This page provides a quick reference for the Celsius 355 circular hollow section identified as 60.3×3.2. Use the source values below when checking section dimensions, mass, or sectional area in design and drafting workflows.
For broader context, see related guidance on circular hollow sections, steel section properties, and structural steel terminology. These topics help explain how hollow-section geometry is represented and how published properties support engineering checks.
Celsius 355 CHS 60.3×3.2
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 : 3.2 mm
Sectional Area : 5.74 cm2
Unit Weight : 4.5 kg/m
How to read this CHS reference
The designation combines the nominal outside diameter with the wall thickness. The source data identifies the diameter and thickness separately, followed by the calculated sectional area and unit weight. Keep the units attached to each value because area and mass are used differently in design, estimating, and fabrication documentation.
Standard reference
The listed reference is EN 10210-2:2006-04. In this context, the standard is used for dimensional tolerances and sectional-property information for hot-finished structural hollow sections. The related delivery requirements are associated with EN 10210-1, as noted in the source content.
Using the section data
The sectional area can support member-resistance and stress calculations when used with the applicable design method and material information. The unit weight is useful for preliminary material takeoffs, handling estimates, and drawing notes. Neither value should be treated as a complete design check; connection behavior, buckling, loading, restraint, fabrication, and applicable project requirements must be evaluated separately.
The attached DWG provides a CAD reference for drafting. Confirm the drawing unit settings, layer conventions, and project-specific tolerances before incorporating geometry into production documentation. Related internal resources may include CHS connection detailing, CAD and DWG references, and structural steel design terminology.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section. It describes a steel section with a circular outside profile and a hollow interior.
What does 60.3×3.2 identify?
In this reference, the designation identifies the listed diameter and wall thickness. The source content gives the corresponding units and section properties.
What is EN 10210-2 used for here?
It is the cited reference for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. The source also notes its relationship to EN 10210-1 for technical delivery conditions.
What is the difference between sectional area and unit weight?
Sectional area describes the material area in a cut through the section. Unit weight describes the mass associated with a unit length. They serve different purposes in structural calculations and material estimating.
Can the DWG be used directly for fabrication?
The DWG is a drafting reference. Review its units, project standards, fabrication requirements, and engineering details before using it in issued documentation.
