This reference page identifies the Celsius 355 circular hollow section (CHS) with the dimensions and section data listed in the source content. Use the values below when checking a drawing, comparing section schedules, or preparing preliminary detailing information.
The page also provides access to a DWG file for drafting workflows. Confirm the downloaded geometry and all design assumptions against the project specification and the applicable structural design requirements.
Celsius 355 CHS 60.3×3.6
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 : 3.6 mm
Sectional Area : 6.41 cm2
Unit Weight : 5 kg/m
How to read this CHS reference
A circular hollow section is a steel tube with a circular outside profile. The diameter describes the outside size, while the thickness describes the wall of the section. These dimensions are useful for identifying the section in drawings, fabrication documents, and section databases.
Sectional area and unit weight
The listed sectional area represents the steel area through a cut perpendicular to the member axis. It is used as a section-property input in engineering calculations and may also support material takeoff checks.
The unit weight is expressed per metre of member length. It provides a direct reference for estimating member mass over a known length, subject to normal fabrication, connection, coating, and project-specific allowances.
Standard reference and CAD use
The source identifies EN 10210-2 as the dimensional and sectional-property reference for this hot-finished hollow section. The standard reference should be read alongside the project material specification and the applicable design standard; a section designation alone does not replace member, connection, stability, or fabrication checks.
For drafting, the linked DWG can help users place the section in CAD details. Review units, layer conventions, insertion scale, and drawing orientation before incorporating the file into a project model.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section. It describes a hollow steel member with a circular cross-section.
What do 60.3×3.6 identify?
In this page title, the two dimensions identify the section diameter and wall thickness, respectively. The detailed source content confirms which dimension corresponds to each property.
What is the difference between sectional area and unit weight?
Sectional area describes the amount of steel in a cross-section. Unit weight describes the listed mass reference for each metre of the member. They are related but serve different purposes in design and estimating.
Is the DWG ready for every project?
The DWG is a drafting resource, not a substitute for project-specific design verification. Check its scale, units, geometry, and detailing requirements before use.
Does the section designation complete a structural design?
No. Member resistance, stability, connections, fabrication requirements, corrosion protection, and load effects must be checked by a suitably qualified engineer using the governing project requirements.
