This reference covers the Celsius 355 circular hollow section identified as CHS 48.3×5. Use the listed dimensions and section data when checking a drawing, comparing hollow-section references, or preparing a preliminary member schedule.
The page also provides context for EN 10210-2 and a DWG download link. For broader terminology, see related references on circular hollow sections, section properties, steel grades, and structural steel detailing.
Celsius 355 CHS 48.3×5
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 : 5 mm
Sectional Area : 6.8 cm2
Unit Weight : 5.3 kg/m
How to read this CHS reference
The designation 48.3×5 identifies the section by its circular outside diameter and wall thickness. The source data reports these values in millimetres, while sectional area is given in square centimetres and unit weight in kilograms per metre. Keeping the units associated with each property is important when transferring values into calculations, schedules, or CAD documentation.
Section properties and design checks
The listed sectional area and unit weight are reference properties for this specific section. They can support preliminary comparison and documentation, but they do not by themselves establish resistance, stability, connection capacity, or suitability for a particular structural application. Those checks depend on the complete design situation, material requirements, loading, restraint, fabrication, and applicable design rules.
Standard reference
The page cites EN 10210-2:2006-04 for dimensional tolerances, dimensions, and sectional properties for hot-finished structural hollow sections. The source also identifies its relationship with EN 10210-1, which addresses technical delivery conditions. Use the referenced standard and project requirements when tolerances, material delivery, inspection, or fabrication decisions matter.
Using the DWG file
The linked DWG is intended to support drafting and CAD coordination. Before using imported geometry for fabrication or structural documentation, check the drawing units, layer conventions, insertion scale, and project-specific detailing requirements. CAD geometry should be treated as a reference for the section rather than a substitute for the authoritative source data above.
Frequently asked questions
What does Celsius 355 CHS 48.3×5 mean?
It identifies a Celsius 355 circular hollow section with a nominal diameter of 48.3 mm and a wall thickness of 5 mm, as listed in the source content.
What information is provided for this CHS?
The reference provides the diameter, thickness, sectional area, unit weight, cited EN 10210-2 reference, and a DWG download link.
What is the difference between sectional area and unit weight?
Sectional area describes the cross-sectional material quantity used in section-property and design calculations. Unit weight describes the mass assigned per unit length for estimating member weight and preparing schedules.
Does the cited standard alone determine whether the section can be used?
No. A standard reference helps define the section and its product requirements, but application-specific design checks and project requirements still need to be verified by the responsible engineer.
Why download the DWG file?
The DWG can help with CAD layouts, drafting, and coordination. Confirm units and geometry after import, and use the listed source data when documenting the section.
