The Hybox 355 SHS 25x25x2 is a square hollow section reference entry for checking section dimensions, corner geometry, sectional area, unit weight, and related CAD information. The values below should be read alongside the stated European standard reference and used as a drafting or preliminary reference rather than as a substitute for project-specific engineering verification.
For readers comparing hollow sections, this page provides a concise example of how an SHS designation identifies the nominal outside dimensions and wall thickness. The accompanying data also helps connect the section designation with the geometric properties used in steel detailing and design workflows.

Hybox 355 Square Hollow Sections
refer to : EN 10219-2:2006-04
the European standard that specifies tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections made of non-alloy and fine grain steels. It complements EN 10219-1, which covers technical delivery conditions.
Dimension : 25x25x2
Depth : 25 mm
Width : 25 mm
Thickness : 2 mm
Outer Corner Radius : 4 mm
Inner Corner Radius : 2 mm
Sectional Area : 1.74 cm2
Unit Weight : 1.4 kg/m
How to read the Hybox 355 SHS designation
SHS means square hollow section. In the designation shown on this page, the section is identified by its square outside dimensions followed by its wall thickness. The source data lists the depth, width, and thickness separately, which is useful when checking a drawing, model, or material schedule.
Section geometry and reference properties
The listed outer and inner corner radii describe the rounded transitions between the flat faces of the hollow section. These details matter when interpreting the actual profile outline, preparing CAD geometry, or comparing nominal dimensions with a manufactured section.
The sectional area and unit weight are provided as reference properties for this specific entry. They should not be inferred from a simplified sharp-corner model, substituted with values from another section, or used without checking the applicable project requirements and design assumptions.
Standard and CAD reference
This entry refers to EN 10219-2:2006-04 for dimensional, tolerance, and sectional-property information associated with cold-formed welded structural hollow sections. The source also distinguishes this reference from EN 10219-1, which addresses technical delivery conditions.
The downloadable DWG can support drafting and layout work. Before incorporating the file into a project model, check units, layer conventions, insertion point, and whether the represented profile matches the intended material schedule.
