Discover our highly requested industrial black steel pipes engineered to comply with European, ASTM, and Turkish national structural standards.
Turkey occupies a vital geographic and industrial hub bridging Europe, the Middle East, and Central Asia. The country's construction sector, driven by major urban renewal initiatives, massive infrastructure upgrades (such as high-speed rail links and expanding transit ports), and a robust manufacturing sector, demands exceptionally high volumes of carbon steel products. Black steel pipes, primarily known for their high tensile strength and versatile applications, serve as the backbone for these projects.
Furthermore, because Turkey is situated on highly active seismic zones, the structural specifications for building supports, deep foundation piles, and plumbing infrastructure are uniquely stringent. Structural steel must provide superior ductility, uniform thickness, and reliable weldability. This is where high-quality black ERW (Electric Resistance Welded) and SSAW (Spiral Submerged Arc Welded) steel pipes play a decisive role.
We bridge the gap between high-volume requirements and localized industrial standards with unmatched supply chain capabilities.
Established in 1998, our 70,000 m² production facility is situated just 40 kilometers from China's primary northern port, XinGang. This proximity reduces domestic transit times and guarantees competitive freight costs for direct shipping lines to Istanbul, Izmir, and Mersin.
Operating under ISO9001 quality management, our lines process structural and industrial pipes according to ASTM A53, EN 10219, DIN, and JIS standards. We hold specialized patents for groove, shoulder, and victaulic connections.
Equipped with 4 pre-galvanized lines, 8 ERW product lines, and 3 hot-dipped galvanized process lines, our facilities process in excess of 300,000 tons annually. This ensures robust stock availability for massive structural runs.
From agricultural greenhouses to heavy petroleum and geothermal pipelines, we supply tailored specifications.
To comply with European directives and local customs specifications in Turkey, all steel shipments undergo a strict array of internal tests. We understand that mechanical reliability translates directly to jobsite safety.
This systematic approach has allowed us to achieve and maintain certification under ISO 9001 and municipal-level quality awards year after year.
We service procurement offices globally, ensuring local representation and face-to-face cooperation.
Detailed answers to key commercial and technical queries regarding black steel pipe imports to Turkey.
Black steel pipe is manufactured without a zinc coating. Its name is derived from the dark iron oxide coating formed on its surface during production. It is primarily specified for gas transmission lines, structural columns, industrial boilers, and steam systems where oxidation risks are low or where protective external coatings are applied on-site. Galvanized pipes feature a hot-dipped zinc layer for rust prevention, ideal for open-air construction and potable water supply.
We supply pipes meeting ASTM A53 (Grade A & B), API 5L (for oil and gas transmission), EN 10219 (structural hollow sections in Q235B, Q345B, S235, S355), and DIN equivalents. These materials are certified to support typical structural and plumbing pressures required by Turkey's engineering regulatory boards.
Our factory is located 40 km from XinGang port (Tianjin). We coordinate direct bulk vessel shipments or standard container bookings (FCL) to major Turkish ports including Istanbul (Ambarli), Kocaeli, Izmir (Alsancak), and Mersin. We provide complete documentation for local customs clearance, including Mill Test Certificates (MTC) to EN 10204 3.1, certificates of origin, and comprehensive packaging lists.
Yes. We supply pipes with plain ends, beveled ends for on-site welding, or threaded and coupled connections. Additionally, we hold patents for grooved (Victaulic-type) and shouldered pipe systems, allowing rapid assembly in mining and fire sprinkler systems.
For standard sizes (e.g. Schedule 40, Schedule 80), we maintain consistent stock. For custom dimensions or specific structural grades (like S355JR / Q345B), the MOQ typically ranges between 10 to 20 tons depending on the production schedule of our ERW/SSAW lines.
Select from our range of structural shapes, ERW line pipes, and large-diameter spiral welded models.
