This reference page covers the Hybox 355 rectangular hollow section identified as RHS 200x100x10. Use the source data below to review its principal dimensions, corner geometry, sectional area, unit weight, applicable standard reference, and available CAD file.
For practical steel detailing, compare this entry with other rectangular hollow sections and review the distinction between nominal section dimensions, corner radii, and calculated section properties before using the information in drawings or design checks.
Hybox 355 RHS 200x100x10
Hybox 355 Rectangular Hollow Sections
refer to : EN 10219-2:2006-04
the European standard that specifies tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections made of non-alloy and fine grain steels. It complements EN 10219-1, which covers technical delivery conditions.
Dimension : 200x100x10
Depth : 200 mm
Width : 100 mm
Thickness : 10 mm
Outer Corner Radius : 25 mm
Inner Corner Radius : 15 mm
Sectional Area : 52.6 cm2
Unit Weight : 41.3 kg/m
How to read the RHS reference
The designation 200x100x10 identifies the listed outside depth, outside width, and wall thickness. The page also reports separate outer and inner corner radii, which describe the rounded transitions between the flat faces of the hollow section.
The listed sectional area and unit weight are reference properties for this specific section. They can support quantity checks, section comparisons, and drafting coordination, but design use still requires confirmation of the governing project requirements, material specification, load effects, connection details, and applicable design rules.
Standard reference and documentation
The source refers to EN 10219-2:2006-04, which addresses dimensions, tolerances, and sectional properties for cold-formed welded structural hollow sections. The source also notes that EN 10219-2 complements EN 10219-1, which covers technical delivery conditions.
The downloadable DWG is useful for drawing preparation and detailing workflows. Check the drawing file against the published section dimensions before issuing fabrication or construction documents, particularly where corner geometry affects fit-up, connection detailing, or clearances.

Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section. It describes a hollow steel section with a rectangular outside profile and closed walls.
What do the three numbers in 200x100x10 represent?
For this listing, the designation identifies the reported depth, width, and wall thickness. The source provides those dimensions separately in millimetres.
Why are both outer and inner corner radii listed?
The two radii describe the rounded outer and inner transitions at the section corners. They help distinguish the actual section geometry from a simple sharp-corner rectangle.
Which standard is referenced for this section?
The source references EN 10219-2:2006-04 and identifies it as the standard covering dimensions, tolerances, and sectional properties for the relevant cold-formed welded structural hollow sections. It also notes the relationship with EN 10219-1.
Can the listed unit weight be used for design?
The unit weight is a reference property for estimating steel quantities and checking models. Engineering design should also verify the project specification, loads, connections, fabrication requirements, and governing design rules.
What is the DWG file used for?
The DWG supports CAD and detailing workflows. Confirm its units, scale, geometry, and consistency with the published reference before using it in project documentation.
