RHS 160x90x5 is a cold formed welded rectangular hollow section reference for engineers, detailers, fabricators, and CAD users working with structural steel documentation. This page brings together the published profile dimensions, corner radii, sectional area, and unit weight while identifying the relevant European standard reference.
Use the existing data below as the controlling local reference for this section. For design or fabrication decisions, confirm the required steel grade, delivery condition, connection details, corrosion protection, and project-specific requirements with the applicable project documents and a qualified engineer.
RHS 160x90x5
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.

Depth : 160 mm
Width : 90 mm
Thickness : 5 mm
Outer Corner Radius : 10 mm
Inner Corner Radius : 5 mm
Sectional Area : 23.36 cm2
Unit Weight : 18.3 kg/m
How to read the RHS 160x90x5 reference
The designation describes a rectangular hollow section by its overall depth, overall width, and wall thickness. The source content lists these dimensions in millimetres and also identifies the outside and inside corner radii. Corner geometry is important when preparing accurate drawings, checking clearances, or coordinating connections and fittings around the tube profile.
The listed sectional area is a geometric property of the steel cross-section. The listed unit weight provides a mass reference for quantity takeoffs, handling discussions, and preliminary material estimates. These values should be read together with the project’s material specification and fabrication requirements rather than treated as a substitute for a complete design check.
Standard and documentation context
The page refers to EN 10219-2 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections made from non-alloy and fine grain steels. The source also distinguishes the related technical delivery requirements covered by EN 10219-1. Always confirm the applicable standard edition and material documentation for the project.
Drafting and section selection considerations
The accompanying DWG resource can support drawing coordination and CAD-based detailing. Before using a downloaded profile in a model or fabrication drawing, check the section orientation, corner representation, units, layer standards, and any project-specific drafting conventions.
When comparing this profile with other rectangular hollow sections, review more than the outside dimensions. Wall thickness, corner geometry, sectional area, unit weight, required material grade, connection method, and the governing design checks all affect whether a section is appropriate for a particular application.
Frequently asked questions
What does RHS 160x90x5 mean?
It identifies a rectangular hollow section with the published overall depth, overall width, and wall thickness shown in the source data. The exact listed dimensions and associated properties remain the controlling reference for this page.
Which standard is referenced for this section?
The source refers to EN 10219-2 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. It also notes that EN 10219-1 covers technical delivery conditions.
Why are the corner radii included?
Rectangular hollow sections have formed corners rather than perfectly sharp external and internal intersections. The stated radii help users interpret the actual profile shape for CAD modeling, detailing, fit-up, and clearance coordination.
What is the sectional area used for?
Sectional area describes the amount of steel in the cross-section. It can support material quantity calculations and engineering checks, but the appropriate design use depends on the governing code, steel grade, loading, stability, and connection details.
Is a DWG file available for this profile?
The source includes a DWG download resource for RHS 160x90x5. Review the file and confirm units, geometry, and drafting conventions before incorporating it into project documentation.
