This page provides a focused reference for the Celsius 355 RHS 200x100x16 rectangular hollow section. The preserved section data identifies the overall dimensions, wall thickness, corner geometry, sectional area, unit weight, applicable dimensional reference, and the associated CAD resource.
Use the listed values when checking section identification, comparing rectangular hollow sections, coordinating drawing geometry, or preparing preliminary material schedules. Strength, connection design, fabrication tolerances, and project suitability must be verified using the governing project documents and appropriate engineering procedures.

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 : 200x100x16
Depth : 200 mm
Width : 100 mm
Thickness : 16 mm
Outer Corner Radius : 24 mm
Inner Corner Radius : 16 mm
Sectional Area : 83 cm2
Unit Weight : 65.2 kg/m
Understanding the RHS designation
RHS means rectangular hollow section. In the 200x100x16 designation, the values correspond to the listed depth, width, and wall thickness. Orientation matters in drawings and calculations because the section has different overall dimensions about its two principal directions.
The Celsius 355 name identifies the section range shown in the source content. The designation alone should not be used to infer an unlisted design strength, capacity, or material property. Those items require confirmation from the applicable product documentation and project specification.
How the listed properties are used
Sectional area represents the amount of steel in the cross-section. It is relevant to section-property calculations and provides a useful basis for checking other published data. Unit weight expresses mass per unit length and is commonly used for material takeoffs, handling studies, and estimates of member self-weight.
Neither sectional area nor unit weight is a member capacity. Structural resistance also depends on material properties, member length, support conditions, loading, local behavior, connection design, and the rules of the applicable design standard.
Corner radii and drawing accuracy
Rectangular hollow sections have rounded corners rather than perfectly square internal and external corners. The listed outer and inner corner radii help drafters represent the profile more accurately and can affect clearances, fitted plates, weld access, and connection detailing.
For general arrangement drawings, a simplified outline may be sufficient. For close-fit components or fabrication details, the actual corner geometry and manufacturer tolerances should be reviewed before dimensions are finalized.
Using the CAD resource
The preserved DWG download can support section layouts, drafting references, and detail development. After opening the file, confirm drawing units, profile orientation, layer organization, and agreement with the verified dimensions on this page. A section-profile drawing does not by itself define connection design, weld requirements, bolt arrangements, fabrication allowances, or structural capacity.

Frequently asked questions
What does Celsius 355 RHS 200x100x16 describe?
It identifies a rectangular hollow section in the named product range. The dimensional designation corresponds to the depth, width, and wall thickness reported in the preserved source data.
Why are both inner and outer corner radii listed?
The radii describe the rounded corner geometry on the outside and inside of the hollow section. They are useful when creating an accurate section profile or checking the fit of plates and nearby components.
Can unit weight be used to estimate member mass?
Yes. Unit weight is the mass for a unit length of the section, so it can be combined with the required member length for quantity estimating. The calculation should use consistent units and should account separately for plates, connections, coatings, and other added items.
Does the sectional area provide the load capacity?
No. Sectional area is one geometric property, not a complete capacity value. Capacity depends on additional section properties, material data, loading, member behavior, connections, and the applicable design method.
Is the DWG ready for fabrication?
The drawing should be treated as a reference resource until its units, geometry, tolerances, and compatibility with the project requirements are verified. Fabrication documents also require member lengths, connections, welds, holes, finishes, and other project-specific information.
