Understanding the Hybox 355 SHS designation
SHS means square hollow section. The designation identifies a hollow steel profile with equal outside depth and width, while the final part of the designation identifies the listed wall thickness. The source entry reports the corresponding overall dimensions and corner radii, which are important when representing the profile accurately in drawings or checking clearances at connections.
What the listed properties mean
The dimensional data describes the physical envelope of the section. The outer corner radius and inner corner radius describe the curved transitions between the flat faces rather than treating the section as a sharp-cornered square.
The sectional area is a geometric property used in calculations involving the steel material in the cross-section. The unit weight supports estimating the line weight of the member for material takeoffs and coordination. These values should be used together with the applicable design rules and verified project data; they do not by themselves establish resistance, stability, or connection capacity.
Referenced standard and drafting use
The entry refers to EN 10219-2:2006-04 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. Review the applicable project specification and supplied material documentation before treating a reference value as a procurement or fabrication requirement.
The downloadable DWG resource can help with CAD layout, section callouts, connection detailing, and drawing coordination. When inserting the profile into a model, check the drawing units, insertion scale, corner geometry, and orientation. Related SteelSTD resources on steel shapes, hollow sections, section properties, and steel connections can provide useful background for interpreting the entry.
Practical checking workflow
- Confirm that the SHS designation matches the member shown on the drawing or schedule.
- Compare the listed depth, width, and thickness with the intended CAD profile.
- Account for the corner radii when checking fit-up, clearances, and connected plate geometry.
- Use the sectional area and unit weight consistently in estimating and engineering calculations.
- Verify material documentation, tolerances, and design assumptions before fabrication or construction.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow structural steel profile with equal outside depth and width.
What are the listed dimensions of this Hybox 355 section?
The source identifies the section as 150x150x10 and lists a depth of 150 mm, a width of 150 mm, and a thickness of 10 mm.
Why are the corner radii included?
Corner radii describe the curved transitions between the flat faces of the hollow section. They help produce a more accurate CAD representation and support clearance and connection-detailing checks.
What information is provided for estimating?
The entry provides a sectional area and unit weight. These values can support material takeoffs and preliminary comparisons, subject to project and engineering verification.
Which standard is referenced?
The entry refers to EN 10219-2:2006-04 and notes its relationship with EN 10219-1. Consult the applicable project documentation for the requirements governing supply, tolerances, and design.
Is a CAD file available?
Yes. The page includes a DWG download for the Hybox 355 SHS 150x150x10 profile. Check units and scale before using it in a project drawing.
