This reference covers a Celsius 355 rectangular hollow section (RHS) identified as 100x60x3.2. Use the source values below when checking the section geometry, sectional area, unit weight, and corner radii for estimating, detailing, or CAD coordination.
The page also provides context for EN 10210-2:2006-04 and includes a DWG resource for users working with structural steel shapes and drafting references. Always verify the selected section and project requirements before using the information in engineering design.
Celsius 355 RHS 100x60x3.2
Celsius 355 Rectangular Hollow Sections
refer to : EN 10210-2:2006-04
the European standard that specifies tolerances, dimensions, and sectional properties for hot-finished structural hollow sections of non-alloy and fine grain steels. It supports EN 10210-1, which covers technical delivery conditions.
Dimension : 100x60x3.2
Depth : 100 mm
Width : 60 mm
Thickness : 3.2 mm
Outer Corner Radius : 4.8 mm
Inner Corner Radius : 3.2 mm
Sectional Area : 9.72 cm2
Unit Weight : 7.6 kg/m
How to read the RHS designation
The designation 100x60x3.2 identifies the rectangular hollow section by its listed depth, width, and wall thickness. The source separates these dimensions so they can be checked individually against drawings, schedules, and section-property references.
What the listed properties mean
Outer and inner corner radii describe the rounded transitions at the corners of the hollow section. These details matter when coordinating accurate profiles in fabrication drawings, CAD models, and connection details.
Sectional area represents the steel area in a cross-section. Unit weight expresses the listed mass per metre, which is useful for material takeoffs and preliminary weight estimates. Neither value alone establishes the capacity of a member; design checks must also consider the loading, restraint, connection details, material requirements, and applicable project rules.
Standard and drafting reference
The cited EN 10210-2 reference is associated with dimensions, tolerances, and sectional properties for hot-finished structural hollow sections. The linked DWG can support drafting and layout work, but users should check the drawing against the source dimensions and the requirements of the project before issuing fabrication or construction documents.

Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section. It is a hollow structural steel profile with a rectangular outside shape and rounded corners.
What do the numbers 100x60x3.2 describe?
They identify the listed section depth, width, and wall thickness, respectively. The source provides each dimension separately for reference.
Why are the corner radii included?
Corner radii help describe the actual profile geometry. They are useful when preparing accurate CAD models, checking clearances, and developing connection or fabrication details.
What is the unit weight used for?
The listed unit weight is a mass-per-length reference that can support material takeoffs and preliminary estimates. It should not be treated as a substitute for a complete structural design check.
Is the DWG ready for fabrication?
The DWG is a drafting reference. Review its geometry against the source data, project requirements, and fabrication procedures before relying on it for issued documents.
