RHS 60x40x4 is a cold-formed welded rectangular hollow section used as a compact steel profile reference for detailing, drafting, and preliminary section comparison. This page brings together the profile dimensions, corner radii, sectional area, unit weight, and the applicable European standard reference in one place.
Use the dimensional information below alongside the section properties required for your design or detailing workflow. The downloadable DWG resource can support CAD work, while the related steel terminology and section properties references provide useful background when comparing hollow sections.

Understanding the RHS 60x40x4 designation
RHS means rectangular hollow section. In the designation 60x40x4, the first two dimensions identify the outside depth and width, while the final dimension identifies the wall thickness. The source data lists the profile depth as 60 mm, width as 40 mm, and thickness as 4 mm.
Corner radii and section geometry
Unlike a flat-sided plate arrangement, a rectangular hollow section has rounded outside and inside corners. The listed outer and inner corner radii are important when preparing accurate CAD details, checking clearances, or comparing the profile with another hollow section. They also help distinguish the nominal outside dimensions from the actual geometric boundaries of the section.
Sectional area and unit weight
The listed sectional area describes the steel material contained in the cross-section, while the unit weight expresses the profile’s mass per unit length. These values are useful for quantity takeoffs, member comparisons, and coordination with connection or fabrication details. They should not be treated as a substitute for the complete design checks required for a specific application.
Standard reference
The source refers to EN 10219-2, which addresses tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections made from non-alloy and fine grain steels. It complements EN 10219-1, which covers technical delivery conditions. Confirm the required material documentation and project requirements before using a section in fabrication or structural design.
Using the DWG reference
The associated DWG download is intended to support drafting and model coordination. Check the drawing units, layer conventions, and project-specific detailing requirements before incorporating the profile into production documents. For broader CAD support, see the site’s CAD/DWG reference resources.
Frequently asked questions
What does RHS 60x40x4 mean?
It identifies a rectangular hollow section with a listed outside depth of 60 mm, outside width of 40 mm, and wall thickness of 4 mm.
Which standard is referenced for this profile?
The source references EN 10219-2 for tolerances, dimensions, and sectional properties, alongside EN 10219-1 for technical delivery conditions.
Why are the corner radii listed?
Corner radii describe the rounded transitions at the outside and inside corners of the tube. They are useful for accurate CAD geometry, clearances, and fabrication detailing.
What is the DWG file used for?
The DWG file provides a CAD reference for drafting and coordination. Review its geometry and project settings before using it in design or fabrication documentation.
Can the listed values be used for structural design?
The listed values are reference data for this profile. A qualified engineer must verify the complete design, including material requirements, loads, stability, connections, fabrication, and applicable project rules.
