Hybox 355 SHS 200x200x12.5
Hybox 355 Square Hollow Sections
refer to : EN 10219-2:2006-04
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 : 200x200x12.5
Depth : 200 mm
Width : 200 mm
Thickness : 12.5 mm
Outer Corner Radius : 37.5 mm
Inner Corner Radius : 25 mm
Sectional Area : 87 cm2
Unit Weight : 68.3 kg/m
How to read the section designation
The designation identifies a Hybox 355 square hollow section and gives its outside width, outside depth, and wall thickness. Because the section is square, the listed depth and width are equal. The source data also identifies the outside and inside corner radii, which are important when a section is represented in CAD or checked against a connection detail.
What the listed properties mean
Sectional area describes the steel area in a cross-section and is used as an input for calculations such as axial resistance and mass-related checks. Unit weight expresses the listed mass per unit length and can support estimating, handling, transport, and material takeoff work.
Corner radii affect the actual profile geometry rather than the nominal envelope dimensions. For accurate drawings, fabrication details, and connection layouts, use the published dimensions and the downloadable DWG together rather than substituting a sharp-cornered square in a model.
Standards and CAD reference
The source cites EN 10219-2 for dimensions, tolerances, and sectional properties, while identifying EN 10219-1 as the related standard for technical delivery conditions. Always check the project specification and the applicable design rules before using a section in a structural calculation.
The available DWG download can support drafting and coordination. Confirm units, layer conventions, and project-specific detailing requirements before inserting the file into production documentation.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow structural profile with square nominal outside dimensions and a wall thickness.
What dimensions are listed for this Hybox section?
The source lists the nominal dimension as 200x200x12.5, with depth, width, thickness, and separate outside and inside corner radii provided in the technical data.
Which standard is referenced?
The page references EN 10219-2 for dimensions, tolerances, and sectional properties, and notes the relationship to EN 10219-1 for technical delivery conditions.
What is the DWG used for?
The DWG provides a CAD reference for the section profile. Review the drawing setup and project requirements before using it for fabrication or issued design documentation.
Can the listed section data replace a structural design check?
No. The listed dimensions and properties are reference information. Member resistance, stability, connection behavior, fire performance, and other design checks require the applicable project criteria and engineering verification.
