The Hybox 355 SHS 60x60x3 is a square hollow section reference entry for engineers, detailers, fabricators, and CAD users. This page brings together the listed section dimensions, corner radii, sectional area, unit weight, and the cited European standard so the profile can be identified consistently during design development and detailing.
Use the dimensional information with the associated material and project requirements. The tabulated section data supports reference and coordination, but it does not by itself establish resistance, stability, connection performance, or design suitability.

Depth : 60 mm
Width : 60 mm
Thickness : 3 mm
Outer Corner Radius : 6 mm
Inner Corner Radius : 3 mm
Sectional Area : 6.61 cm2
Unit Weight : 5.2 kg/m
Understanding the Hybox 355 square hollow section
SHS means square hollow section: the outside profile is square, with a hollow interior and rounded corners. The listed depth and width describe the outside envelope, while the wall thickness describes the nominal material thickness used to identify the section. These dimensions are useful when checking clearances, intersections, end conditions, and architectural or fabrication layouts.
Why the corner radii matter
The outer and inner corner radii are part of the profile geometry rather than optional drafting details. They affect how the section meets plates, fittings, weld preparations, and adjacent members. A CAD drawing should therefore preserve the stated corner form instead of representing the section as a sharp-cornered square.
Using the listed section properties
The sectional area and unit weight provide reference information for quantity takeoffs, preliminary coordination, and comparison with other hollow sections. They should not be treated as a complete design check. Member resistance, buckling, fire performance, connection behavior, and fabrication requirements depend on the governing design basis and project conditions.
Standard reference and CAD resource
The source identifies EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. It also distinguishes EN 10219-1 as the standard covering technical delivery conditions. Review the applicable project specification and current requirements before using a standard reference for procurement or design documentation.
The downloadable DWG is useful for drafting and coordination. Check the drawing units, layer conventions, insertion point, and project-specific detailing requirements before incorporating it into production documents. Related site resources on SHS terminology, hollow-section connections, steel section properties, and DWG workflows can provide useful background.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow steel profile with a square outside form and rounded corners.
What information is listed for this Hybox section?
The reference lists the section designation, dimensions, outer and inner corner radii, sectional area, and unit weight. It also identifies the associated EN 10219-2 reference.
What is the role of EN 10219-2 in this entry?
It is cited for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. The source separately identifies EN 10219-1 for technical delivery conditions.
Can the DWG be used directly for fabrication?
The DWG is a drafting and coordination resource. Confirm units, geometry, project standards, fabrication requirements, and the applicable design documentation before using it in issued drawings.
Do the listed area and unit weight prove structural capacity?
No. They are reference properties for the listed section. Capacity and performance require a complete engineering assessment that considers material, loading, restraint, member behavior, connections, and governing requirements.
