Celsius 355 RHS 160x80x6.3 is a hot-finished rectangular hollow section reference for engineers, detailers, fabricators, and CAD users working with structural steel sections. The page preserves the listed dimensions, corner radii, sectional area, and unit weight from the local reference data.
Use the dimensional information with the accompanying section-property data when reviewing drawings, comparing hollow-section references, or preparing connection and detailing documentation. The downloadable DWG provides a practical starting point for drafting, but project use still requires checking the applicable design requirements and fabrication details.

Depth : 160 mm
Width : 80 mm
Thickness : 6.3 mm
Outer Corner Radius : 9.4 mm
Inner Corner Radius : 6.3 mm
Sectional Area : 28.2 cm2
Unit Weight : 22.1 kg/m
Understanding the RHS designation
RHS means rectangular hollow section. In the designation 160x80x6.3, the first two values identify the rectangular outside profile dimensions and the final value identifies the wall thickness, as listed in the source data. The section has a larger depth than width, so its orientation should be confirmed when it is placed in a drawing or modeled in a structural system.
What the listed properties describe
- Depth and width: These define the outside rectangular profile used for identification and drafting.
- Thickness: This identifies the section wall dimension shown in the reference.
- Corner radii: The outer and inner corner-radius entries describe the rounded transitions between the flat faces of the hollow section. These details matter when checking clearances, detailing connections, and interpreting a CAD profile.
- Sectional area: This is the cross-sectional steel area reported for the section and is used as an input in engineering calculations.
- Unit weight: This expresses the listed mass per unit length and can support estimating, handling, and material scheduling activities.
Standard and drafting context
The reference identifies EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. It also points to EN 10210-1 for technical delivery conditions. Reviewers should confirm that the standard reference, material designation, tolerances, and fabrication requirements match the project documentation before release.
Related reference topics
This page connects naturally with rectangular hollow sections, hollow-section corner geometry, steel section properties, connection detailing, and CAD or DWG workflows. Those topics help explain how a catalogued section is carried from a dimensional reference into a coordinated engineering drawing without treating the reference data as a substitute for project-specific verification.
Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section, a steel profile with a rectangular outside form and a hollow interior.
How is Celsius 355 RHS 160x80x6.3 identified?
The reference identifies the section by its Celsius 355 designation and its listed depth, width, and wall thickness: 160 mm, 80 mm, and 6.3 mm respectively.
Why are the corner radii listed?
Corner radii describe the curved transitions between the flat faces of the section. They help users interpret the actual profile for drafting, clearance checks, and connection detailing.
