The page also points to the applicable EN 10210-2 reference and provides a DWG download for drafting workflows. For related terminology, see the site’s resources on structural hollow sections, section properties, and steel connections.
Celsius 355 CHS 48.3×3.6
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 : 48.3 mm
Thickness : 3.6 mm
Sectional Area : 5.06 cm2
Unit Weight : 4 kg/m
How to read the CHS designation
CHS means circular hollow section. In this designation, 48.3 identifies the diameter and 3.6 identifies the wall thickness, both in millimetres. The source data lists a sectional area of 5.06 cm2 and a unit weight of 4 kg/m.
Standard reference
The source refers to EN 10210-2:2006-04, which addresses dimensions, tolerances, and sectional properties for hot-finished structural hollow sections. It is used alongside EN 10210-1, which covers technical delivery conditions. Consult the project specification and the applicable standard documents before using the section in design or fabrication.
Using the section data
- Diameter and thickness: useful for checking space, detailing, and drawing annotations.
- Sectional area: a listed geometric property for reference and engineering calculations.
- Unit weight: supports estimating linear steel mass for schedules and takeoffs.
- DWG resource: the downloadable file can support drafting and CAD coordination; verify the drawing against the authoritative project information before issue.
