This page provides a focused reference for the Celsius 355 circular hollow section identified as CHS 114.3×6.3. The listed dimensions and section data are presented alongside the cited European standard and a downloadable DWG resource for drafting workflows.
Use this entry when checking a hollow-section designation, reviewing basic member data, or locating a CAD reference. For design work, confirm the applicable material specification, loading, connection details, corrosion allowance, and verification requirements before selecting a section.
Celsius 355 CHS 114.3×6.3
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 : 114.3 mm
Thickness : 6.3 mm
Sectional Area : 21.4 cm2
Unit Weight : 16.8 kg/m
How to read the CHS designation
CHS means circular hollow section. In the designation 114.3×6.3, the first value identifies the listed diameter and the second identifies the listed wall thickness. These values describe the section geometry; they do not by themselves establish resistance, serviceability performance, or connection capacity.
Reference data for this section
- Diameter: 114.3 mm
- Thickness: 6.3 mm
- Sectional area: 21.4 cm2
- Unit weight: 16.8 kg/m
The sectional area is useful when reviewing material quantity and member-property references. The unit weight supports estimating and detailing checks, but it should be used as listed rather than treated as a substitute for project-specific fabrication or coating allowances.
Standard and drafting context
The source references EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. It also identifies the relationship with EN 10210-1, which addresses technical delivery conditions. Consult the project-specified standard, material documentation, and governing design requirements before relying on any listed property.
The downloadable DWG can support layout, detailing, and CAD coordination. Check units, layer conventions, insertion scale, and the drawing against the authoritative project data before issuing fabrication or construction information.
