This page provides a focused reference for the Hybox 355 square hollow section identified as 160x160x4. The listed dimensions, corner radii, sectional area, and unit weight should be read together when reviewing section schedules, preliminary layouts, or fabrication documentation.
Use the dimensional data as a section-identification reference, then confirm project-specific material, connection, fabrication, and design requirements through the applicable project documents and engineering review.
Hybox 355 SHS 160x160x4
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 : 160x160x4
Depth : 160 mm
Width : 160 mm
Thickness : 4 mm
Outer Corner Radius : 8 mm
Inner Corner Radius : 4 mm
Sectional Area : 24.5 cm2
Unit Weight : 19.2 kg/m
How to read the Hybox 355 SHS designation
The SHS designation means square hollow section. In this reference, 160x160x4 identifies the nominal outside depth, outside width, and wall thickness. The corner radii are listed separately because the section profile is formed with rounded corners rather than sharp external and internal corners.
Understanding the listed section data
- Depth and width: These describe the nominal outside dimensions of the square profile.
- Thickness: This identifies the wall dimension used to distinguish this section from other sizes in the same series.
- Corner radii: The outer and inner radius entries describe the rounded transition at each corner and are relevant when checking clearances, detailing, and profile geometry.
- Sectional area: This is a geometric property of the cross-section and is commonly used with other section properties during engineering calculations.
- Unit weight: This supports estimating member dead load, handling requirements, and material quantities. It should not be treated as a substitute for project-specific mass or fabrication verification.
Standard reference and design use
The page identifies EN 10219-2:2006-04 for dimensional, tolerance, and sectional-property reference, while the accompanying description distinguishes the technical delivery conditions covered by EN 10219-1. When using this section in a design or drawing, review the complete project specification, material documentation, manufacturing requirements, and connection details rather than relying on the section designation alone.
For related learning, see the site’s references on structural hollow sections, steel section properties, steel tolerances, and connection detailing. These topics help connect the tabulated geometry with drafting and engineering checks.

Frequently asked questions
What does SHS mean?
SHS means square hollow section. It describes a hollow steel profile with a square outside form and rounded corners.
What does 160x160x4 identify?
It identifies the nominal outside depth, nominal outside width, and wall thickness listed for this Hybox 355 section.
Why are the corner radii listed separately?
The corner radii define the rounded geometry at the section corners. They can matter when checking profile clearances, preparing connection details, or using the section in CAD.
What is the difference between EN 10219-1 and EN 10219-2 in this reference?
The page describes EN 10219-2 as the reference for dimensions, tolerances, and sectional properties, and identifies EN 10219-1 with technical delivery conditions. Confirm the applicable requirements for the project and supplied material.
Can the DWG file be used directly for fabrication?
The DWG is a CAD reference file. Review its units and geometry, then coordinate any fabrication or issued-for-construction use with the project drawing standards and responsible engineer.
