This reference identifies the Celsius 355 circular hollow section (CHS) with a 26.9 mm outside diameter and 3.2 mm wall thickness. Use the listed section data when coordinating structural steel layouts, checking drawings, or preparing preliminary design information.
The page also provides the applicable EN 10210-2 reference and a CAD download. For a broader understanding of hollow sections, compare this entry with related CHS dimensions, section properties, and steel connection detailing resources.
Celsius 355 CHS 26.9×3.2
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 : 26.9 mm
Thickness : 3.2 mm
Sectional Area : 2.38 cm2
Unit Weight : 1.9 kg/m
Understanding this CHS reference
A circular hollow section is a steel tube with a circular cross-section. Its outside diameter and wall thickness describe the basic geometry, while the listed sectional area and unit weight provide reference data for estimating material quantity and coordinating design information.
The values on this page are lookup data for the specific Celsius 355 CHS designation. Sectional area should not be treated as a complete indication of structural resistance: design checks may also depend on the loading, restraint, member length, connection arrangement, material requirements, and governing design rules.
How to use the listed properties
- Diameter: Use the stated outside diameter when coordinating clearances, interfaces, and drawing geometry.
- Thickness: Use the stated wall thickness when reviewing fabrication details, connection concepts, and section identification.
- Sectional area: Use this value as the cross-sectional area listed for the profile. It is not, by itself, a member capacity.
- Unit weight: Use the listed mass per metre for preliminary material takeoffs and weight coordination, subject to project verification.
Standard and CAD reference
The source identifies EN 10210-2 as the dimensional and sectional-property reference for this hollow-section entry, with EN 10210-1 covering technical delivery conditions. Confirm project specifications and the required standard documentation before final procurement or design approval.
The downloadable DWG can support drafting workflows. Check the drawing units, layer conventions, insertion point, and project drafting requirements before incorporating it into a production model.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section. It describes a hollow structural steel profile with a circular outside form.
What dimensions identify this profile?
This entry is identified by a 26.9 mm diameter and a 3.2 mm thickness. The source also lists its sectional area and unit weight.
What is EN 10210-2 used for here?
EN 10210-2 is the referenced standard for dimensions, tolerances, and sectional properties of the hollow-section product described on this page. Project requirements should be checked separately before using the data for procurement or final design.
Can the listed unit weight be used for a final quantity?
It can support preliminary quantity and weight coordination. Final quantities should account for the project specification, fabrication requirements, cut lengths, fittings, and any other applicable allowances.
Is the DWG suitable for construction drawings without checking?
No. Review the downloaded geometry, units, layers, and project drafting conventions before using the file in issued documentation.
