The Hybox 355 SHS 160x160x5 is a square hollow structural section reference for engineers, detailers, fabricators, and CAD users. This page presents the source dimensions and section data together with practical context for interpreting the profile and using its downloadable DWG resource.
Use the labeled values below as the controlling local reference for this section. Before specifying the profile in a project, confirm the required material grade, design checks, connection details, fabrication requirements, and applicable project specifications.
Hybox 355 SHS 160x160x5
Hybox 355 Square Hollow Sections
refer to : EN 10219-2:2006-04
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.

Width : 160 mm
Thickness : 5 mm
Outer Corner Radius : 10 mm
Inner Corner Radius : 5 mm
Sectional Area : 30.4 cm2
Unit Weight : 23.9 kg/m
How to read the SHS designation
SHS means square hollow section. In the designation 160x160x5, the first two dimensions identify the nominal outside depth and width, while the final dimension identifies the wall thickness. The source data also lists the outer and inner corner radii, which are important when modeling the profile accurately or checking clearances at connections.
Using the section properties
The sectional area is useful for understanding the amount of steel in the cross-section and for calculations that depend on area. The listed unit weight supports material takeoffs, shipping estimates, and preliminary weight checks. These values should be used with the project’s governing design method and verified against the applicable material and fabrication requirements.
EN 10219-2 reference
The page identifies EN 10219-2:2006-04 as the dimensional and sectional-property reference for the listed cold-formed welded hollow section information. It also distinguishes this reference from EN 10219-1, which addresses technical delivery conditions. Readers comparing profiles should review both the dimensional data and the relevant procurement requirements rather than relying on the designation alone.
CAD and detailing workflow
The downloadable DWG can help users begin a CAD detail, section library, or layout based on the profile. Model the outside dimensions, wall thickness, and corner radii as shown in the source data. For fabrication drawings, coordinate the section with connection plates, welds, bolts, access requirements, and any required steel connection detailing guidance. The DWG is a drafting reference and does not replace engineering review.
Frequently asked questions
What does SHS mean?
SHS means square hollow section, a structural steel profile with a square outside form and a hollow interior.
What does 160x160x5 describe?
For this page, the designation identifies the listed nominal outside depth, nominal outside width, and wall thickness. The source content provides the corresponding values in millimeters.
Why are the corner radii listed?
Corner radii affect the actual modeled shape of the section and can matter when checking clearances, fitting connection components, or preparing accurate CAD details.
What information is provided for weight and material takeoff?
The source lists the section’s unit weight. Use it for preliminary takeoffs and weight checks, then confirm the final quantity using the project bill of materials and fabrication data.
Is the DWG ready for structural design?
The DWG is provided as a drafting reference. Structural design still requires verification of loads, restraints, connections, material requirements, fabrication tolerances, and the governing design standard.
