RHS 200x80x6 is a cold-formed welded rectangular hollow section for engineering reference, drafting, and preliminary section selection. This page lists the source dimensions, corner radii, sectional area, and unit weight for the section.
Use the dimensional data together with the applicable material specification, design standard, connection details, fabrication requirements, and project conditions. The listed section values are reference data and should not be treated as a complete structural design check.
RHS 200x80x6
Cold Formed Welded Rectangular Steel Tubes
refer to : EN 10219-2
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.

Understanding the RHS 200x80x6 designation
RHS means rectangular hollow section. In the designation 200x80x6, the first dimensions identify the rectangular outside profile and the final dimension identifies the wall thickness. The source data gives a depth of 200 mm, a width of 80 mm, and a thickness of 6 mm.
Geometry and reference properties
The section includes an outer corner radius of 12 mm and an inner corner radius of 6 mm. Corner geometry is important when interpreting drawings, checking clearances, detailing end connections, and comparing catalog data between manufacturers.
The listed sectional area and unit weight are useful for quantity estimates, member schedules, preliminary comparisons, and drafting references. They do not, by themselves, establish resistance, stiffness, buckling performance, weld capacity, or connection adequacy.
Standard reference and design use
The source refers to EN 10219-2 for dimensional, tolerance, and sectional-property information for cold-formed welded structural hollow sections. Material delivery requirements are associated with the related EN 10219-1 reference identified in the source content.
For project use, confirm the material grade, manufacturing tolerances, design assumptions, corrosion protection, fabrication method, and connection configuration against the governing project documents. The downloadable DWG can support layout and detailing workflows, but drawings should be checked against the project’s approved dimensions and fabrication requirements.
Frequently asked questions
What does RHS 200x80x6 mean?
It identifies a rectangular hollow section with the source-listed depth, width, and wall thickness of 200 mm, 80 mm, and 6 mm respectively.
What type of product is RHS 200x80x6?
The source describes it as a cold-formed welded rectangular steel tube or structural hollow section.
Which standard is referenced for this section?
The source refers to EN 10219-2 for dimensions, tolerances, and sectional properties, and identifies EN 10219-1 for technical delivery conditions.
Can the listed unit weight be used as a design capacity?
No. Unit weight supports estimating and scheduling. Structural design also requires material, stability, member actions, connection behavior, and applicable project checks.
