RHS 50x20x2
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 : 50 mm
Width : 20 mm
Thickness : 2 mm
Outer Corner Radius : 4 mm
Inner Corner Radius : 2 mm
Sectional Area : 2.54 cm2
Unit Weight : 2 kg/m
How to read this RHS reference
The designation RHS 50x20x2 describes a rectangular hollow section with a listed depth, width, and wall thickness. The section is identified as cold formed and welded, so the manufacturing description is part of the reference alongside the dimensional data.
Corner radii and section geometry
The listed outer and inner corner radii describe the rounded transitions between the flat faces of the tube. These details matter when interpreting the section outline, preparing fabrication drawings, or coordinating the profile with connected parts. They should not be replaced by sharp-corner geometry in CAD unless the design or fabrication process specifically requires that simplification.
Sectional area and unit weight
The sectional area is useful for reviewing the steel cross-section, while the listed unit weight supports material takeoffs and preliminary estimating. These values are reference data for this profile; they do not by themselves establish resistance, stability, allowable loading, or connection capacity.
Standard reference and CAD workflow
The source cites EN 10219-2 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections, and distinguishes it from EN 10219-1, which addresses technical delivery conditions. For drafting workflows, the linked DWG can help users place the profile in CAD while retaining the source dimensions for checking.
Related reference topics include rectangular hollow sections, steel section properties, structural steel terminology, and connection detailing.
Frequently asked questions
What does RHS 50x20x2 mean?
It is the designation for a rectangular hollow steel section with the depth, width, and wall thickness listed in the source entry.
What type of steel product is referenced?
The entry describes a cold-formed welded rectangular steel tube and refers to EN 10219-2 for relevant dimensional, tolerance, and sectional-property information.
What are the corner radii used for?
The outer and inner corner radii define the rounded corner geometry of the tube. They are useful when checking the profile in drawings or coordinating it with other components.
Can the DWG be used directly for structural design?
The DWG is a drafting reference. Structural design still requires verification of the governing material, loads, limit states, connections, fabrication requirements, and project standard.
