How to read this SHS reference
The designation 40x40x2.5 identifies the listed overall depth, overall width, and wall thickness. Because the depth and width are equal, the profile is presented as a square hollow section. The corner radii are listed separately because the outside and inside corners affect the actual section shape and should be represented correctly in drawings and calculations.
Standard reference and delivery data
This page identifies EN 10219-2:2006-04 as the reference for tolerances, dimensions, and sectional properties for cold-formed welded structural hollow sections made from non-alloy and fine grain steels. The source also notes that EN 10219-1 covers technical delivery conditions. Check the applicable project requirements and governing design documentation before using any tabulated value.
Using the CAD download
The accompanying DWG file can support drafting and coordination workflows. Verify the profile orientation, units, layer conventions, and drawing scale after importing the file into your CAD system. A CAD outline should not be treated as a substitute for the authoritative dimensional and design data.
Design-use reminder
The listed sectional area and unit weight are reference values for this profile. Member resistance, stability, connection behavior, fabrication requirements, and project suitability require separate engineering verification based on the governing design conditions.
Frequently asked questions
What does 40x40x2.5 mean?
It identifies the listed overall depth, overall width, and wall thickness of the square hollow section: 40 mm depth, 40 mm width, and 2.5 mm thickness.
Which standard is referenced for this section?
The source references EN 10219-2:2006-04 for the listed tolerances, dimensions, and sectional properties. It also identifies EN 10219-1 as covering technical delivery conditions.
What are the corner radii?
The listed outer corner radius is 5 mm, and the listed inner corner radius is 2.5 mm. These values describe the rounded corners rather than a sharp-cornered square.
Is a DWG file available?
Yes. The page includes a DWG download for Hybox 355 SHS 40x40x2.5. Confirm units and drawing settings when opening or importing the file.
Can the listed values be used directly for structural design?
They are reference data for the identified section. Structural design also requires verification of the member, loading, stability, connections, material requirements, and applicable project rules.
