The Hybox 355 SHS 140x140x4 is a square hollow section reference for structural steel design and drafting work. This page brings together the profile dimensions, corner radii, sectional area, unit weight, applicable standard reference, and a downloadable DWG file.
Use the listed values as a quick reference when reviewing square hollow sections, comparing section geometry, or preparing preliminary CAD details. Final selection and connection design should be checked against the project specification and applicable engineering requirements.
Hybox 355 SHS 140x140x4
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 : 140x140x4
Depth : 140 mm
Width : 140 mm
Thickness : 4 mm
Outer Corner Radius : 8 mm
Inner Corner Radius : 4 mm
Sectional Area : 21.3 cm2
Unit Weight : 16.7 kg/m
How to read this SHS reference
The designation 140x140x4 identifies the nominal outside depth, nominal outside width, and wall thickness of the square section. The profile listing also gives the outer and inner corner radii, which describe the rounded transitions between the flat faces of the hollow section.
The sectional area is a geometric property used in section calculations, while the unit weight expresses the listed mass per metre. These properties support estimating and comparison tasks, but they do not by themselves establish a member’s resistance, serviceability, or suitability for a particular structure.
Standard and drafting context
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 the relationship with EN 10219-1, which addresses technical delivery conditions. When using this profile in a project, confirm the required material documentation, fabrication tolerances, design code, and connection details.
For drafting workflows, the supplied DWG download can help with layout and detailing. Check the downloaded geometry against the project model and manufacturer or fabricator information before using it for fabrication documentation.

Frequently asked questions
What does SHS mean?
SHS means square hollow section, a structural steel profile with a square outside shape and a hollow interior.
What does 140x140x4 describe?
It identifies the listed nominal outside depth, nominal outside width, and wall thickness: 140 mm, 140 mm, and 4 mm respectively.
What standard is referenced for this profile?
The source references EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections. It also identifies EN 10219-1 as covering technical delivery conditions.
What is the difference between sectional area and unit weight?
Sectional area is a geometric property of the steel cross-section. Unit weight describes the listed mass per metre. Neither value alone replaces the engineering checks required for member design or connections.
Is a DWG file available?
Yes. The page includes a DWG download for the Hybox 355 SHS 140x140x4 profile. Review the file against the project model and approved fabrication information before issuing drawings.
