Hybox 355 SHS 50x50x5 is a square hollow section reference for checking the listed dimensions, corner geometry, sectional area, and unit weight of this cold-formed welded structural section. The page also identifies the cited EN 10219-2 reference and provides access to a DWG file for drafting workflows.
Use the source values below as the controlling local reference. For design work, connect this dimensional information with the applicable steel section properties, material requirements, connection details, and project design checks rather than treating the profile designation alone as a capacity statement.

How to read the Hybox 355 SHS reference
SHS means square hollow section. The 50x50x5 designation identifies the listed outside depth, outside width, and wall thickness. Because the section is hollow, its behavior and detailing differ from those of a solid bar or an open structural shape. The source also gives the outside and inside corner radii, which are important when modeling the profile accurately or checking fit-up at connections.
Dimensions, area, and unit weight
The dimensional entries describe the profile envelope and wall thickness, while the sectional area represents the steel area through a transverse cut. The listed unit weight provides the mass-per-length reference used for quantity takeoffs and related drafting or estimating tasks. These values should be kept consistent with the selected section and the governing project documentation.
EN 10219-2 reference
The source cites EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections made from non-alloy and fine grain steels. It also notes that EN 10219-1 covers technical delivery conditions. Always verify the applicable project specification and current compliance requirements before using a standard reference for procurement or design.
DWG download and drafting use
The linked DWG resource can support CAD layouts, section details, and coordination drawings. Confirm the drawing units, insertion scale, layer conventions, and profile orientation when importing it into a project. A CAD outline is a drafting aid; it does not replace the project’s approved material, fabrication, tolerance, or connection information.

Frequently asked questions
What does SHS mean in this reference?
SHS means square hollow section. It describes a closed, square-profile structural steel shape with the dimensions and corner radii listed in the source content.
What does 50x50x5 describe?
In this page’s designation, 50×50 identifies the listed outside depth and width, while 5 identifies the listed wall thickness. Refer to the source values for the complete dimensional description.
Why are the corner radii listed?
Corner radii describe the rounded transitions between the flat faces of the hollow section. They help with accurate CAD representation, connection detailing, fabrication coordination, and dimensional checks.
What is the sectional area used for?
Sectional area is the steel area through a cross-section. It is commonly used as an input to engineering calculations and quantity-related checks, but it does not by itself establish member resistance or design suitability.
Is the DWG file a design approval?
No. The DWG is a drafting resource for representing the profile. Engineering design, material verification, fabrication requirements, tolerances, and connection checks must follow the applicable project documents and qualified engineering review.
Which standard is cited for this Hybox 355 SHS page?
The source cites EN 10219-2:2006-04 and explains that EN 10219-1 addresses technical delivery conditions. Confirm the governing specification and applicable edition for the project before procurement or compliance decisions.
