This page provides a focused reference for the Hybox 355 RHS 100x60x6 rectangular hollow section. The source information below identifies the overall dimensions, wall thickness, corner radii, sectional area, unit weight, and the referenced hollow-section standard.
Use the listed data when identifying the section in drawings, schedules, material takeoffs, or CAD libraries. The accompanying DWG can support drafting workflows, but its geometry, units, orientation, and layer conventions should be checked before it is incorporated into a project file.
Hybox 355 RHS 100x60x6
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 : 100x60x6
Depth : 100 mm
Width : 60 mm
Thickness : 6 mm
Outer Corner Radius : 12 mm
Inner Corner Radius : 6 mm
Sectional Area : 16.8 cm2
Unit Weight : 13.2 kg/m
How to Read This RHS Reference
RHS means rectangular hollow section. The designation 100x60x6 corresponds to the listed depth, width, and wall thickness. Because the profile is rectangular, its orientation matters: rotating the section changes which overall dimension is treated as the depth in a drawing or analysis model.
Key Geometry and Property Terms
- Depth and width: These describe the outside envelope of the rectangular section. Confirm the intended orientation when coordinating plans, elevations, sections, and local member axes.
- Thickness: The listed thickness describes the section wall and should not be confused with the overall profile dimensions.
- Outer and inner corner radii: RHS corners are rounded rather than perfectly square. These radii affect an accurate section outline and should be retained where profile geometry matters.
- Sectional area: This is the area of steel in the cross-section, not the area enclosed by the hollow interior.
- Unit weight: The listed value is a mass-per-length reference. Material estimates should also account for the actual member length and any project-specific fabrication considerations.
Standard Context
The source associates this section with EN 10219-2:2006-04, which addresses dimensional tolerances and section-property information for cold-formed welded structural hollow sections. The related delivery requirements are addressed separately by EN 10219-1, as noted in the source content.
A standard reference helps identify the dimensional framework behind the section, but it does not by itself establish member capacity or project suitability. Design checks still depend on the applicable design rules, material documentation, loading, member length, restraint, connections, and other project conditions.
Using the DWG in a Drafting Workflow
Before using the drawing, confirm that the imported file represents the intended Hybox 355 RHS 100x60x6 section. Check the CAD units, profile orientation, insertion point, corner geometry, and whether the object is drawn as closed geometry suitable for the intended workflow.
For section schedules and model coordination, keep the section designation consistent across drawings, specifications, calculations, and fabrication information. If software uses a different depth-by-width naming order, verify the local-axis orientation rather than relying only on the displayed label.

Frequently Asked Questions
What does Hybox 355 RHS 100x60x6 identify?
It identifies a Hybox 355 rectangular hollow section with the source-listed dimensions of 100x60x6.
What are the listed overall dimensions and thickness?
The source lists a depth of 100 mm, a width of 60 mm, and a thickness of 6 mm.
Why are corner radii included?
Rectangular hollow sections have formed corners rather than sharp square corners. The source lists an outer corner radius of 12 mm and an inner corner radius of 6 mm, which are relevant when checking detailed profile geometry.
What do the sectional area and unit weight represent?
The sectional area is the amount of steel present in the cross-section. The unit weight is the listed mass per unit length. For this section, the source gives 16.8 cm2 and 13.2 kg/m.
Which standard is referenced?
The source refers to EN 10219-2:2006-04 for dimensional tolerances and section-property information associated with cold-formed welded structural hollow sections.
What should be checked after downloading the DWG?
Verify the file units, profile dimensions, depth-to-width orientation, corner geometry, insertion point, and CAD layer or object structure before using it in a project drawing.
Does the section reference establish structural capacity?
No. The listed geometry and properties identify the section, but structural capacity requires project-specific engineering checks using the applicable design requirements, loading, restraint, member configuration, and connection details.
