How to read the Hybox 355 SHS designation
SHS means square hollow section: a closed steel profile with equal outside width and depth. In this entry, the 100x100x5 designation identifies the listed outside dimensions and wall thickness. The corner radii are reported separately because the corners are rounded rather than perfectly sharp.
Section properties and weight reference
The source content lists the sectional area and unit weight for the profile. Sectional area is commonly used when evaluating material quantity and axial-force-related calculations, while unit weight supports estimating linear mass and handling requirements. These values should be used as a reference from the local table and checked against the governing project requirements before design use.
Applicable standard reference
This profile refers to EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties of cold-formed welded structural hollow sections made from non-alloy and fine grain steels. The source also notes that EN 10219-1 addresses technical delivery conditions. Keep dimensional requirements, delivery requirements, material documentation, and design assumptions distinct when reviewing a section.
CAD and drafting use
The downloadable DWG can support layout and detailing workflows involving this SHS profile. Confirm the drawing unit system, layer conventions, corner representation, and project-specific fabrication requirements before incorporating the file into production documents. A CAD profile is a drafting aid and does not replace connection design, member checks, or fabrication review.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a closed structural steel profile with equal outside width and depth.
What information is provided for Hybox 355 SHS 100x100x5?
The source lists the section dimensions, wall thickness, outer and inner corner radii, sectional area, and unit weight. It also identifies the relevant EN 10219 reference.
Which standard is referenced for this section?
The entry refers to EN 10219-2:2006-04 for tolerances, dimensions, and sectional properties. It separately identifies EN 10219-1 as covering technical delivery conditions.
Is the DWG file suitable for final structural design?
The DWG is intended as a drafting reference. Final structural design and detailing still require verification of loads, connections, tolerances, fabrication requirements, and applicable project standards by the responsible engineer.
