Understanding the Hybox 355 SHS designation
SHS means square hollow section. The designation 160x160x8 identifies the nominal outside depth, nominal outside width, and wall thickness listed in the reference data. Because the outside dimensions are equal, the section is square in profile.
How to read the section reference
The dimension fields identify the basic envelope of the section, while the outer and inner corner radii describe the rounded transitions between the flat faces. These radii are important when creating accurate CAD geometry, checking clearances, detailing connections, or comparing measured sections with catalogue data.
The listed sectional area is useful when reviewing section-property information and material quantity. The unit weight describes the mass associated with a length of the section; it should not be treated as a structural resistance or allowable design load.
Standard reference and verification
The source refers to EN 10219-2:2006-04 for dimensional tolerances and sectional-property information for cold-formed welded structural hollow sections. It also identifies EN 10219-1 as covering technical delivery conditions. Confirm the applicable project requirements, material documentation, tolerances, and design basis before using the section in fabrication or structural calculations.
CAD and drafting use
The supplied DWG download can support layout, detailing, and coordination workflows. Check the drawing units, layer conventions, insertion point, and geometry against the project template before issuing drawings. The CAD file is a drafting resource and does not replace design calculations, fabrication documents, or engineer-approved connection details.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow structural profile with nominally equal outside width and depth.
What does 160x160x8 identify?
In this designation, the first two dimensions identify the listed outside depth and width, and the final dimension identifies the wall thickness.
Why are corner radii listed?
Corner radii define the curved transitions between the flat faces. They help produce more accurate CAD geometry and support dimensional checks, detailing, and section-property comparisons.
Which standard is referenced for this section?
The source references EN 10219-2:2006-04 for relevant dimensions, tolerances, and sectional-property information, with EN 10219-1 identified for technical delivery conditions.
Does the unit weight give the section’s design capacity?
No. Unit weight is a mass-per-length reference. Structural capacity depends on the material, loading, restraint, connection details, limit states, and applicable design rules, so it requires separate engineering verification.
