This reference page summarizes the published geometry and section data for the Hybox 355 SHS 200x200x10. Use it alongside the dimensional information below when checking layouts, preparing drawings, or comparing square hollow sections.
The designation identifies a square hollow section (SHS) with equal nominal depth and width and a stated wall thickness. The page also provides corner radii, sectional area, unit weight, the listed European standard reference, and a CAD download.
Hybox 355 SHS 200x200x10
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 : 200x200x10
Depth : 200 mm
Width : 200 mm
Thickness : 10 mm
Outer Corner Radius : 25 mm
Inner Corner Radius : 15 mm
Sectional Area : 72.6 cm2
Unit Weight : 57 kg/m
How to read the Hybox 355 SHS designation
SHS means square hollow section. Unlike an open steel profile, the section has a closed square outline. In the designation 200x200x10, the first two dimensions describe the nominal outside depth and width, while the final dimension identifies the wall thickness. The source content lists these values separately for clarity.
Why the corner radii matter
The outer and inner corner radii describe the rounded transitions at the section corners. These radii are important when coordinating connected parts, checking clearances, preparing fabrication details, or comparing the section with CAD geometry. They should not be replaced by sharp-corner assumptions without confirming the requirements of the specific calculation or detail.
Using the section properties
The listed sectional area is a cross-sectional reference property, while the unit weight supports material quantity and handling estimates. Neither value should be treated as a complete design check. Structural resistance, stability, connection behavior, fabrication requirements, and applicable project rules require verification by a qualified engineer.
Standard and CAD reference
The source identifies EN 10219-2:2006-04 for dimensional, tolerance, and sectional-property information and distinguishes it from EN 10219-1, which addresses technical delivery conditions. Review the project’s specified material documentation and design basis rather than relying on a profile name alone.
The linked DWG file can help with drafting and layout coordination. Check the drawing units, layer conventions, insertion point, and geometry against the authoritative source data before incorporating it into production documents.

Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a closed steel section with a square profile.
What are the nominal dimensions of this section?
The source lists a depth of 200 mm, a width of 200 mm, and a thickness of 10 mm.
Why are both inner and outer corner radii listed?
The two radii describe the inside and outside curvature at the section corners. They are useful for accurate detailing, clearance checks, and CAD coordination.
Which standard is referenced?
The source refers to EN 10219-2:2006-04 for the listed dimensional and sectional information and notes the relationship to EN 10219-1.
Is a DWG file available?
Yes. The page includes a downloadable DWG reference for the Hybox 355 SHS 200x200x10 profile. Verify the file against the published source values before use.
