Celsius 355 SHS 180x180x12.5 is a hot-finished square hollow section reference for structural steel detailing and preliminary section review. This page presents the published dimensions, corner radii, sectional area, unit weight, applicable standard reference, and an associated DWG resource.
Use the dimensional data to identify the section in drawings, connection layouts, fabrication documents, and steel-shape schedules. Any final structural application, connection design, or member verification should be completed using the governing project requirements and appropriate engineering checks.

Inner Corner Radius : 12.5 mm
Sectional Area : 82.1 cm2
Unit Weight : 64.4 kg/m
How to read the SHS designation
SHS means square hollow section. The designation 180x180x12.5 identifies the section by its square outside dimensions and wall thickness. For this entry, the listed depth and width are both 180 mm, while the wall thickness is 12.5 mm.
Section dimensions and geometric details
The outside corner radius and inside corner radius describe the rounded transitions between the flat faces of the hollow section. These radii are important when coordinating fabrication details, clearances, weld layouts, connection plates, and CAD geometry. The source lists an outer corner radius of 18.8 mm and an inner corner radius of 12.5 mm.
Sectional area and unit weight
The listed sectional area is 82.1 cm2, and the listed unit weight is 64.4 kg/m. These values help engineers and detailers identify the section consistently across material schedules, takeoffs, and section-property references. They should not be treated as a substitute for project-specific design verification.
Standard reference
The source refers to EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. It also identifies the relationship with EN 10210-1, which addresses technical delivery conditions. Confirm the applicable project edition, material documentation, and specification requirements before relying on the section in procurement or fabrication.
Related detailing considerations
- Coordinate the outside dimensions and corner radii with connection plates, stiffeners, cuts, and access requirements.
- Use the section designation consistently in drawings, bills of material, and revision records.
- Check whether the intended connection detail accounts for the hollow interior and the available face width.
- Review the accompanying DWG as a drafting aid, then verify geometry and project requirements before issuing fabrication information.
