Understanding the Hybox 355 SHS reference
SHS means square hollow section. The profile has a square outside form with a hollow interior, while the listed thickness and corner radii describe the section geometry used for drafting, fabrication, and section-property reference.
The cited EN 10219-2 reference concerns dimensions, tolerances, and sectional properties for cold-formed welded structural hollow sections. It should be read alongside the relevant technical delivery requirements identified in the source content. Standards references help users understand how the published dimensions and properties are organized; they do not replace project-specific verification.
How to use the listed data
- Dimensions: Use the depth, width, and thickness entries to identify the nominal profile in drawings and schedules.
- Corner radii: The outer and inner corner radius entries are useful when developing accurate CAD geometry, checking clearances, or reviewing fabrication details.
- Sectional area and unit weight: These are reference properties for quantity takeoffs and preliminary comparisons. Confirm the governing design basis before using them in calculations.
CAD and detailing workflow
The downloadable DWG provides a starting point for drafting this section. Review the drawing against the source dimensions before incorporating it into a project model, connection detail, fabrication drawing, or CAD/DWG reference library. Related guidance on section properties, steel connections, and structural steel terminology can help place the profile data in context.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow structural profile with a square outside shape.
Which standard is referenced for this profile?
The source references EN 10219-2:2006-04 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. The source also identifies EN 10219-1 as covering technical delivery conditions.
What information is provided for Hybox 355 SHS 40x40x3?
The reference lists the profile dimensions, outer and inner corner radii, sectional area, and unit weight. These values should be checked against the authoritative local table before use.
Can the DWG be used directly for fabrication?
The DWG is a drafting reference. Before fabrication, verify its geometry and project requirements against the source data, approved drawings, applicable standards, and the responsible engineer’s instructions.
Can the listed section properties be used as final design values?
Use the listed properties as reference data only until the applicable design standard, material requirements, tolerances, connection behavior, and project conditions have been verified.
