Celsius 355 RHS 150x100x10 is a rectangular hollow section reference for structural steelwork, detailing, and drafting. The existing data identifies its nominal dimensions, corner radii, sectional area, and unit weight.
This page also places the section in the context of hot-finished hollow-section terminology and the cited European standard. Use the values below as a reference when reviewing drawings, schedules, connection details, or CAD resources; design use still requires project-specific verification by a qualified engineer.
Celsius 355 RHS 150x100x10
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 : 150x100x10
Depth : 150 mm
Width : 100 mm
Thickness : 10 mm
Outer Corner Radius : 15 mm
Inner Corner Radius : 10 mm
Sectional Area : 44.9 cm2
Unit Weight : 35.2 kg/m
Understanding the RHS designation
RHS means rectangular hollow section. The designation describes a closed rectangular steel profile, while the dimension notation identifies the outside depth, outside width, and wall thickness. The section’s closed shape can be relevant when comparing it with open structural sections, particularly for drafting and connection-layout discussions.
What the listed properties mean
The depth, width, thickness, and corner radii describe the section geometry. Corner radii are important when preparing accurate fabrication details, checking clearances, or coordinating the profile with plates, bolts, welds, and adjoining members.
Sectional area describes the amount of steel in the cross-section, while unit weight is a mass-per-length reference used in material estimates and steel schedules. These entries do not by themselves establish resistance, allowable loading, buckling performance, connection capacity, or suitability for a particular structure.
Standard and drafting context
The source cites EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections, with EN 10210-1 identified as covering technical delivery conditions. The cited standard context is useful when checking terminology, dimensional conventions, and procurement documentation.
The accompanying DWG resource can support drawing coordination and CAD workflows. Before using any downloaded geometry for fabrication, compare it with the project specification, approved drawings, and the controlling material and manufacturing requirements.

Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section, a closed structural steel profile with a rectangular outside shape.
What does 150x100x10 identify?
It identifies the nominal outside depth, nominal outside width, and wall thickness listed in the reference. The source also provides the associated corner radii.
What standard is cited for this section?
The source cites EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties, and identifies EN 10210-1 as covering technical delivery conditions.
Can the listed unit weight be used as a design capacity?
No. Unit weight is a mass-per-length reference. Structural resistance, stability, connection capacity, and project suitability require separate engineering checks and applicable project requirements.
What should be checked before using the DWG file?
Check the CAD geometry against the project specification, approved drawings, fabrication requirements, and the applicable section data before using it for detailing or manufacture.
