The Hybox 355 RHS 50x30x2 is a rectangular hollow section with a 50 mm depth, 30 mm width, and 2 mm wall thickness. This reference brings the profile dimensions, corner radii, sectional area, unit weight, standard reference, and CAD download together for design and drafting workflows.
Use the dimensional data below when identifying the section in a drawing or section schedule. For design work, confirm the relevant material, loading, connection details, and code requirements with the project engineer rather than relying on profile dimensions alone.
Hybox 355 RHS 50x30x2.0
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 : 50x30x2
Depth : 50 mm
Width : 30 mm
Thickness : 2 mm
Outer Corner Radius : 4 mm
Inner Corner Radius : 2 mm
Sectional Area : 2.94 cm2
Unit Weight : 2.3 kg/m
How to read the Hybox 355 RHS designation
RHS means rectangular hollow section. The profile designation identifies the nominal outside depth, outside width, and wall thickness. For this section, the source data lists the dimensions as 50x30x2, with the larger outside dimension representing the depth and the smaller dimension representing the width.
Section geometry and reference properties
The source lists an outer corner radius of 4 mm and an inner corner radius of 2 mm. These radiused corners distinguish a formed hollow section from a sharp-cornered rectangle and should be considered when checking clearances, detailing connections, or preparing fabrication drawings.
The listed sectional area is 2.94 cm2, and the listed unit weight is 2.3 kg/m. These values are useful for material takeoffs, preliminary comparisons, and drawing references. They should not be treated as a substitute for the complete design checks required for a structural application.
Standard and CAD reference
The source refers to 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. Review the project specification and the applicable material documentation before accepting a section for procurement or fabrication.
A DWG file is provided with this entry for drafting reference. Before using the geometry in production drawings, verify the downloaded file against the authoritative dimensions and the requirements of the project.
