How to read this CHS reference
A circular hollow section is a closed, round steel profile. Its diameter and wall thickness describe the basic geometry, while sectional area and unit weight help identify the profile in estimating, modeling, detailing, and design documentation.
- Diameter: the reported outside diameter of the circular section.
- Thickness: the reported wall thickness.
- Sectional area: the cross-sectional steel area listed for the profile.
- Unit weight: the listed mass per unit length, useful for material takeoffs and coordination.
Standard and drafting context
The source refers to EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties of hot-finished structural hollow sections. The standard reference should be read with the applicable technical delivery requirements and project specifications.
The downloadable DWG can support CAD layouts, steel detailing, and preliminary model coordination. Confirm the section designation, units, material requirements, end conditions, and connection assumptions before using the profile in a fabrication or structural design package.
Related SteelSTD references
