The Hybox 355 SHS 350x350x8 is a square hollow section reference for engineers, detailers, fabricators, and CAD users working with structural steel profiles. This page brings together the source dimensions, corner radii, sectional area, unit weight, applicable standard reference, and a downloadable DWG resource.
Use the dimensional data for identification and drafting reference, then verify design assumptions against the governing project requirements and the applicable material and fabrication documentation. For broader terminology, see the related references on square hollow sections, sectional properties, and structural steel connections.

Hybox 355 SHS 350x350x8 reference
SHS means square hollow section: a closed structural steel profile with equal outside depth and width. The listed section has a depth and width of 350 mm, with an 8 mm wall thickness. Its outer and inner corner radii are included because corners affect detailing, fit-up, and how the section is represented in drawings.
Standard and product data
The source identifies EN 10219-2:2006-04 as the dimensional and sectional-property reference for 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. Keep the standard reference alongside the section data when preparing specifications or checking fabrication documentation.
The listed sectional area is 107 cm2, and the listed unit weight is 84 kg/m. These values are useful for reference, quantity takeoffs, and preliminary coordination, but project-specific design checks should use the governing design basis and verified material documentation.
CAD and drafting resource
The supplied DWG download can support detailing and CAD coordination for this profile. Check the drawing units, insertion orientation, layer conventions, and project drafting standards before incorporating the file into production drawings. Related internal resources may include the structural steel DWG library, steel section dimensions, and connection detailing guides.
