Kutu Profiller
As FINDIKSAN BORU, we supply all types of hollow sections as steel structural elements with closed geometric cross-sections, widely used in the construction and manufacturing sectors, manufactured to meet customer requirements.
Cross-Section Types
Based on the production method and cross-section geometry, they are divided into two main groups:
- Square Hollow Sections
- Rectangular Hollow Sections
Production Varieties and Material Types
Hollow sections are manufactured from different material types according to the corrosion resistance and strength requirements of the application area:
| Type | Description | Application Areas |
|---|---|---|
| Black Profile (HR) | Produced from hot-rolled sheet. Thick-walled and high-strength. | Heavy industrial structures, load-bearing constructions |
| DKP Profile (CR) | Produced from cold-rolled sheet. Smooth surface, thin-walled. | Furniture, decoration, interior applications suitable for painting |
| Galvanized Profile | Produced from zinc-coated sheet for corrosion resistance. | Exterior structures, steel constructions, landscaping |
Production Standards and Quality Classes
Square and rectangular profiles offered by Fındıksan Boru are manufactured in accordance with the following standards:
- DIN 2395
- TS 5317
- TS EN 10219-2
- TS EN 10305-5
Quality classes used as standard in production:
- DC01 (DIN EN 10130)
- S185, S235JRH / J0H / J2H
- S275J0H / J2H
- S355J0H / J2H (DIN EN 10025)
Production Technology
Square and rectangular hollow sections are manufactured from pickled (acid-cleaned) or cold-rolled steel strips using high-frequency welding (ERW – Electric Resistance Welding) technology on advanced production lines. This method ensures homogeneous weld quality and high dimensional precision.
