The Hybox 355 SHS 140x140x6 is a square hollow section reference for checking basic dimensions, corner radii, sectional area, unit weight, and the applicable European standard. Use the source data below when coordinating structural steel layouts, quantity takeoffs, or fabrication drawings.
This page is intended as a practical reference alongside related SHS dimensions, hollow section terminology, and structural steel CAD resources. Confirm design resistance, connection behavior, fabrication requirements, and material certification through the governing project documents and a qualified engineer.
Hybox 355 SHS 140x140x6
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 : 140x140x6
Depth : 140 mm
Width : 140 mm
Thickness : 6 mm
Outer Corner Radius : 12 mm
Inner Corner Radius : 6 mm
Sectional Area : 31.2 cm2
Unit Weight : 24.5 kg/m
How to read this SHS reference
The designation 140x140x6 identifies a square hollow section with equal outside depth and width and a stated wall thickness. The listed outer and inner corner radii describe the curved transitions between the flat faces. These radii matter when interpreting section geometry, detailing connections, or comparing CAD geometry with published section data.
Sectional area and unit weight
The sectional area is a cross-sectional property used in engineering calculations and material comparisons. The listed unit weight supports estimating linear material quantities and checking schedules or bills of materials. These values should be taken from the authoritative local table rather than recalculated from nominal dimensions, because corner geometry and product tolerances affect the result.
Understanding the standard reference
The page cites 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. The source also identifies EN 10219-1 as covering technical delivery conditions. Keep these standard roles distinct: dimensional and sectional-property information is not the same as delivery, inspection, or material-certification requirements.
CAD and drafting use
The linked DWG resource can support drafting coordination and preliminary layout work. Before using downloaded geometry for fabrication or design documentation, check the drawing units, layer conventions, revision status, corner representation, and project-specific detailing requirements. A CAD profile should not be treated as a substitute for the governing section table or approved fabrication information.
