SHS 125x125x10 is a cold-formed welded square structural hollow section. This reference page brings together the listed profile dimensions, corner radii, sectional area, unit weight, applicable standard context, and the existing CAD drawing resource.
The designation identifies a square section with equal outside depth and width and a stated wall thickness. For drafting or specification work, review the complete dimensional data rather than treating the designation alone as a fabrication description.
SHS 125x125x10
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 : 125 mm
Width : 125 mm
Thickness : 10 mm
Outer Corner Radius : 25 mm
Inner Corner Radius : 15 mm
Sectional Area : 42.57 cm2
Unit Weight : 33.4 kg/m
Understanding the SHS designation
SHS means square hollow section. In United States terminology, a similar product category is commonly called square HSS. These terms describe related section forms, but designations from different standards should not be assumed to be interchangeable. Confirm the governing product standard, material requirements, tolerances, and availability before specifying a section.
How to interpret the listed properties
The equal depth and width describe the outside square envelope, while the thickness identifies the listed wall thickness. The outer and inner corner radii define the rounded corner geometry created by the forming process. Those radii matter when preparing accurate section views, checking clearances, or coordinating attached plates and weld details.
Sectional area represents the amount of steel in the cross section and is used in several engineering calculations. Unit weight expresses mass per unit length and can support material takeoffs by multiplying the listed value by the required member length. Allowances for connections, cutting, coatings, fabrication, and waste require separate consideration.
Standard context
The source identifies EN 10219-2 for the dimensional and sectional-property context of this cold-formed welded hollow section. Its dimensional information works together with the associated technical delivery requirements. Users working primarily with United States specifications should verify whether the referenced European designation is acceptable for the project rather than substituting it directly for a domestic HSS designation.
Using the CAD drawing
The existing DWG resource can assist with profile layouts, section details, member diagrams, and drafting coordination. Before incorporating it into a drawing set, confirm the file units, outside dimensions, wall thickness, corner radii, insertion point, layer organization, and drawing scale against the listed reference data.
A section-profile drawing does not establish connection capacity, member strength, material grade, weld requirements, or code compliance. Those items depend on the project design criteria and require engineering verification.

Frequently asked questions
What does SHS 125x125x10 mean?
SHS identifies a square hollow section. The listed designation corresponds to equal outside depth and width of 125 mm with a listed thickness of 10 mm.
What are the listed corner radii?
The source data gives an outer corner radius of 25 mm and an inner corner radius of 15 mm. These rounded corners should be retained when accurate profile geometry or local clearances are important.
What is the listed unit weight?
The published source content lists a unit weight of 33.4 kg/m. It can be used as a reference for length-based material estimates, subject to project-specific fabrication and procurement allowances.
What is the listed sectional area?
The listed sectional area is 42.57 cm². Sectional area is a geometric property and should not be interpreted by itself as a load capacity.
Can the DWG be used directly in a project drawing?
Use it as a drafting reference only after checking its geometry, units, layers, and scale. Project suitability, connection design, material requirements, and structural performance must be verified separately.
Is SHS the same as square HSS?
Both terms refer to square structural hollow-section forms, but they may belong to different standards and designation systems. Similar outside geometry does not establish equivalent tolerances, materials, properties, or compliance.
