Hybox 355 SHS 90x90x3.0
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 : 90x90x3
Depth : 90 mm
Width : 90 mm
Thickness : 3 mm
Outer Corner Radius : 6 mm
Inner Corner Radius : 3 mm
Sectional Area : 10.2 cm2
Unit Weight : 8 kg/m
How to read the Hybox 355 SHS 90x90x3 reference
SHS means square hollow section. The listed depth and width are both 90 mm, while the wall thickness is 3 mm. The outer and inner corner radii describe the rounded transitions at the corners rather than sharp intersections. These details matter when interpreting drawings, checking clearances, or coordinating connections and fittings.
Section properties and material quantities
The source lists a sectional area of 10.2 cm2 and a unit weight of 8 kg/m. Sectional area is commonly used with section-property calculations, while unit weight is useful for estimating material quantities and checking steel takeoffs. These listed values should be kept distinct from project-specific design resistance, buckling checks, connection capacity, and fabrication allowances.
Standard reference and technical scope
The entry refers to 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. The source also identifies EN 10219-1 as covering technical delivery conditions. Consult the applicable project specification and current governing requirements before using a section in design or procurement.
DWG resource for drafting
The supplied DWG file can support CAD coordination, section-library preparation, and preliminary detailing. Confirm the drawing units, insertion scale, layer conventions, and project-specific detailing requirements before incorporating the file into a production drawing. Related SteelSTD resources on SHS dimensions, section properties, steel terminology, and connection detailing can help place this profile in a broader design workflow.
Frequently asked questions
What does SHS mean in this reference?
SHS means square hollow section. In this entry, the listed depth and width are both 90 mm, with a listed wall thickness of 3 mm.
What corner information is provided?
The reference gives an outer corner radius of 6 mm and an inner corner radius of 3 mm. Use these values when coordinating geometry or checking how the section fits with connection and detailing layouts.
What are the listed sectional area and unit weight?
The source lists a sectional area of 10.2 cm2 and a unit weight of 8 kg/m. They are reference values for section-property review and material quantity estimation, not a substitute for project-specific structural verification.
Which standard is referenced?
The entry refers to EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties, and notes that EN 10219-1 covers technical delivery conditions.
Is a CAD file available?
Yes. A DWG download is provided with the source entry. Review its units and drafting conventions before using it in a project drawing.
