How to read this RHS reference
RHS is the common abbreviation for rectangular hollow section. The designation on this page identifies a rectangular profile by its depth, width, and wall thickness. The listed outer and inner corner radii describe the transition geometry at the section corners, which is important when coordinating clearances, offsets, end preparations, and connection details.
Section data and engineering use
The sectional area describes the steel area represented by the profile, while the unit weight supports material takeoff and weight coordination. These values should be read together with the dimensional information rather than treated as a substitute for project-specific structural checks.
For design work, the section reference may be used alongside resources covering RHS dimensions, steel section properties, structural steel connections, and CAD detailing. Verify orientation, end conditions, local connection effects, corrosion protection, and fabrication tolerances before using the section in a final design.
Standard and CAD reference
The source identifies EN 10210-2:2006-04 for dimensional tolerances, dimensions, and sectional properties for hot-finished structural hollow sections, with EN 10210-1 covering technical delivery conditions. The downloadable DWG can help with drafting and coordination, but the drawing should be checked against the project specification and the authoritative section data before issue.
Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section. It is a closed structural steel profile with a rectangular outside form and a hollow interior.
What information is provided for this Celsius 355 RHS?
The reference lists the profile designation, standard reference, depth, width, wall thickness, outer and inner corner radii, sectional area, and unit weight. It also provides a DWG download.
What is EN 10210-2 used for on this page?
EN 10210-2 is identified as the reference for dimensions, tolerances, and sectional properties of the hot-finished structural hollow section covered by this entry. It should be read with the stated technical delivery requirements where applicable.
Can the DWG file be used directly for structural design?
The DWG is a drafting and coordination resource. It does not replace engineering verification, project specifications, connection design, fabrication review, or confirmation of the applicable product documentation.
Why are the corner radii listed?
Corner radii define the curved transitions between the flat faces of the RHS. They can affect detailing clearances, fit-up, cutting, welding, and the way connected components meet the profile.
