This RHS 200x150x10 reference provides the published dimensions and basic section data for a cold formed welded rectangular steel tube. Use it as a practical starting point when reviewing structural steel shapes, preparing drawings, or comparing hollow section references.
The page also identifies the relevant EN 10219-2 context and provides a downloadable DWG resource for drafting workflows. For related guidance, see our references on section properties, steel terminology, and structural steel connections.
RHS 200x150x10
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 : 200x150x10
Depth : 200 mm
Width : 150 mm
Thickness : 10 mm
Outer Corner Radius : 25 mm
Inner Corner Radius : 15 mm
Sectional Area : 62.57 cm2
Unit Weight : 49.1 kg/m
How to read this RHS reference
The dimension designation identifies the rectangular hollow section by its overall depth, overall width, and wall thickness. The listed depth, width, and thickness should be read together with the corner-radius information because the section is not composed only of flat plates with sharp corners.
Corner radii and section geometry
The outer and inner corner radii describe the formed transitions between the flat faces of the tube. These values are important when interpreting the section outline, checking detailing clearances, or comparing CAD geometry with a published steel-shape reference.
Sectional area and unit weight
Sectional area is a geometric property used as an input to engineering calculations and section-property reviews. Unit weight expresses the listed mass per unit length, which is useful for estimating material quantities and checking drawing or schedule information. Neither value, by itself, confirms capacity or design suitability.
EN 10219-2 context
The source identifies EN 10219-2 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. It also distinguishes that reference from EN 10219-1, which covers technical delivery conditions. Confirm the applicable material, fabrication, tolerances, and design requirements against the project specification and governing design documents.
CAD and detailing resource
The downloadable DWG can support drafting and coordination tasks involving this rectangular hollow section. Review the file geometry against the published reference before using it in fabrication documentation, connection detailing, or a design model.
Frequently asked questions
What does RHS 200x150x10 mean?
It identifies a rectangular hollow section with the published overall depth, overall width, and wall thickness shown on this page. The reference also lists the associated corner radii.
What standard is referenced for this section?
The page refers to EN 10219-2 for the relevant dimensions, tolerances, and sectional-property context, while EN 10219-1 is identified for technical delivery conditions.
What is the difference between sectional area and unit weight?
Sectional area describes the cross-sectional geometry. Unit weight describes the mass associated with a unit length of the section. They serve different purposes and should not be treated as interchangeable design values.
Can the DWG be used directly for fabrication?
The DWG is a drafting reference. Check its geometry, project requirements, connection details, and fabrication information before issuing drawings or using it for manufacture.
Does this reference establish structural capacity?
No. Capacity depends on the material, loading, restraint, connection, limit state, design standard, and other project-specific conditions. Engineering verification is required.
