This page provides a practical reference for the Celsius 355 RHS 300x250x8.8. The existing data identifies the rectangular hollow section’s nominal dimensions, corner radii, sectional area, unit weight, and applicable European standard reference.
Use the profile designation to distinguish this section from other rectangular hollow sections in a steel shape schedule. For design work, confirm the material certificate, project requirements, connection details, and applicable design rules with the responsible engineer.
Celsius 355 RHS 300x250x8.8
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.

Depth : 300 mm
Width : 250 mm
Thickness : 8.8 mm
Outer Corner Radius : 13.2 mm
Inner Corner Radius : 8.8 mm
Sectional Area : 92.9 cm2
Unit Weight : 72.9 kg/m
How to read the RHS designation
RHS means rectangular hollow section. The 300x250x8.8 designation describes the section’s nominal depth, width, and wall thickness, respectively. The source data also lists the outer and inner corner radii, which are important when preparing accurate drawings, checking clearances, or developing connection details.
Reference standard and section data
The page refers to EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. This reference should be read alongside the stated technical delivery requirements and the project’s governing design standard.
The listed sectional area and unit weight are useful for preliminary quantity takeoffs and for locating the relevant section properties in a design workflow. They should not be treated as a substitute for a complete structural verification, including stability, load effects, connections, fabrication, and corrosion requirements.
CAD and drafting use
The downloadable DWG file can support detailing and coordination workflows. Before using it in production drawings, check the drawing units, layer conventions, profile orientation, and whether the geometry reflects the required corner-radius treatment. Related internal references may include RHS dimensions, steel section terminology, connection detailing, and DWG resources.
Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section. It is a closed structural steel profile with a rectangular outside form and hollow interior.
What information is provided for this section?
The source content provides the Celsius 355 designation, nominal dimensions, outer and inner corner radii, sectional area, unit weight, and the EN 10210-2 reference.
Can the DWG file be used directly for structural design?
The DWG is a drafting and coordination resource. Structural design still requires verification of material, loads, stability, connections, fabrication requirements, and the governing project standards.
Why are the corner radii relevant?
Corner radii affect the drawn profile geometry and may influence clearances, connection detailing, fabrication interpretation, and comparisons between section libraries.
