The global steel industry is undergoing a significant transformation, with the demand for Round Pipe String Manufacturing Plants reaching unprecedented heights. As infrastructure projects across Southeast Asia, the Middle East, and South America accelerate, the requirement for high-precision, high-frequency welded round pipes has become a cornerstone of modern engineering. Today's manufacturing landscape is no longer just about volume; it is about structural integrity, environmental sustainability, and smart production strings.
A "Pipe String" in a manufacturing context refers to the continuous, integrated sequence of production—from raw coil decoiling and leveling to high-frequency welding, sizing, and automated cutting. Modern factories are now integrating AI-driven monitoring systems to ensure that each "string" of production maintains sub-millimeter precision, meeting the rigorous standards of ASTM A106 and BS EN requirements.
STEP MILLION STEEL SUPPLY CHINA CO., LTD. founded in 2010, is a leading steel material supplier and manufacturer in China. Our production facilities cover over 66,700 square meters and employ more than 300 dedicated professionals, including 20 R&D engineers with over 10 years of experience.
We operate eight High-Frequency welded lines, each equipped with a complete set of machinery to accomplish at least five rigorous production steps. This infrastructure enables a massive monthly output of 100,000 tons, with 50% of our capacity dedicated to global exports.
Our strategic partnerships with giants like LG Electronics, Xizi United, and Baowu Iron and Steel Group underscore our reliability and authoritative position in the steel industry.
Our 20 R&D engineers utilize advanced modeling and mold-making workshops to customize round pipe string configurations for specific industrial needs, ensuring seamless integration in construction and automotive frameworks.
Over 20 inspectors with 10+ years of experience monitor every batch. Utilizing testing equipment from Germany and Japan, we ensure compliance with GB, ASTM, BS, and DIN certifications.
Established long-term strategic partnerships with Hebei Iron and Steel Group, Baowu, and Shougang ensure we always have access to premium raw materials even during market fluctuations.
Global buyers from construction, agriculture, and manufacturing sectors seek round pipe strings that offer a balance of cost-efficiency, durability, and standard compliance. Whether it is for high-rise scaffolding or corrosion-resistant greenhouses, Step Million Steel provides the localized solution needed.

With an annual turnover of nearly 4 billion yuan and 700,000 tons sold domestically, our economies of scale allow us to offer factory-direct wholesale pricing that local distributors cannot match.
All inquiries are addressed within 24 hours, with comprehensive solutions provided within 48 hours. We facilitate trust through flexible initial order scales.
Our products originate from reputable mills, using premium raw materials in strict accordance with international standards (CE available upon request).
From ERW and Hot-Dip pipes to specialized ZM/AZM coatings for solar mounting, we are a one-stop-shop for global steel procurement.
The manufacturing process at a wholesale round pipe string manufacturing plant involves complex thermo-mechanical cycles. It begins with the selection of high-quality carbon steel coils (SPHC or Q235). These coils are fed into a series of forming rolls that gradually curve the flat steel into a circular shape. In the High-Frequency (HF) welding stage, the edges are heated by induction and pressed together to form a solid, durable seam without the need for filler metals. This process is what defines the "ERW" (Electric Resistance Welded) pipe, known for its consistency and strength.
For industrial applications involving high-temperature service or pressure handling, ASTM A106 is the gold standard. Our manufacturing plants ensure that the wall thickness—often referred to as Schedule 40 (Sch 40)—is maintained with extreme precision. These pipes are indispensable in the oil and gas industry, as well as in chemical processing plants where reliability is paramount. As a leading manufacturer, we ensure that our ASTM pipes undergo hydrostatic testing and non-destructive electrical tests to ensure 100% reliability.
Corrosion is the primary enemy of steel. Our Hot-Dip Galvanized (HDG) and Pre-Galvanized production lines apply a protective zinc coating that significantly extends the lifespan of the pipe. Hot-dip galvanization, which involves immersing the pipe in a bath of molten zinc, provides a thicker coating suitable for harsh outdoor environments like agricultural greenhouses and coastal construction. Our high-zinc hot-dip pipes are specifically designed to withstand high humidity and saline air, making them a preferred choice for our clients in the Middle East and Southeast Asia.
Beyond pipes, Step Million Steel is a powerhouse in hot-rolled and cold-rolled steel plate manufacturing. Materials like SECC (Electro-galvanized) and SPCC (Cold-rolled) are the lifeblood of the automotive and home appliance industries. By maintaining close ties with the Baowu Iron and Steel Group and Hebei Iron and Steel Group, we ensure a steady supply of these materials to global markets, contributing to the manufacturing of everything from elevators to high-end electronics.
