adequate for a particular structural application.
CAD and detailing workflow
The available DWG file can support drafting and model coordination. Before using it in production documents, check the drawing units, layer conventions, insertion scale, title-block information, and the project office’s CAD standards. Link this page to related internal references for CHS terminology, steel section properties, structural connections, and DWG detailing resources.
Reference checklist
- Confirm the diameter and wall thickness against the project material schedule.
- Use the listed sectional area and unit weight consistently with the selected design and estimating workflow.
- Verify material identification, delivery documentation, and fabrication requirements before procurement.
- Review the downloaded DWG before incorporating it into construction or fabrication drawings.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section. It describes a round, hollow steel section used in structural and mechanical detailing contexts.
What does the 60.3×6.3 designation describe?
It identifies the section by its listed diameter and wall thickness. Always compare the designation with the dimensional data shown on the reference page and with the project material schedule.
Why are sectional area and unit weight listed?
Sectional area supports engineering calculations that use cross-sectional geometry, while unit weight supports material estimating and coordination. Neither value alone confirms structural adequacy.
What is the purpose of the EN 10210-2 reference?
It provides the stated reference for dimensions, tolerances, and sectional properties for the applicable hot-finished structural hollow sections. Project teams should also confirm the required technical delivery and design criteria.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference and should be checked against the project drawing standard, required dimensions, connection details, and fabrication information before release.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section, describing a round hollow steel section.
What does the 60.3×6.3 designation describe?
It identifies the listed diameter and wall thickness for the section. Confirm these values against the project schedule before use.
Why are sectional area and unit weight important?
Sectional area supports calculations based on cross-sectional geometry, while unit weight helps with estimating and coordination. They do not replace a complete engineering check.
What is the role of the DWG download?
The DWG supports drafting and coordination. Check its units, scale, layers, and project-specific detailing requirements before incorporating it into issued documents.
