SHS 180x180x7 is a cold-formed welded square hollow section listed with its principal dimensions, corner radii, sectional area, and unit weight. This page provides a concise reference for engineers, detailers, estimators, and CAD users working with structural steel hollow sections.
Use the source data below as the dimensional reference for this section. For broader terminology, compare the related SHS and RHS steel section guides, and review the page on structural steel section properties when you need context for area, weight, and design calculations.
SHS 180x180x7
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.

Depth : 180 mm
Width : 180 mm

Unit Weight : 36.7 kg/m
How to read the SHS 180x180x7 designation
The designation identifies a square hollow section with a nominal depth and width of 180 mm and a wall thickness of 7 mm. Because the section is square, its listed depth and width are the same. The corner radii are reported separately because the outside and inside corners are rounded rather than sharp.
Reference values and standard context
The source entry reports the outer corner radius, inner corner radius, sectional area, and unit weight alongside the basic dimensions. Sectional area is useful when reviewing section-property data, while unit weight supports quantity checks and material takeoffs. These values should be kept distinct from resistance, stability, connection, and serviceability checks, which require an appropriate engineering design procedure.
The entry refers to EN 10219-2 for dimensional and sectional-property information and identifies its relationship with EN 10219-1, which addresses technical delivery conditions. Consult the applicable project specification and the complete standard documents when tolerances, material requirements, inspection, or acceptance criteria matter.
CAD and drafting reference
The downloadable DWG resource can help users place the SHS profile in drawings and preliminary detailing workflows. Verify units, layer conventions, insertion scale, and the intended representation of the corner geometry before using the file in a project deliverable. A CAD profile is a drafting reference; it does not by itself establish design capacity or connection adequacy.

Frequently asked questions
What does SHS 180x180x7 mean?
It identifies a square hollow section with a listed depth of 180 mm, width of 180 mm, and wall thickness of 7 mm.
Which standard is referenced for this section?
The source entry refers to EN 10219-2 for dimensional and sectional-property information and notes its relationship with EN 10219-1 for technical delivery conditions.
What corner information is provided?
The reference lists both an outer corner radius and an inner corner radius. These values describe the rounded tube corners and are relevant when checking geometry or preparing detailed drawings.
Does the listed unit weight determine the design capacity?
No. Unit weight supports estimating and material takeoffs, but it does not establish axial, bending, buckling, connection, or other design resistance.
Is a DWG file available?
Yes. The source includes a DWG download for the SHS 180x180x7 profile. Confirm the file units and drawing conventions before incorporating it into project documentation.
