YTDR Wholesale ERW Black Steel Pipe Factory

Our ERW structural pipes start with high-grade steel coils sourced from controlled mills. Using both hot-formed and cold-forming processes, we achieve a balance of ductility and hardness. The ERW seam is continuously monitored by automated systems, ensuring that every meter of pipe meets or exceeds ASTM A500, EN 10219, and JIS G3466 standards.

Technical highlights:

● Yield strength up to 550 MPa – Suitable for seismic zones and heavy industrial loads.

● Elongation rates exceeding 20% – Allows bending and welding without cracking.

● Tight outer diameter tolerance – ±0.5% for circular pipes, ensuring compatibility with connectors and joints.

● Available finishes: Black (mill scale), bare steel for painting, or pre-galvanized for corrosion resistance.

Our extensive manufacturing infrastructure allows us to cater to diverse industrial needs with unmatched flexibility. Whether you require standard sizes or bespoke configurations, our ERW black steel pipe offerings are designed to fit your exact specifications.

● Comprehensive Size Range: Circular pipes from Ø10.3–2032mm; square tubes from 10×10×0.5mm to 1000×1000×60mm; rectangular tubes from 10×15×0.5mm to 800×1200×60mm.

● Advanced Material Grades: Utilizing ERW, HFW, LSAW, SSAW, and seamless processes to deliver optimal mechanical properties for various load-bearing applications.

● Custom Processing: Offering secondary processing, cutting, welding preparation, and specialized coatings to reduce on-site labor costs.

● Dedicated PV Support Lines: Featuring 8 specialized lines for photovoltaic support structures, highlighting our adaptability to emerging green energy markets.

Unlike suppliers who outsource finishing, Yuantai Derun operates 26 in-house galvanizing lines and 10 pre-galvanized lines. This vertical integration means your ERW pipes can transition directly from forming to zinc coating without delays or quality gaps.

Customization options include:

1.Rectangular profiles – Up to 800×1200×60 mm for specialized architecture.

2.Lengths from 4m to 24m – Reducing on-site welding and installation costs.

3.Threaded ends, beveled ends, or grooved couplings – Ready for pipeline assembly.

4.Third-party inspection access – We welcome BV, SGS, or TÜV audits at our facility.

Yuantai Derun is not just a steel pipe manufacturer; we are a driver of sustainable industrial practices. Our ERW production lines are designed to minimize energy consumption and scrap generation. The use of structural steel pipes in construction reduces the carbon footprint compared to concrete or timber in many applications.

Logistics advantages:

● Proximity to Tianjin Port – Rapid export handling to North America, Europe, Southeast Asia, and the Middle East.

● 700M RMB registered capital – Financial stability to support large-scale contracts.

● 1600-acre storage yards – Enables just-in-time delivery and consolidation of mixed orders (ERW, LSAW, SSAW, spiral pipes).
