The Hybox 355 SHS 100x100x3 is a square hollow section reference for checking the listed geometry and basic section data before drafting, estimating, or beginning a design review. This page keeps the manufacturer and standard-related information together with a downloadable DWG resource.
Use the dimension, thickness, corner-radius, sectional-area, and unit-weight entries below as the local reference data for this section. For design work, confirm the applicable material requirements, fabrication condition, loading, connection details, and code checks with the responsible engineer.
Hybox 355 SHS 100x100x3
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 : 100x100x3
Depth : 100 mm
Width : 100 mm
Thickness : 3 mm
Outer Corner Radius : 6 mm
Inner Corner Radius : 3 mm
Sectional Area : 11.4 cm2
Unit Weight : 8.9 kg/m
How to read the Hybox 355 SHS designation
SHS means square hollow section. The 100x100x3 designation identifies the listed outside depth and width together with the wall thickness. Because hollow-section geometry includes rounded corners, the outer and inner corner radii are also provided rather than treating the profile as a perfectly sharp-cornered box.
Understanding the reference properties
The sectional area is useful when reviewing material quantity and section-property data, while the unit weight supports preliminary mass estimates and handling considerations. These entries should be read with the stated dimensions and should not be substituted for project-specific checks of resistance, stability, deflection, fabrication, or connections.
Standard and drafting reference
The source identifies EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties, and distinguishes it from EN 10219-1, which addresses technical delivery conditions. Review the applicable project specification and current governing requirements before using a standard reference for procurement or design.
The downloadable DWG can support layout and detailing workflows. Check units, scale, layer conventions, corner geometry, and drawing compatibility before incorporating the file into a production drawing. Related topics such as structural steel shapes, hollow-section connections, section properties, and steel drafting standards can provide useful context when developing the detail.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a closed structural steel profile with a square outside form and a hollow interior.
What does 100x100x3 describe?
It identifies the listed outside depth, outside width, and wall thickness for this Hybox 355 section.
Why are corner radii included?
Corner radii describe the rounded transitions at the section corners. They are important when checking geometry, clearances, detailing, and CAD representation.
What is the role of EN 10219-2 in this reference?
The source associates EN 10219-2:2006-04 with tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections. The page also notes the related role of EN 10219-1 for technical delivery conditions.
Can the DWG be used directly for design?
The DWG is a drafting reference, not a substitute for engineering verification. Confirm the drawing geometry, units, material information, connection design, and project requirements before issuing design documentation.
