The entry also provides the cited EN 10219 context and a downloadable DWG file for drafting workflows. For related guidance, connect this page with resources covering SHS terminology, sectional properties, steel hollow sections, and CAD/DWG detailing.
Hybox 355 SHS 50x50x2.5
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 : 50x50x2.5
Depth : 50 mm
Width : 50 mm
Thickness : 2.5 mm
Outer Corner Radius : 5 mm
Inner Corner Radius : 2.5 mm
Sectional Area : 4.59 cm2
Unit Weight : 3.6 kg/m
How to read the SHS designation
SHS means square hollow section. The designation 50x50x2.5 describes a square profile with the listed depth, width, and wall thickness. The source content separately identifies the outside and inside corner radii, which are important when interpreting the section outline in drawings or CAD models.
Reference standard and listed properties
The source cites EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. It also notes that EN 10219-1 addresses technical delivery conditions. Treat the dimensional and property values in the existing reference data as the controlling local information for this page.
The listed sectional area and unit weight can support quantity checks, detailing review, and preliminary reference work. They should not be treated as a complete design verification: member resistance, stability, connection behavior, material certification, fabrication tolerances, and project requirements must be checked separately by the responsible engineer.
Using the DWG reference
The linked DWG provides a practical starting point for drafting and layout. Before placing it in a project drawing, confirm the drawing units, layer conventions, scale, section orientation, and any project-specific detailing requirements. A CAD profile does not replace the governing project documents or engineering review.
Frequently asked questions
What does SHS mean?
SHS stands for square hollow section, a hollow structural steel profile with a square outside form and a continuous wall around the opening.
How should the 50x50x2.5 designation be read?
For this entry, the designation corresponds to the listed depth, width, and thickness values. The source content also gives separate outer and inner corner radii.
Which standard is referenced for this section?
The entry references EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties, and identifies EN 10219-1 as covering technical delivery conditions.
Can the DWG file be used directly in a project?
The DWG can be used as a drafting reference, but users should verify units, geometry, orientation, and project requirements before incorporating it into construction or fabrication documents.
Do the listed properties confirm that the section is suitable for a design?
No. The listed properties are reference data only. Suitability depends on the complete design, applied actions, stability checks, connections, material requirements, fabrication, and applicable project criteria.
