SHS 180x180x5 is a cold-formed welded square hollow section reference for steel detailing, specification review, and preliminary section comparison. This page brings together the source dimensions, corner-radius information, sectional area, unit weight, applicable standard context, and a downloadable DWG file.
Use the dimensional data below when checking a steel shape reference, preparing CAD and DWG details, or reviewing a connection layout. Section selection and structural adequacy still require verification against the governing design criteria, loads, material specification, and connection arrangement.
SHS 180x180x5
Cold Formed Welded Square Steel Tubes
refer to : EN 10219-2
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.

How to read this SHS reference
SHS means square hollow section. The designation identifies a square tube with equal outside depth and width, while the final dimension identifies the wall thickness. The source content also reports the outer and inner corner radii, which are important when modeling the profile accurately or checking how a connected plate, fitting, or weld detail meets the tube wall.
Dimensions and section properties
The listed depth, width, thickness, sectional area, and unit weight describe different aspects of the same profile. Dimensions support layout and clearance checks; sectional area is a cross-sectional property; and unit weight assists with material takeoffs and handling estimates. These values should be read together with the original source block rather than inferred from nominal dimensions alone.
EN 10219-2 context
The page identifies EN 10219-2 as the referenced standard for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections made from non-alloy and fine grain steels. It also notes the relationship with EN 10219-1, which addresses technical delivery conditions. For procurement or design documentation, confirm the complete material and delivery requirements in the project specification.
Drafting and review notes
When creating a model or detail, include the corner geometry instead of representing the section only as a sharp-cornered rectangle. The available DWG resource can support drafting workflows, but the downloaded geometry should be checked against the authoritative dimensions on this page before issue. For related terminology, see the site’s references on structural steel terminology and steel connections and detailing.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It is a hollow steel profile with equal outside depth and width.
What does the 5 in SHS 180x180x5 represent?
In this designation, the final dimension identifies the nominal wall thickness. Refer to the source dimensions on this page for the stated value and other profile data.
Why are the corner radii listed?
Corner radii describe the curved transitions between the flat faces of the tube. They matter for accurate CAD representation, fit-up, clearances, and connection detailing.
What is the relationship between EN 10219-2 and EN 10219-1?
The page associates EN 10219-2 with tolerances, dimensions, and sectional properties, while EN 10219-1 covers technical delivery conditions. Project documentation should identify the applicable requirements clearly.
Is the DWG file a substitute for design verification?
No. A DWG is a drafting reference. Verify its geometry against the source dimensions and have the selected section and connections checked for the actual design situation.
