This reference identifies the Celsius 355 circular hollow section (CHS) with a 60.3 mm diameter and 2.6 mm thickness. It brings the key dimensional and mass information together for structural steel specification, drafting, and preliminary section comparison.
Use the listed values as the controlling local reference for this page. For design, fabrication, and connection work, confirm the applicable project requirements, material documentation, and engineering checks before relying on the section.
Celsius 355 CHS 60.3×2.6
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 : 60.3 mm
Thickness : 2.6 mm
Sectional Area : 4.71 cm2
Unit Weight : 3.7 kg/m
How to read this CHS reference
A circular hollow section is a round structural steel profile with a hollow interior. Its diameter and wall thickness describe the basic geometry, while sectional area and unit weight help with material takeoff, member comparison, and drawing coordination.
Sectional area and unit weight
The sectional area represents the steel area through a transverse cut of the member. The listed unit weight expresses the mass associated with each metre of section. These properties are useful for estimating steel quantities and reviewing model or schedule data, but they do not replace the checks required for a particular member, connection, or load case.
Standard reference
This entry refers to EN 10210-2:2006-04, which addresses dimensions, tolerances, and sectional properties for hot-finished structural hollow sections. It is used with the related technical delivery requirements identified in the source entry. When preparing a specification, coordinate this reference with the project material standard and the governing design basis.
Drafting and CAD use
The downloadable DWG can support layout and detailing workflows. Before issuing drawings, check the imported geometry, units, layer conventions, and any project-specific drafting requirements. Useful related references include circular hollow section terminology, structural steel section properties, hollow-section connections, and steel member schedules.
