This reference identifies the Celsius 355 circular hollow section (CHS) sized 48.3 x 2.6 mm. It brings the key source values together for engineers, detailers, estimators, and CAD users checking a section schedule or preparing a drawing.
Use the dimensional data below alongside the project specification and the applicable design checks. The supplied DWG file can support drafting workflows, while the tabulated properties remain the controlling reference for this page.
Celsius 355 CHS 48.3×2.6
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 : 2.6 mm
Sectional Area : 3.73 cm2
Unit Weight : 2.9 kg/m
Understanding the Celsius 355 CHS reference
A circular hollow section is a closed, round steel profile. In this entry, the section is identified by its outside diameter and wall thickness: 48.3 mm and 2.6 mm. Keeping these identifiers together helps prevent confusion when similar CHS sizes appear in a model, material list, or connection detail.

Standard reference
The source identifies EN 10210-2:2006-04 as the dimensional and sectional-property reference for hot-finished structural hollow sections. It supports EN 10210-1, which addresses technical delivery conditions. When using this entry for procurement or design documentation, check that the specified product, delivery condition, tolerances, and governing project standard align with the intended application.
Using the area and unit weight
The sectional area is a section-property value used in engineering calculations, while the unit weight expresses the listed mass per metre for quantity and estimating work. They should not be treated as interchangeable. For structural verification, combine the section data with the relevant material properties, loading, restraint, connection details, and applicable design method.
CAD and detailing workflow
The downloadable DWG provides a practical starting point for drawings and detailing. Confirm the drawing units, section orientation, connection clearances, and project layer conventions before incorporating it into a production document. Related SteelSTD resources on CHS terminology, steel section properties, and connection detailing can help place this profile in a wider drafting and design workflow.
