The Celsius 355 CHS 244.5×5.6 is a hot-finished circular hollow section reference for structural steel detailing and preliminary section comparison. This page records the source dimensions and properties for the section without replacing the authoritative local data.
Use the reference values below alongside related resources on circular hollow sections, sectional properties, and structural steel terminology when reviewing a design or preparing drawings.
Celsius 355 CHS 244.5×5.6
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 : 244.5 mm
Thickness : 5.6 mm
Sectional Area : 42 cm2
Unit Weight : 33 kg/m
Understanding the Celsius 355 CHS reference
A circular hollow section, or CHS, has a circular outside profile and a hollow interior. Its diameter and wall thickness describe the basic geometry, while the sectional area and unit weight help identify the amount of steel in the section and its mass per unit length.
Dimensions and listed properties
The listed diameter is 244.5 mm, and the listed thickness is 5.6 mm. The source gives a sectional area of 42 cm2 and a unit weight of 33 kg/m. These values should be read directly from the local reference data when checking schedules, estimates, or drawing information.
Standard reference and drafting use
The page identifies EN 10210-2:2006-04 as the dimensional and sectional-property reference for the Celsius 355 circular hollow section entry. The accompanying DWG resource can support CAD coordination and detailing, but drawings and design documents should still be checked against the project specification and verified by the responsible engineer.
For broader comparison, useful related topics include CHS versus RHS and SHS sections, steel section designations, and CAD blocks for structural steel.
Frequently asked questions
What does CHS mean?
CHS means circular hollow section. It describes a hollow structural steel profile with a circular cross-section.
What are the listed dimensions of this section?
The source lists a diameter of 244.5 mm and a thickness of 5.6 mm.
What sectional area and unit weight are listed?
The listed sectional area is 42 cm2, and the listed unit weight is 33 kg/m.
Which standard is referenced?
The entry refers to EN 10210-2:2006-04 for the dimensions, tolerances, and sectional properties of the referenced hot-finished structural hollow section.
Is the DWG file suitable for final structural design?
The DWG is a drafting and coordination resource. It should not be treated as a substitute for project-specific engineering checks, design calculations, or drawing review.
