RHS 200x120x10 is a cold-formed welded rectangular hollow section reference for structural steel detailing and design review. This page brings together the published dimensions, corner geometry, sectional area, unit weight, applicable standard context, and a CAD drawing resource.
Use the dimensional data as a section-identification reference, then confirm the required steel grade, loading assumptions, connection details, fabrication requirements, and design checks before specifying the section for a project.
RHS 200x120x10
Cold Formed Welded Rectangular Steel Tubes
refer to : EN 10219-2
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.

Depth : 200 mm
Width : 120 mm
Thickness : 10 mm
Outer Corner Radius : 25 mm
Inner Corner Radius : 15 mm
Sectional Area : 56.57 cm2
Unit Weight : 44.4 kg/m
Understanding the RHS designation
The RHS designation identifies a rectangular hollow section by its outside depth, outside width, and wall thickness. The listed dimensions describe the overall rectangular envelope and the material thickness, while the outside and inside corner radii describe the curved transitions between the flat faces.
What the reference properties mean
The sectional area represents the amount of steel in the cross-section and is used in calculations such as axial resistance and mass estimation. The unit weight supports quantity takeoffs, handling planning, and drawing coordination. These properties should be read together with the section dimensions and the assumptions used by the applicable design method.
Standard and fabrication context
The source identifies EN 10219-2 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. It also distinguishes the related technical delivery requirements covered by EN 10219-1. Standard references do not replace project-specific checks for material certification, welds, cutting, forming, surface condition, or connection detailing.
Using the CAD resource
The linked DWG resource can support drafting and layout work involving this rectangular tube profile. Before issuing drawings, check the drawing units, layer conventions, corner geometry, material notes, and connection interfaces against the project documentation and the authoritative section data on this page.
RHS 200x120x10 FAQ
What does RHS mean?
RHS means rectangular hollow section. It is a closed structural steel profile with flat rectangular faces and rounded corners.
Which standard is identified for this section?
The source identifies EN 10219-2 for dimensions, tolerances, and sectional properties, with EN 10219-1 covering technical delivery conditions.
Why are the corner radii listed?
Corner radii describe the formed geometry of the tube and affect the actual section shape, drafting representation, fabrication interpretation, and some engineering calculations.
Can the CAD drawing be used directly for fabrication?
The DWG is a drafting reference. Confirm units, material requirements, weld details, fabrication tolerances, and project-specific revisions before using it for fabrication documentation.
Does the listed unit weight replace a design check?
No. Unit weight helps with estimating and coordination, but structural design also requires verification of loads, restraints, connections, material properties, and the governing design requirements.
