This reference covers a Celsius 355 rectangular hollow section (RHS) identified by the designation 60x40x6.3. The listing provides the section dimensions, corner radii, sectional area, unit weight, applicable standard reference, and a CAD download.
Use the dimensional information to confirm the section orientation and detailing requirements on drawings. The sectional area and unit weight are useful reference properties for material takeoffs and preliminary coordination, while design decisions require verification against the project specification and applicable engineering checks.

Width : 40 mm
Thickness : 6.3 mm
Outer Corner Radius : 9.4 mm
Inner Corner Radius : 6.3 mm
Sectional Area : 10.6 cm2
Unit Weight : 8.3 kg/m
How to read this RHS designation
RHS means rectangular hollow section. In this listing, the designation 60x40x6.3 identifies the nominal depth, width, and wall thickness in that order. The source content also reports the outside and inside corner radii, which are important when checking clearances, connections, fabrication details, and CAD geometry.
Section properties and material takeoff
The listed sectional area describes the material area through a cut section. It can support quantity calculations and coordination with structural analysis data. The unit weight expresses the listed mass per metre, making it useful when estimating member quantities, handling requirements, and overall steel tonnage. These values should be used together with the project documentation and the governing design method.
Standard and drawing reference
The entry refers to EN 10210-2:2006-04 for dimensional, tolerance, and sectional-property information for hot-finished structural hollow sections. The source also identifies the relationship with EN 10210-1, which addresses technical delivery conditions. Check the adopted project standard and procurement documents before treating the listing as a complete specification.
CAD and detailing workflow
The downloadable DWG can help users coordinate the section profile in drafting workflows. Before issuing drawings, verify the orientation, corner geometry, trimming, end preparation, connection clearances, and any fabrication allowances required by the project. A CAD profile is a drafting aid and does not replace design verification or manufacturer documentation.
Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section. It is a hollow steel profile with a rectangular outside form and rounded corners.
What does 60x40x6.3 identify?
It identifies the listed section by its depth, width, and wall thickness: 60 mm, 40 mm, and 6.3 mm respectively.
Which standard is referenced for this section?
The source refers to EN 10210-2:2006-04 and notes its connection with EN 10210-1 for technical delivery conditions.
Why are corner radii included?
Corner radii affect the actual profile geometry and can influence fit-up, clearances, connection detailing, and accurate CAD representation.
What is the purpose of the DWG file?
The DWG provides a drafting reference for the listed profile. It should be checked against project requirements and approved fabrication information before use in issued documentation.
