This reference page presents the published dimensions and section data for Hybox 355 SHS 140x140x5, a square hollow section listed with an EN 10219-2 reference. Use the information below to check terminology, coordinate drafting work, and identify the accompanying DWG resource.
The existing source data is the controlling reference for the section’s dimensions, corner geometry, sectional area, and unit weight. Any use in structural design, fabrication, or connection detailing should be checked against the applicable project requirements and verified by a qualified engineer.
Hybox 355 SHS 140x140x5
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 : 140x140x5
Depth : 140 mm
Width : 140 mm
Thickness : 5 mm
Outer Corner Radius : 10 mm
Inner Corner Radius : 5 mm
Sectional Area : 26.4 cm2
Unit Weight : 20.7 kg/m
How to read the SHS designation
SHS means square hollow section. The 140x140x5 designation identifies the nominal outside depth, nominal outside width, and wall thickness shown in the source data. Because the section is hollow and square, its outside depth and width are listed as the same dimension.
Dimensions and corner geometry
The page records the section depth, width, and thickness together with separate outer and inner corner radii. These radii describe the curved transitions at the corners rather than sharp outside or inside corners. That distinction matters when checking clearances, preparing fabrication details, or comparing CAD geometry with a dimensional reference.
Sectional area and unit weight
The listed sectional area is a cross-sectional property, while the unit weight describes the mass assigned per unit length in the source data. These values are useful reference points for quantity takeoffs, model checking, and preliminary comparison with other hollow sections. They should not be treated as a substitute for project-specific material, fabrication, or design verification.
Standard reference and CAD resource
The source refers to EN 10219-2:2006-04 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. It also distinguishes this dimensional reference from EN 10219-1, which covers technical delivery conditions. The linked DWG file can support drafting and coordination workflows; users should confirm units, layer conventions, and geometry before incorporating it into project documentation.

Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow steel section with a square outside profile.
What does 140x140x5 identify?
It identifies the nominal outside depth, nominal outside width, and wall thickness listed for this section. The source gives these as 140 mm, 140 mm, and 5 mm.
Why are outer and inner corner radii listed separately?
The outer and inner corners have different radii because the wall forms a curved corner transition. Both values are relevant when comparing section references or checking detailed CAD geometry.
Which standard is referenced for this section?
The source references EN 10219-2:2006-04 for dimensions, tolerances, and sectional properties. It notes that EN 10219-1 covers technical delivery conditions.
Is a DWG file available?
Yes. The page includes a linked DWG resource for Hybox 355 SHS 140x140x5. Review the file before use to confirm that its geometry and drafting conventions match the project requirements.
Can the listed unit weight be used directly for design?
The listed unit weight is a reference value for this section. Final design, fabrication, and quantity decisions should account for the governing project documents and professional verification.
