How to read this SHS reference
SHS means square hollow section. Its outside profile is square, while the hollow interior reduces material in the middle of the section and leaves steel distributed around the walls and corners. The listed depth and width describe the external profile, while thickness describes the wall dimension.
The outer and inner corner radii describe the curved transitions between the flat faces. These radii matter when checking clearances, preparing connection details, interpreting CAD geometry, or comparing the section with other hollow-section profiles.
Section properties and detailing context
The sectional area is used in calculations involving the amount of steel in the cross-section. The unit weight expresses the listed mass per unit length and can support material takeoffs, handling reviews, and preliminary quantity checks. Confirm the governing design assumptions before using either property in a project calculation.
The page identifies EN 10210-2:2006-04 as the dimensional and sectional-property reference for this hot-finished structural hollow section. It also points to the related technical delivery requirements covered by EN 10210-1. Treat the standard reference as part of the section’s identification and verify the required material documentation for the project.
CAD and drawing coordination
The available DWG file can assist with drafting, layout coordination, and connection detailing. Check the drawing units, layer conventions, insertion point, and project-specific drafting standards before incorporating the geometry into production documents. Related SteelSTD resources on SHS terminology, hollow-section properties, steel connections, and CAD detailing can help place this section in a broader workflow.
Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow structural steel profile with a square external shape.
What standard is referenced for this section?
The source identifies EN 10210-2:2006-04 for dimensions, tolerances, and sectional properties, with EN 10210-1 associated with technical delivery conditions.
Why are both outer and inner corner radii listed?
The two radii describe the curved corner geometry on the outside and inside of the hollow section. They are useful when coordinating accurate CAD geometry and connection or clearance details.
What is the purpose of the sectional area value?
Sectional area describes the amount of steel contained in the cross-section. Engineers may use it with the applicable design method and material assumptions when evaluating a member.
What does unit weight mean on this page?
Unit weight identifies the mass associated with a unit length of the section. It is useful for material quantity checks and handling coordination, subject to project verification.
Is the DWG file ready for construction documents?
The DWG is a drafting resource. Review its units, geometry, layer setup, and project-specific requirements before using it in issued drawings.
