This reference page presents the published dimensions and section data for Hybox 355 square hollow section, designated 100x100x8. Use it when checking a steel shape schedule, reviewing a connection or detailing concept, or preparing drawings from the related CAD resource.
The listed values cover the section envelope, wall thickness, corner radii, sectional area, and unit weight. For broader context, see related guidance on SHS terminology, steel section properties, and structural steel connections.
Hybox 355 SHS 100x100x8
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 : 100x100x8
Depth : 100 mm
Width : 100 mm
Thickness : 8 mm
Outer Corner Radius : 20 mm
Inner Corner Radius : 12 mm
Sectional Area : 27.2 cm2
Unit Weight : 21.4 kg/m
How to read this SHS reference
The designation 100x100x8 identifies a square hollow section with equal outside depth and width and a stated wall thickness. The source also reports separate outer and inner corner radii, which are important when interpreting the actual profile geometry rather than treating the section as a sharp-cornered square.
Sectional area is the listed cross-sectional steel area. It is commonly used with other verified section properties during engineering checks, but it should not be treated as a complete design assessment by itself. Unit weight supports material quantity estimates and drawing or schedule coordination; fabrication, specification, and design decisions still require project-specific verification.
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 made from non-alloy and fine grain steels. It also notes that EN 10219-1 addresses technical delivery conditions. Consult the applicable project specification and current governing requirements before using a standard reference for procurement or design.
A DWG download is provided with this entry for drafting and coordination workflows. Confirm the drawing units, layer conventions, and geometry against the authoritative section data before incorporating the file into project documents. Related resources may include structural steel CAD blocks and section-detailing guidance.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. Its outside profile has equal depth and width, with a hollow interior and rounded corners.
What information is provided for this Hybox section?
The reference lists the designation, depth, width, thickness, outer and inner corner radii, sectional area, and unit weight.
Which standard is referenced?
The source references EN 10219-2:2006-04 for dimensions, tolerances, and sectional properties, and identifies EN 10219-1 as covering technical delivery conditions.
Is the DWG file suitable for design verification?
The DWG is a drafting and coordination resource. It should be checked against the listed section data and the project specification; it does not replace engineering calculations or approval.
Can the listed section data alone confirm structural capacity?
No. Capacity depends on the design situation, material requirements, restraint, connections, applicable design rules, and other project conditions. A qualified engineer should verify the complete application.
