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.

Depth : 200 mm
Width : 200 mm
Thickness : 6.3 mm
Outer Corner Radius : 15.8 mm
Inner Corner Radius : 9.4 mm
Sectional Area : 47.4 cm2
Unit Weight : 37.2 kg/m
Understanding the SHS designation
SHS means square hollow section. In the designation 200x200x6.3, the first two values identify the nominal outside depth and width, while the final value identifies the wall thickness. The source content lists these dimensions separately, making the section easier to check against drawings, schedules, and connection details.
How to read the listed section data
The outer and inner corner radii describe the rounded transitions between the flat faces of the hollow section. These radii matter when checking clearances, detailing welded or bolted connections, and interpreting CAD geometry. The listed sectional area and unit weight are useful reference values for material takeoffs and section-property workflows; they should be used exactly as presented in the source data.
Standard reference and delivery context
The page references 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. The source also notes that this reference complements EN 10219-1, which addresses technical delivery conditions. Check the applicable project documentation before relying on a standard reference for fabrication, inspection, or design decisions.
CAD and drafting workflow
The downloadable DWG can support preliminary drafting, section-library development, and coordination. Before issuing a drawing, verify the section orientation, corner geometry, units, layer conventions, and any connection-specific modifications against the project requirements. A CAD profile is a drafting aid and does not replace engineering checks for strength, stability, fabrication, or connection performance.

Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow structural profile with nominally square outside dimensions.
How should 200x200x6.3 be read?
The designation identifies the listed outside depth, outside width, and wall thickness. The source content gives the corresponding values separately for verification.
What corner radii are listed for this section?
The source lists both an outer corner radius and an inner corner radius. Refer to the existing technical content for their exact values when checking geometry or preparing details.
Which standard is referenced on this page?
The page references EN 10219-2:2006-04 for dimensions, tolerances, and sectional properties, and notes its relationship to EN 10219-1 for technical delivery conditions.
Is the DWG ready for construction issue?
The DWG is a useful drafting reference, but it should be checked for units, geometry, project conventions, and connection-specific requirements before being used in an issued drawing.
Can the listed unit weight be used for a final design?
The listed unit weight can support reference and quantity-checking workflows. Final design, procurement, and fabrication decisions require verification against the governing project documents and engineering requirements.
