Hybox 355 RHS 80x60x3 is a rectangular hollow section reference for checking the listed outside dimensions, wall thickness, corner geometry, sectional area, and unit weight. The page also identifies the applicable standard context and provides a DWG resource for drafting workflows.
Use the dimensional data below when reviewing rectangular hollow sections, comparing steel shape references, or preparing connection and detailing drawings. Confirm design resistance, stability, fabrication requirements, and material certification through the project engineer and the applicable project documentation.
Hybox 355 RHS 80x60x3.0
Hybox 355 Rectangular 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 : 80x60x3
Depth : 80 mm
Width : 60 mm
Thickness : 3 mm
Outer Corner Radius : 6 mm
Inner Corner Radius : 3 mm
Sectional Area : 7.81 cm2
Unit Weight : 6.1 kg/m
How to read this RHS reference
The designation 80x60x3 describes the listed rectangular section dimensions and wall thickness. In the source data, the depth is 80 mm, the width is 60 mm, and the thickness is 3 mm. The outer and inner corner radii describe the rounded transitions between the flat faces rather than a sharp-cornered profile.
The listed sectional area and unit weight are useful for quantity checks, preliminary comparisons, and coordination between structural calculations and drawings. They should not be treated as a complete design check: resistance, buckling, connection behavior, corrosion allowance, fabrication tolerances, and load effects require project-specific engineering review.
Standard and drafting context
The reference 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. Review the complete project specification and material documentation when compliance is required.
The linked DWG file can support CAD coordination and detailing. Before issuing a drawing, verify units, layer conventions, section orientation, corner representation, and any fabrication notes against the project’s drafting standards. Related references may include RHS dimensions, structural hollow sections, steel section properties, and steel connection detailing.
Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section. It is a closed steel profile with rectangular external faces and rounded corners.
What are the listed dimensions of this Hybox 355 RHS?
The source lists a depth of 80 mm, a width of 60 mm, and a wall thickness of 3 mm. The designation is shown as Hybox 355 RHS 80x60x3.0 in the page content.
Why are the corner radii included?
Corner radii describe the curved geometry at the section corners. They help distinguish the actual hollow-section shape from a sharp-cornered rectangle and are relevant when reviewing sectional properties, detailing, and fabrication information.
Which standard is referenced?
The page references EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties, and explains that EN 10219-1 covers technical delivery conditions.
Is a DWG file available?
Yes. The page includes a linked DWG resource for the Hybox 355 RHS 80x60x3 section. Check the downloaded geometry and drawing units before using it in project documentation.
