This reference entry identifies the Celsius 355 circular hollow section (CHS) with a 355.6 mm diameter and 14.2 mm wall thickness. Use the source values below for preliminary section identification, drafting, and coordination, while design verification remains dependent on the applicable project requirements and engineering checks.
The page also provides context for EN 10210-2 and a downloadable DWG resource. For related guidance, compare this entry with the site’s references on circular hollow sections, sectional properties, and steel connection detailing.
Celsius 355 CHS 355.6×14.2
Celsius 355 Circular Hollow Sections
refer to : EN 10210-2:2006-04
the European standard that specifies tolerances, dimensions, and sectional properties for hot-finished structural hollow sections of non-alloy and fine grain steels. It supports EN 10210-1, which covers technical delivery conditions.
Diameter : 355.6 mm
Thickness : 14.2 mm
Sectional Area : 152 cm2
Unit Weight : 119.3 kg/m
How to read this CHS reference
A circular hollow section is a closed steel profile with a round outside form. Its diameter and wall thickness define the basic section designation, while the sectional area and unit weight help identify the profile in material schedules, design references, and drafting workflows.
Section identification
- Diameter: The listed outside diameter is 355.6 mm.
- Thickness: The listed wall thickness is 14.2 mm.
- Sectional area: The source lists 152 cm2. This property is used with material and design data when evaluating the steel section.
- Unit weight: The source lists 119.3 kg/m. This is useful for quantity takeoffs, shipping estimates, and checking member schedules, but it should not be treated as a complete structural design result.
Standard reference
The entry refers to EN 10210-2:2006-04 for dimensional tolerances, dimensions, and sectional properties of hot-finished structural hollow sections. The source also identifies its relationship with EN 10210-1, which addresses technical delivery conditions. Confirm the project-specified edition, material requirements, tolerances, and fabrication documentation before using the profile in procurement or design work.
Using the DWG file
The linked DWG is a drafting reference for the named Celsius 355 CHS profile. Review units, insertion scale, layer conventions, and drawing orientation after download. A CAD outline does not by itself confirm fabrication tolerances, connection behavior, local stability, corrosion allowance, or design resistance.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section, a round, closed structural steel profile.
What are the listed dimensions for Celsius 355 CHS 355.6×14.2?
The source lists a diameter of 355.6 mm and a wall thickness of 14.2 mm.
What sectional area and unit weight are listed?
The listed sectional area is 152 cm2, and the listed unit weight is 119.3 kg/m.
Which standard is referenced?
The entry refers to EN 10210-2:2006-04 and notes its connection with EN 10210-1. Check the project documentation and current governing requirements before relying on a standard reference for procurement or design.
Is the DWG file sufficient for structural design?
No. The DWG should be treated as a drafting and coordination resource. Structural design requires verification of the applicable material, geometry, tolerances, loading, connections, and governing design requirements.
