How to read the Hybox 355 SHS designation
SHS means square hollow section: a closed steel profile with equal outside width and depth. The designation shown on this page communicates the section family and its stated size and wall thickness. The dimensional fields below the designation provide the individual values needed for drawings, schedules, and section-property checks.
Dimensions and corner radii
The page reports the outside depth and width together with the wall thickness. It also identifies separate outer and inner corner radii. These radius values matter when preparing accurate CAD geometry, checking clearances, detailing connected plates, or comparing a model with a manufacturer or project section library.
Sectional area and unit weight
The listed sectional area is useful when reviewing section-property data and carrying out material takeoffs. The unit weight supports preliminary mass estimates and can help coordinate handling, fabrication, and shipping information. These values should be used consistently with the project specification and verified before they are used for final procurement or design decisions.
Standard reference and technical scope
The source refers to EN 10219-2:2006-04 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections made from non-alloy and fine grain steels. It also notes the relationship with EN 10219-1, which addresses technical delivery conditions. The standard reference provides context for interpreting the listed section data; it does not replace the project specification or the engineer’s design checks.
CAD and drafting workflow
The downloadable DWG can support layout, detailing, and coordination tasks where a square hollow section profile is needed. Check the drawing units, insertion scale, layer conventions, and model orientation before incorporating the file into a project document. A useful related resource on this site would be the CAD/DWG reference library, along with guides to SHS terminology, section properties, and steel connection detailing.
