RHS 120x100x5 is a cold-formed welded rectangular hollow section with a nominal depth of 120 mm, width of 100 mm, and wall thickness of 5 mm. This page brings together the listed dimensions, corner radii, sectional area, unit weight, applicable standard reference, and a downloadable DWG file.
Use this entry alongside the site’s steel terminology, section properties, and CAD/DWG reference resources when checking drawings, schedules, or preliminary section selections. The tabulated values on this page remain the controlling local reference for this section.
RHS 120x100x5
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 : 120 mm
Width : 100 mm
Thickness : 5 mm
Outer Corner Radius : 10 mm
Inner Corner Radius : 5 mm
Sectional Area : 20.36 cm2
Unit Weight : 16 kg/m
Understanding the RHS designation
RHS means rectangular hollow section. In the designation 120x100x5, the first two dimensions identify the outside depth and width, while the final dimension identifies the wall thickness. The source data lists these as a depth of 120 mm, a width of 100 mm, and a thickness of 5 mm.
Corner radii and section properties
The listed outer corner radius is 10 mm and the listed inner corner radius is 5 mm. Corner geometry is part of the section definition and can matter when a detail, connection, fit-up condition, or fabrication drawing depends on the outside profile.
The source also reports a sectional area of 20.36 cm2 and a unit weight of 16 kg/m. These values are useful for reading section schedules and estimating material quantities, but design checks should use the applicable project requirements and verified section data.
Applicable EN 10219 references
The entry refers to EN 10219-2 for tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections made from non-alloy and fine grain steels. It also identifies EN 10219-1 as the related reference for technical delivery conditions. These references should be read together with the project specification and procurement documentation where applicable.
DWG reference file
The downloadable DWG associated with this entry can support drafting and model coordination. Confirm units, layer conventions, insertion settings, and the intended use of the drawing before incorporating it into a production document. A CAD outline is a reference resource and does not replace project-specific detailing or engineering verification.
Frequently asked questions
What does RHS 120x100x5 mean?
It identifies a rectangular hollow section with a listed outside depth of 120 mm, outside width of 100 mm, and wall thickness of 5 mm.
What are the listed corner radii?
The source lists an outer corner radius of 10 mm and an inner corner radius of 5 mm.
What sectional area and unit weight are listed?
The listed sectional area is 20.36 cm2, and the listed unit weight is 16 kg/m.
What does EN 10219-2 refer to here?
In this entry, EN 10219-2 is identified as the reference for tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections. EN 10219-1 is identified for technical delivery conditions.
Is the DWG file a design approval document?
No. The DWG is provided as a drafting and reference resource. Its geometry and use should be checked against the project requirements, and engineering verification remains necessary for design decisions.
