The Hybox 355 SHS 50x50x3 is a square hollow section reference for structural steel design, drafting, and detailing. This page brings together the section dimensions, corner radii, sectional area, unit weight, applicable standard reference, and a downloadable DWG resource.
Use the dimensional data below when checking drawings, comparing hollow-section references, or preparing connection details. Any structural application should be verified against the governing design requirements and project-specific engineering calculations.
Hybox 355 SHS 50x50x3
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.

Sectional Area : 5.41 cm2
Unit Weight : 4.2 kg/m
How to read this SHS reference
SHS means square hollow section. The designation identifies a hollow steel profile with equal outside depth and width, while the thickness describes the wall dimension. The listed corner radii define the curved transition between the flat faces and are important when interpreting fabrication drawings or modelling the section in CAD.
The sectional area and unit weight are reference properties used in material takeoffs, mass estimates, and section comparisons. They should be kept distinct from design resistance, buckling capacity, or connection strength, which require additional engineering checks.
Standard and material-reference context
The source identifies 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 the relationship with EN 10219-1, which addresses technical delivery conditions. Refer to the applicable project specification and procurement documents when confirming material requirements.
For broader background, see related references on structural hollow sections, steel section properties, and EN 10219 terminology. These topics help connect the tabulated profile data with drafting, specification, and design workflows.
CAD and drafting use
The supplied DWG resource can support layout work, section libraries, and preliminary detailing. Check the drawing units, layer conventions, and project drafting standards before incorporating the file into a production document. A CAD outline is a geometric reference and does not replace fabrication tolerances or engineering verification.
