This page provides a focused reference for SHS 150x150x4, identified in the source data as a cold-formed welded square steel tube. The existing section below records its principal dimensions, corner radii, sectional area, unit weight, standards context, and DWG resource.
Use the listed information to confirm the profile identity before placing it in a drawing, model, material schedule, or preliminary quantity takeoff. Final specification and structural use should always be checked against the governing project documents and applicable standard requirements.
SHS 150x150x4
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.
Dimension : 150x150x4
Depth : 150 mm
Width : 150 mm
Thickness : 4 mm
Outer Corner Radius : 8 mm
Inner Corner Radius : 4 mm
Sectional Area : 22.95 cm2
Unit Weight : 18 kg/m
How to Read the SHS Designation
SHS means square hollow section. In the designation SHS 150x150x4, the first two values correspond to the listed outside depth and width, while the final value identifies the listed wall thickness. Because the depth and width are equal, the cross-section is square.
Understanding the Listed Geometry
A formed square tube does not have perfectly sharp corners. The outer and inner corner radii describe the curved geometry created at each corner. These radii are relevant when preparing close-fitting plates, connection components, section cuts, and fabrication details. A CAD representation should retain the rounded profile rather than replacing it with four sharp-cornered lines.
Sectional Area and Unit Weight
The sectional area describes the amount of steel contained in the cross-section. Unit weight expresses the listed mass for a unit length of the member. These properties support material schedules, takeoffs, and engineering calculations, but they do not state the section’s load capacity.
Structural resistance also depends on factors such as material grade, member length, restraint, loading direction, local behavior, connection design, and the applicable design rules. The values on this page should therefore be treated as reference inputs rather than a complete design check.
EN 10219-2 Context
The source associates this section with EN 10219-2, which addresses tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections. It works alongside EN 10219-1, which addresses technical delivery conditions. Project specifications should be reviewed to confirm which requirements and documentation apply.
Using the DWG Resource
- Verify the profile: Compare the drawing geometry with the dimensions and radii shown in the preserved source content.
- Check drawing units: Confirm the CAD file units before scaling, inserting, or measuring the section.
- Inspect layers and linework: Review object types, layer naming, duplicate geometry, and closed boundaries before reuse.
- Coordinate connections: Account for rounded corners when detailing plates, weld access, bolts, caps, and adjoining members.
- Retain project controls: Apply the required CAD standards, title-block information, revision process, and professional review.

Frequently Asked Questions
What type of steel section is SHS 150x150x4?
The source identifies it as a cold-formed welded square steel tube. Its equal listed depth and width create the square external form associated with an SHS designation.
Why are inner and outer corner radii listed?
They define the curved corner geometry on the outside and inside of the hollow section. This information is useful when checking clearances, preparing section views, and detailing components that approach the corners.
Does unit weight provide the total member weight?
Unit weight is stated per unit length. A takeoff must also consider the actual member length and any project-specific items such as cuts, plates, fittings, or connection material.
Does sectional area indicate load capacity?
No. Sectional area is one geometric property used in analysis and design. Capacity cannot be established from area alone because material, stability, loading, connections, and design-code requirements must also be considered.
Can the DWG be inserted directly into a project drawing?
It should first be checked for units, scale, geometry, layers, and compatibility with the project’s CAD standards. The section and its connections must also be verified for the intended application by the responsible technical professional.
