How to use the section data
The depth, width, and thickness identify the nominal rectangular hollow section. The outer and inner corner radii are important when preparing accurate drawings, checking clearances, or coordinating connections and fabrication details. They should not be treated as sharp-corner geometry in CAD unless the drawing or fabrication requirement specifically allows that simplification.
Sectional area is a cross-sectional property used in engineering calculations, while unit weight helps estimate material quantities and handling loads. Neither value alone establishes allowable resistance, buckling performance, connection capacity, or suitability for a particular structure; those checks require the applicable material, loading, restraint, and design information.
Standard and drafting context
The source identifies EN 10219-2 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections made from non-alloy and fine grain steels. It complements EN 10219-1, which addresses technical delivery conditions. See the site’s related structural hollow section, steel terminology, and EN 10219 references when additional specification or detailing context is needed.
A DWG file is available for use as a drafting reference. Confirm units, layer conventions, corner geometry, and project-specific detailing requirements before incorporating the file into production drawings.
Frequently asked questions
What does RHS 220x140x7 mean?
It identifies a rectangular hollow section with a nominal depth of 220 mm, width of 140 mm, and wall thickness of 7 mm.
Which standard is referenced for this section?
The source references EN 10219-2 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. It also notes the complementary role of EN 10219-1 for technical delivery conditions.
Why are the corner radii listed?
Rectangular hollow sections have formed corners rather than perfectly sharp corners. The listed outer and inner radii support more accurate CAD geometry, clearance checks, and connection or fabrication detailing.
What is the sectional area used for?
Sectional area is a cross-sectional property used in engineering calculations and quantity assessment. Design use requires confirmation of material and the governing project requirements.
Is the DWG file a design approval?
No. The DWG is a drafting reference. Designers should verify its geometry, units, and project compatibility before using it in issued documentation.
