Depth : 90 mm
Width : 90 mm
Thickness : 5 mm
Outer Corner Radius : 10 mm
Inner Corner Radius : 5 mm
Sectional Area : 16.4 cm2
Unit Weight : 12.9 kg/m
How to read the Hybox 355 SHS designation
SHS means square hollow section. The designation 90x90x5 identifies the section dimensions shown in the source entry: depth, width, and wall thickness. Because the section is square, the listed depth and width are equal.
The entry also identifies an outer corner radius and an inner corner radius. These values describe the rounded transitions between the flat faces of the hollow section and are relevant when interpreting geometry, preparing fabrication details, or comparing section-property references.
Standard reference and section data
The source refers to EN 10219-2:2006-04 for dimensional tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. It also notes the relationship with EN 10219-1, which addresses technical delivery conditions. Consult the complete standard and project specifications when tolerance, material, inspection, or delivery requirements affect the application.
For design checks, use the listed sectional area and unit weight as reference data from the local table. These properties should not be treated as a substitute for the applicable design code, material certification, connection checks, stability assessment, or engineer-of-record review.
DWG reference for drafting
The supplied DWG download can support CAD coordination and preliminary detailing. Verify units, layer conventions, drawing orientation, and the intended use of the file before incorporating it into a production drawing. A CAD outline does not by itself confirm manufacturing tolerances or design adequacy.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow steel profile with square external geometry and rounded corners.
What do the dimensions 90x90x5 represent?
They identify the depth, width, and wall thickness recorded for this Hybox 355 section. The source entry provides the corresponding dimensional values and corner radii.
Which standard is referenced for this section?
The entry refers to EN 10219-2:2006-04 and explains that it addresses dimensions, tolerances, and sectional properties for cold-formed welded structural hollow sections. It also identifies EN 10219-1 as the related reference for technical delivery conditions.
Can the DWG file be used directly for structural design?
The DWG is a drafting reference and should be checked before use. Structural design still requires verification of material, tolerances, loading, connections, stability, and applicable project standards by a qualified engineer.
