Open Section Type C

Open cross-sections type C 140, C 180, C 210
The standard cold-rolled thin-walled cross-sections, type C, are produced based on the company’s high quality criteria, covering a wide range of applications. They are produced in desired lengths up to 14m depending on the requirements of the project. It is possible to drill holes Φ6, Φ8, Φ10, Φ12.5, Φ14, Φ16, Φ18, Φ20, Φ22 at any point with excellent precision for the application of screw connections with other metal and structural elements.

Open C-sections are usually used as purlins or purlins to support the siding or building envelope. Obviously, the number of applications of these cross-sections is unlimited, provided that the static study of the structure has been prepared.

Open cross-sections type C40x40 & type C20x40
Alternatively, there is the possibility of producing standardized cold-rolled thin-walled cross-sections, type C40x40 & type C20x40. They are produced with steel sheets of high quality and resistance, with hot galvanic protection. The thickness of the plates ranges from 2.00mm to 3.00mm in lengths shorter than 8 meters.

Sheets

They are mainly produced with high-quality and durable steel sheets, with hot galvanic protection, according to EN 10346, EN 10143 standards in terms of quality and tolerances. The thickness of the plates ranges from 1.50mm to 3.00mm. Galvanized steel sheets of 2.00mm thickness are usually used.

high strength steel sheets from DX51D up to S350GD
hot-dip galvanizing Z 70 ~ 275 gr/m²
or with aluzinc protection AZ 70 ~ 265 gr/m²

Open C-section

	C 140	C 180	C 210
Nominal sheet thickness [mm]	Weight per unit length [kg/m] *
1,50	3,40	3,80	4,20
2,00	4,50	5,10	5,60
2,50	5,60	6,40	7,00
3,00	6,70	7,70	8,40

* The weight per unit length was calculated considering the specific gravity of steel = 7850 kg/m³.

Thin-walled C-type open sections are attached to the load-bearing body by the standard method of bolting. It is recommended that the support is done with screws and not with self-drilling screws or rivets. In general, in thin-walled cross-sections, welding connection is not preferred.

Thin-walled C-sections cannot be overlapped. U or L cross-section connectors with screw connection are used to connect the pieces. The thickness of the link plate is always greater than that of the cross-section, while their length depends on the opening between the supports. It is recommended that the connections be made at the locations of the supports (columns, beams).

For structural constructions, the reduction in strength due to notches must be calculated taking into account what is provided by the ΕΝ 1993-1-3 standard.
