SHS 90x90x5 is a cold-formed welded square hollow section with equal outside depth and width and a 5 mm wall thickness. This reference page brings together the published dimensions, corner radii, sectional area, unit weight, and related DWG resource for drafting and engineering reference work.
Use the dimensional data below when checking a drawing, comparing square hollow sections, or preparing a preliminary section schedule. Final member selection still depends on the steel grade, applied actions, restraint, connection details, fabrication requirements, and the governing design rules.
SHS 90x90x5
Cold Formed Welded Square 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.
Dimension : 90x90x5
Depth : 90 mm
Width : 90 mm
Thickness : 5 mm
Outer Corner Radius : 10 mm
Inner Corner Radius : 5 mm
Sectional Area : 16.36 cm2
Unit Weight : 12.8 kg/m
How to read the SHS designation
In SHS 90x90x5, the first two dimensions describe the outside depth and width of the square section. Because they are equal, the profile has a square external shape. The final dimension identifies the nominal wall thickness.
The listed outer and inner corner radii describe the rounded transitions between the flat faces. These radii are important when interpreting CAD geometry, checking clearances, or comparing a simplified schematic representation with the actual hollow-section profile.
Section data and standard context
The source data reports a sectional area of 16.36 cm2 and a unit weight of 12.8 kg/m. Sectional area is commonly used in section-property and member-reference work, while unit weight supports material takeoff and approximate mass calculations. Use the published values as the controlling reference for this page rather than estimating them from nominal dimensions.
This profile is identified as a cold-formed welded square steel tube and refers to EN 10219-2 for dimensional, tolerance, and sectional-property information. The source also distinguishes the related technical delivery requirements covered by EN 10219-1. For procurement or design documentation, verify the applicable material grade, delivery condition, tolerances, and project specification separately.
Drafting and design workflow
- Use the nominal outside dimensions and wall thickness when identifying the section in drawings and schedules.
- Account for the stated corner radii when developing detailed CAD geometry or checking adjacent clearances.
- Use the reported sectional area and unit weight for reference calculations, while obtaining any additional section properties required by the design check.
- Download the associated DWG when a reusable square-tube profile is needed for layout or detailing.
For broader reference work, this page can be used alongside SteelSTD resources covering structural hollow sections, steel section properties, connection and detailing concepts, and CAD/DWG section profiles.
Frequently asked questions
What does SHS 90x90x5 mean?
It identifies a square hollow section with a 90 mm outside depth, a 90 mm outside width, and a nominal 5 mm wall thickness.
What type of steel section is this?
It is described as a cold-formed welded square steel tube. The source refers to EN 10219-2 for dimensional, tolerance, and sectional-property information.
What are the reported area and unit weight?
The published sectional area is 16.36 cm2, and the published unit weight is 12.8 kg/m. These values should be taken from the reference data when preparing schedules or preliminary calculations.
Why do the corner radii matter?
Corner radii define the rounded transitions between the flat faces of the tube. They can affect CAD representation, fit-up, detailing clearances, and comparisons between nominal dimensions and manufactured geometry.
Is the SHS 90x90x5 automatically suitable for a structural application?
No. Suitability depends on the material grade, loading, span, restraint, buckling conditions, connection design, fabrication, corrosion considerations, and applicable design requirements. A qualified engineer should verify the complete application.
Is a CAD file available?
Yes. The source includes a DWG download associated with the SHS 90x90x5 profile. Check the downloaded geometry against the published dimensions before using it for project documentation.
