RHS 140x70x7 is a cold-formed welded rectangular hollow section listed with dimensional, geometric, and mass information for steel reference and drafting work. The source data identifies the section under EN 10219-2 and provides its principal dimensions, corner radii, sectional area, and unit weight.
Use the technical listing below as the controlling local reference. For design, fabrication, and procurement, confirm the required steel grade, delivery condition, tolerances, connection details, and project requirements with the applicable documentation and a qualified engineer.

Unit Weight : 20.2 kg/m
How to read the RHS 140x70x7 reference
RHS means rectangular hollow section. The designation communicates the section’s nominal outside depth, outside width, and wall thickness in the order shown in the title. The detailed listing separates these dimensions so they can be checked independently when preparing drawings, schedules, or section-property references.
Corner radii and section geometry
The outer and inner corner radii describe the rounded transitions between the flat faces of the tube. These radii matter when checking the actual formed profile, coordinating connections, or comparing a CAD outline with a published section reference. They should not be treated as sharp-corner dimensions.
Sectional area and unit weight
Sectional area is a geometric property used in engineering calculations and section comparisons. Unit weight expresses the listed mass per unit length and is useful for estimating member mass, handling requirements, and material quantities. Neither value alone establishes the strength or suitability of a member for a particular application.
Standard and CAD reference
The source identifies EN 10219-2 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections, while EN 10219-1 addresses technical delivery conditions. Keep those roles distinct when reviewing specifications. The linked DWG can support drafting and coordination, but the drawing should be checked against the project’s required tolerances, fabrication method, and connection details before use.
Related reference topics include rectangular hollow sections, steel section properties, EN 10219, steel connection detailing, and structural steel CAD blocks.
RHS 140x70x7 FAQ
What does RHS 140x70x7 mean?
It identifies a rectangular hollow section by its nominal outside depth, outside width, and wall thickness. The page’s source block gives the corresponding dimensions in millimeters.
What type of section is RHS 140x70x7?
The source describes it as a cold-formed welded rectangular steel tube. Its hollow rectangular geometry includes defined outer and inner corner radii.
What is EN 10219-2 used for?
EN 10219-2 is referenced for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. Technical delivery conditions are addressed separately under EN 10219-1, as noted in the source.
What is the difference between sectional area and unit weight?
Sectional area describes the steel material contained in the cross-section. Unit weight describes the listed mass associated with a unit length of the section. Both are reference values, but they serve different purposes in calculations and quantity estimates.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference and should be reviewed before fabrication. Confirm the project dimensions, tolerances, material requirements, corner geometry, connection details, and fabrication instructions against the governing documents.
