How to read this SHS reference
SHS means square hollow section. Unlike an open structural shape, an SHS has a closed square profile with an outside width and depth, a wall thickness, and rounded corners. These geometric features are relevant when coordinating drawings, checking clearances, or using section-property data in design calculations.
The listed outer and inner corner radii describe the transition between the flat faces of the tube. They should be considered when preparing connection details, end cuts, fittings, or interfaces with other steelwork. The nominal dimensions alone do not describe every aspect of the finished profile.
Standard and delivery reference
The page identifies EN 10219-2 for dimensional tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. It also notes the relationship with EN 10219-1, which addresses technical delivery conditions. Link this reference with your project specification and material documentation rather than treating the profile designation as a complete procurement requirement.
Using the section data
- Use the dimension and radius entries when reviewing fabrication or detailing drawings.
- Use the sectional area and unit weight entries for reference during quantity, mass, and preliminary coordination work.
- Check the governing design standard, steel grade documentation, connection assumptions, corrosion requirements, and fabrication tolerances before final design approval.
CAD and drafting resource
A DWG download is provided for users developing layouts, model references, and steel detailing. Review the downloaded drawing against the project model and fabrication information before issuing production documentation.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a closed structural steel profile with square external geometry and hollow internal space.
Which standard is identified for this Hybox section?
The source reference identifies EN 10219-2 for dimensions, tolerances, and sectional properties, and explains that EN 10219-1 covers technical delivery conditions.
Why are the corner radii important?
Corner radii affect the actual profile geometry and can influence clearances, fit-up, connection detailing, and the interpretation of section-property data.
What information is available for the section?
The reference lists the profile dimensions, corner radii, sectional area, unit weight, and a DWG download for drafting and CAD coordination.
Can the listed properties be used as a complete structural design check?
No. The listed values are reference data. Final member and connection design should account for the governing standards, material documentation, loading, stability, fabrication, and project-specific requirements.
