Celsius 355 RHS 300x250x10
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 : 300x250x10
Depth : 300 mm
Width : 250 mm
Thickness : 10 mm
Outer Corner Radius : 15 mm
Inner Corner Radius : 10 mm
Sectional Area : 105 cm2
Unit Weight : 82.4 kg/m
How to read the RHS designation
The designation 300x250x10 describes the nominal section dimensions: depth, width, and wall thickness. The source data lists these as 300 mm depth, 250 mm width, and 10 mm thickness. Because an RHS has rounded corners, the listed outer and inner corner radii are also important when the profile is modeled, dimensioned, or checked against a detail.
Section properties and reference standard
The source lists a sectional area of 105 cm2 and a unit weight of 82.4 kg/m. These values support quantity takeoffs, member identification, and preliminary reference work, but engineering design should use the governing project requirements and verified design calculations.
The page refers to EN 10210-2:2006-04, which covers dimensions, tolerances, and sectional properties for hot-finished structural hollow sections. It also identifies the relationship to EN 10210-1, which addresses technical delivery conditions. Readers comparing profiles may benefit from internal references covering hollow-section standards, steel section properties, dimensional tolerances, and designations.

Frequently asked questions
What does RHS mean?
RHS means rectangular hollow section. It is a hollow steel profile with a rectangular outside form and rounded corners.
What do the dimensions 300x250x10 represent?
For this reference, the designation corresponds to a 300 mm depth, 250 mm width, and 10 mm wall thickness.
Which standard is referenced for this section?
The source refers to EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties, and identifies EN 10210-1 as the standard covering technical delivery conditions.
What section data is listed?
The reference lists the outer corner radius, inner corner radius, sectional area, and unit weight in addition to the main dimensions.
Is a DWG file available?
Yes. The page includes a DWG download for the Celsius 355 RHS 300x250x10 profile. Confirm units and geometry before incorporating it into a project drawing.
Can the listed properties replace design verification?
No. The values are reference data for the identified section. Structural applications require project-specific checks, applicable design rules, connection review, and confirmation that the selected profile matches the design documents.
