This reference identifies the Hybox 355 SHS 100x100x4 square hollow section and summarizes the dimensional and section data provided in the source record. It is intended for engineers, detailers, fabricators, and CAD users checking a structural hollow-section designation.
Use the listing below together with the applicable project specification, material documentation, and engineering checks. The dimensional data and section properties shown in the existing record remain the controlling local reference for this page.
Hybox 355 SHS 100x100x4
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 : 100 mm
Width : 100 mm
Thickness : 4 mm
Outer Corner Radius : 8 mm
Inner Corner Radius : 4 mm
Sectional Area : 14.9 cm2
Unit Weight : 11.7 kg/m
How to read this SHS reference
SHS means square hollow section. The designation describes a hollow square profile, while the dimension entry identifies the outside size and wall thickness used to distinguish this section from other square hollow sections.
The page separates the outside depth and width, wall thickness, and corner radii. Corner-radius information is important when interpreting the actual formed geometry, preparing fabrication details, or comparing the section with a CAD profile. The outside and inside radii describe different surfaces of the formed corner and should not be treated as interchangeable.
Section properties and mass information
The sectional area is a geometric property of the listed profile. It is useful when reviewing material quantity and carrying out engineering calculations, but it should be used with the applicable design method and material properties rather than treated as a complete design check.
The listed unit weight expresses the mass associated with a unit length of the section. It can support estimating, scheduling, and checking model quantities. Actual procurement and fabrication documentation should still be checked for applicable tolerances, manufacturing conditions, and project requirements.
Standard and CAD reference
The source identifies EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections, and notes its relationship to EN 10219-1 for technical delivery conditions. Readers comparing products should review the complete applicable standard and supplier documentation rather than relying on the designation alone.
A DWG download is provided with this reference. Before using the drawing in production documentation, confirm the profile orientation, units, layer content, and project-specific drafting requirements. Related internal references may include the SHS dimensions, structural hollow sections, section properties, EN 10219, and steel CAD/DWG downloads pages.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow structural profile with a square outside form and formed corners.
What information is included for this Hybox section?
The source record includes the section designation, standard reference, outside dimensions, wall thickness, corner radii, sectional area, and unit weight.
Why are both outer and inner corner radii listed?
They describe the two sides of the formed hollow-section corner. Keeping them separate helps with geometry interpretation, detailing, and CAD comparison.
What is the purpose of the EN 10219-2 reference?
In this listing, EN 10219-2 is identified in connection with tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections. The applicable project and supply requirements should also be reviewed.
Can the DWG file be used directly for fabrication?
The DWG is a reference drawing. Check its units and geometry against the project requirements and approved supplier or fabrication documentation before using it for production work.
