The Celsius 355 CHS 168.3×6.3 reference identifies a circular hollow structural section and summarizes its published dimensional and mass data. Use the source values below when checking drawings, comparing section references, or preparing preliminary steelwork documentation.
This page also provides context for reading the section designation, understanding the role of EN 10210-2, and accessing the associated DWG file. For related terminology, see the site’s references on circular hollow sections, section properties, and structural steel detailing.
Celsius 355 CHS 168.3×6.3
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 : 168.3 mm
Thickness : 6.3 mm
Sectional Area : 32.1 cm2
Unit Weight : 25.2 kg/m
How to read the CHS designation
CHS means circular hollow section. The designation identifies a hollow round steel profile by its nominal outside diameter and wall thickness. In this reference, those dimensions are shown directly in the source data, together with the calculated section area and unit weight.
What the listed properties mean
- Diameter: the stated outside size of the circular profile.
- Thickness: the nominal wall thickness used to identify the section.
- Sectional area: the steel area represented by a transverse cut through the section. It is used in calculations such as axial resistance, subject to the applicable design method and verification requirements.
- Unit weight: the mass per unit length shown for estimating material quantities, handling requirements, and drawing schedules.
Standard and CAD reference
The cited EN 10210-2 reference provides the dimensional, tolerance, and sectional-property framework for hot-finished structural hollow sections. The related DWG download can support drafting and coordination workflows, but downloaded geometry should be checked against the project’s governing specification before fabrication or construction use.
For broader study, link this page to resources covering EN 10210 hollow sections, CHS connections, steel section notation, and DWG steel details. Section data alone does not establish member capacity or connection adequacy; those decisions require project-specific engineering verification.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section, a round structural steel profile with a hollow interior.
What information is provided for this Celsius 355 section?
The source lists the diameter, wall thickness, sectional area, and unit weight for the referenced section.
What is EN 10210-2 used for?
EN 10210-2 provides the referenced dimensional, tolerance, and sectional-property framework for hot-finished structural hollow sections. It should be read with the applicable material and delivery requirements.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference. Confirm dimensions, tolerances, material requirements, connection details, and project-specific revisions before using it for fabrication or construction.
Does the section listing prove structural suitability?
No. The listed properties are reference data only. Member design, stability, connection behavior, corrosion allowances, and other project conditions require verification by a qualified engineer.
