Celsius 355 CHS 76.1×5.6
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 : 76.1 mm
Thickness : 5.6 mm
Sectional Area : 12.4 cm2
Unit Weight : 9.7 kg/m
How to read the CHS designation
CHS means circular hollow section. In the designation 76.1×5.6, the first value identifies the outside diameter and the second identifies the wall thickness. These dimensions are the primary profile identifiers when selecting a section from a steel-shape library or CAD model.
Understanding the listed section data
The sectional area describes the cross-sectional steel area of the member. Engineers may use this property with other section data when checking axial resistance, self-weight, or related design effects; it should not be treated as a complete design result by itself.
The unit weight expresses the mass assigned to each metre of the section. This value is useful for estimating member dead load, material quantities, and shipping or fabrication requirements. Project calculations should use the applicable design basis and verified material information.
Standard and CAD reference
The source identifies EN 10210-2:2006-04 as the dimensional and sectional-property reference for this profile family, with the related technical delivery requirements identified through EN 10210-1. Refer to the project specification and controlling standard documents when tolerances, material delivery, fabrication, or compliance decisions are required.
The downloadable DWG can support drafting and coordination. Check the drawing units, insertion scale, layer conventions, and project detailing requirements before incorporating it into production documentation.
Frequently asked questions
What does Celsius 355 CHS 76.1×5.6 mean?
It identifies a Celsius 355 circular hollow section with a 76.1 mm diameter and a 5.6 mm wall thickness.
What is the sectional area of this CHS?
The listed sectional area is 12.4 cm2. Use it together with the relevant design checks and other required section properties rather than as a stand-alone capacity value.
What is the unit weight?
The listed unit weight is 9.7 kg/m. It can support preliminary material quantity and self-weight calculations, subject to project verification.
Which standard is referenced?
The source references EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties, and identifies EN 10210-1 for technical delivery conditions.
Is a CAD file available?
Yes. A DWG download is provided for the Celsius 355 CHS 76.1×5.6 profile. Review scale and drafting conventions before using it in a project drawing.
