Hybox 355 SHS 150x150x8
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.
Dimension : 150x150x8
Depth : 150 mm
Width : 150 mm
Thickness : 8 mm
Outer Corner Radius : 20 mm
Inner Corner Radius : 12 mm
Sectional Area : 43.2 cm2
Unit Weight : 33.9 kg/m
How to read the section designation
The designation 150x150x8 describes a square hollow section with equal outside depth and width and a stated wall thickness. The page separately lists these values so they can be checked against drawings, schedules, and section-property references.
Corner radii and section data
Unlike a sharp-cornered square, a cold-formed welded hollow section has rounded outside and inside corners. The listed outer and inner corner radii help describe the section geometry and should be considered when interpreting fabrication details or comparing CAD geometry with the reference dimensions.
The sectional area and unit weight are reference properties for this listed section. They should be used as published local data and verified against the applicable project documents before they are used in material takeoffs, connection detailing, or engineering calculations.
Standard reference and CAD resource
The source refers to EN 10219-2:2006-04 for dimensions, tolerances, and sectional properties of cold-formed welded structural hollow sections. It also identifies EN 10219-1 as covering technical delivery conditions. The linked DWG file can support drafting, but users should confirm the drawing units, geometry, and project-specific requirements before issuing design documentation.
