SHS 150x150x7 is a cold formed welded square hollow section with equal outside depth and width. This page provides the listed dimensional and mass data, explains the terminology used for square hollow sections, and identifies the applicable European standard reference.
Use the section information together with the project specification, material documentation, connection details, and engineering checks required for the intended application. The downloadable DWG resource can support drafting and coordination workflows, but it should be checked against the project’s current detailing requirements.

Understanding the SHS designation
In the designation SHS 150x150x7, SHS means square hollow section. The two equal first dimensions describe the outside depth and width, while the final dimension identifies the nominal wall thickness. Because the outside dimensions are equal, the section has the characteristic square profile used in structural steel detailing.
What the listed dimensions describe
- Depth and width: These define the overall outside envelope of the square tube.
- Thickness: This describes the nominal wall dimension used to identify the section.
- Corner radii: The outer and inner corner radii describe the rounded transitions between the flat faces. They are important when modeling the profile, checking clearances, and detailing connections.
- Sectional area: This is the listed cross-sectional area of the steel material, rather than the enclosed hollow area.
- Unit weight: This expresses the listed mass per unit length and is useful for estimating member mass, handling requirements, and quantity takeoffs.
Standard and fabrication context
The page refers to EN 10219-2, which addresses dimensions, tolerances, and sectional properties for cold-formed welded structural hollow sections. The related delivery-condition requirements are associated with EN 10219-1. Project documentation should confirm the specified steel grade, manufacturing requirements, inspection requirements, and applicable design rules separately from the section designation.
Using the section in drawings and design work
When this SHS is used in a model or drawing, preserve the corner geometry rather than representing the profile as a sharp-cornered solid unless the simplification is explicitly acceptable for the task. Connection design should account for the hollow profile, available face width, weld access, local detailing, and load transfer. Section properties and resistance checks must be selected and verified by the responsible engineer for the actual loading, restraint, fabrication, and corrosion conditions.
Related reference topics include square hollow sections, rectangular hollow sections, cold formed welded tubes, steel section properties, hollow-section connections, fabrication tolerances, and DWG detailing resources.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow steel profile with equal outside depth and width.
What does the final dimension in SHS 150x150x7 represent?
The final dimension identifies the nominal wall thickness listed for the section.
Why are the corner radii included?
Corner radii define the rounded outside and inside transitions of the tube. They help produce a more accurate CAD representation and support connection, clearance, and fabrication detailing.
What is the difference between sectional area and unit weight?
Sectional area describes the amount of steel in the cross-section. Unit weight describes the listed mass of the section per unit length. They serve different purposes in analysis, estimating, and material takeoffs.
Which standard is referenced for this section?
The page references EN 10219-2 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. Delivery-condition requirements are associated with EN 10219-1.
Is the DWG file ready for every project?
The DWG resource is a drafting aid. Check its profile representation, units, layers, and project-specific detailing requirements before incorporating it into construction or fabrication documents.
