Thickness : 3.6 mm
Sectional Area : 2.64 cm2
Unit Weight : 2.1 kg/m
How to read this CHS reference
CHS means circular hollow section: a round, closed steel profile with a hollow interior. The designation 26.9×3.6 identifies the section using its listed diameter and wall thickness. The page also reports sectional area and unit weight, which are useful when reviewing section-property data and estimating steel quantities.
Standard reference
The source cites EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. It also identifies the relationship with EN 10210-1, which addresses technical delivery conditions. Consult the applicable project specification and current requirements when using standards information for procurement or design.
CAD and drafting use
The downloadable DWG resource can support layout, detailing, and drawing coordination. Check the drawing against the authoritative dimensional data on this page before incorporating it into a project model or fabrication document.
For broader context, related site references on circular hollow sections, steel section properties, EN 10210 terminology, and structural steel CAD/DWG resources can help place this section within a wider design and drafting workflow.
