The RHS 100x50x5 is a cold-formed welded rectangular hollow section (RHS) with a nominal depth of 100 mm, width of 50 mm, and wall thickness of 5 mm. This page provides the section dimensions, corner radii, sectional area, unit weight, applicable reference, and a downloadable DWG resource.
Use the listed values as a reference when reviewing structural hollow sections, preparing drawings, or coordinating steel detailing. Any use in a structural design should be checked against the governing project requirements, material specification, loading, connection details, and applicable design rules.
RHS 100x50x5
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.
Dimension : 100x50x5
Depth : 100 mm
Width : 50 mm
Thickness : 5 mm
Outer Corner Radius : 10 mm
Inner Corner Radius : 5 mm
Sectional Area : 13.36 cm2
Unit Weight : 10.5 kg/m
How to read the RHS 100x50x5 designation
In the designation RHS 100x50x5, the first two dimensions identify the rectangular section’s depth and width, while the final dimension identifies the nominal wall thickness. The source data lists the depth as 100 mm, the width as 50 mm, and the thickness as 5 mm.
Because the section is rectangular, its orientation can matter in drawings and design checks. Confirm which dimension is being used as the depth when reviewing section properties, member orientation, connection details, or CAD models.
Corner radii and section geometry
The listed outer corner radius is 10 mm and the listed inner corner radius is 5 mm. These radii describe the rounded transitions at the section corners and should be considered when creating accurate fabrication drawings, checking clearances, or modeling the profile in CAD. They also explain why the section should not be treated as a sharp-cornered rectangle for detailed geometric work.
Sectional area and unit weight
The source lists a sectional area of 13.36 cm2 and a unit weight of 10.5 kg/m. Sectional area is a key section-property input for engineering checks, while unit weight supports material quantity estimates and preliminary dead-load calculations. These values should be used with the applicable material grade, design standard, tolerances, and project assumptions rather than as a substitute for a complete member design.
Standard reference and CAD resource
This profile refers to EN 10219-2, which addresses dimensions, tolerances, and sectional properties for cold-formed welded structural hollow sections. The source also identifies EN 10219-1 as covering technical delivery conditions. For drafting workflows, the available RHS 100x50x5 DWG can help with profile representation, but the downloaded geometry should be checked against the project specification before fabrication or construction use.
Related reference topics include rectangular hollow section properties, steel grades, connection and detailing concepts, and structural steel CAD resources.
