RHS 150x75x7 is a cold formed welded rectangular hollow section reference for steel detailing, specification review, and preliminary section identification. This page presents the reported dimensions and section data without replacing the authoritative source values.
Use the reference alongside your project specification, material documentation, and applicable design checks. The downloadable DWG can support drafting workflows, but the drawing should be reviewed against the project’s required tolerances, connection details, and fabrication requirements.
RHS 150x75x7
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.

How to read the RHS 150x75x7 reference
The designation 150x75x7 identifies the rectangular section by its listed depth, width, and wall thickness. The reference also gives the outer and inner corner radii, which describe the curved transitions between the flat faces of the hollow section.
Key section data
- Depth and width: These describe the principal outside dimensions used to orient the rectangular profile in drawings and schedules.
- Thickness: This is the listed wall thickness of the tube and should be checked against the project specification and fabrication documentation.
- Corner radii: The outer and inner radii affect the profile geometry, clearances, detailing, and how the section is represented in CAD.
- Sectional area: This is a geometric property used with other section information in engineering calculations. It should not be treated as a complete design verification by itself.
- Unit weight: The listed mass per unit length is useful for estimating steel quantities and coordinating member schedules, subject to confirmation from the selected product and specification.
Standard and drafting context
The source refers to EN 10219-2 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. It also identifies the relationship with EN 10219-1, which addresses technical delivery conditions. Always confirm the required standard designation and material requirements before issuing fabrication or procurement information.
For related reference work, connect this section to internal guidance on rectangular hollow sections, steel section properties, steel tolerances, CAD and DWG detailing, and hollow-section connections. These topics help readers move from profile identification to coordinated design and drafting review.
RHS 150x75x7 FAQ
What does RHS 150x75x7 mean?
It is the designation for a rectangular hollow section with the listed depth, width, and wall thickness. The page provides the corresponding corner radii, sectional area, and unit weight.
Which standard is referenced for this section?
The reference identifies EN 10219-2 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. EN 10219-1 is identified for technical delivery conditions.
Why are the corner radii important?
Corner radii define the curved portions of the tube profile. They can affect clearances, connection detailing, section representation in CAD, and coordination with adjoining components.
Can the DWG be used directly for fabrication?
The DWG is a drafting reference and should be checked against the project specification, approved manufacturer information, required tolerances, and fabrication details before use in issued documents.
Does the listed unit weight replace a design check?
No. Unit weight supports quantity and schedule coordination, while structural adequacy requires the applicable design information, load effects, connection checks, and engineering verification.
