In the modern industrial landscape, DD11 HRPO (Hot Rolled Pickled & Oiled) Steel represents a critical bridge between standard hot-rolled and cold-rolled materials. As a premier wholesale manufacturer, we specialize in producing DD11 grade steel that adheres to the EN 10111 standard, renowned for its excellent drawing and forming properties.
The "Pickling" process involves passing the steel through an acid bath to remove the oxide scale formed during hot rolling, while "Oiling" provides a temporary protective barrier against corrosion. This resulting surface is clean, smooth, and ready for high-precision processing, making it the preferred choice for manufacturers who demand a superior surface finish without the cost of cold-rolled steel.
Optimized for complex shapes and structural integrity.
Professional oil coating prevents atmospheric oxidation.
The global demand for DD11 HRPO Steel is currently experiencing a significant upswing, driven by the rapid growth of the automotive and home appliance sectors in emerging markets. Currently, the industry trend is shifting towards "Green Steel" initiatives and high-precision manufacturing. Global procurement officers are increasingly looking for suppliers who can provide not just raw materials, but integrated solutions that reduce downstream processing costs.
From South America to Southeast Asia, enterprises are seeking China-based HRPO manufacturers due to our ability to combine large-scale production with stringent quality control. The trend of "Lightweighting" in the automotive industry has further propelled DD11 steel into the spotlight, as it offers a perfect balance of ductility and strength. Furthermore, the stabilization of global supply chains has emphasized the need for "Just-in-Time" delivery, a service model that STEP MILLION STEEL has perfected over a decade of operation.
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 factory, and have more than 300 employees and eight High Frequency welded lines.
Each line has a complete set of equipment to accomplish at least five production steps. All of this gives us a monthly output of 100,000 tons, half of which is exported. These facilities also include a molding workshop complete with 20 R&D engineers possessing over 10 years’ experience.
We provide a comprehensive range of materials including pre galvanized steel pipe, hot dip galvanized steel pipe, ERW pipe, square and rectangular tube, scaffolding tube, steel plate coils, cold-rolled steel sheet (coil) SPCC, pickled steel sheet (coil) SPHC, galvanized steel sheet (coil) SGCC/SECC, and more.
Over 20 inspectors, with over 10 years’ experience, will find the suitable raw materials for your order. All of our raw materials have GB, ASTM, BS or DIN certifications. CE certifications are available upon request. To accomplish this, we use testing equipment from Germany and Japan.
We maintain close cooperation with major steel plants in China, establishing long-term stable strategic partnerships with industry giants:
Selling more than 700,000 tons of steel annually with a turnover of nearly 4 billion yuan, we define the market standard for reliability.
Our massive 100,000-ton monthly output allows us to offer wholesale prices that localized suppliers simply cannot match.
Utilizing high-frequency welding lines and German-imported testing gear ensures every coil meets the tightest tolerances.
Strategic locations near major ports ensure expedited delivery to Middle & South America, Southeast Asia, and the Middle East.
From structural components to decorative finishes, our steel powers global growth.
Understanding the localized application scenarios is key to our success. In the Middle East, our HRPO steel is widely used for HVAC ducting and electrical enclosures where surface cleanlines is paramount. In Latin America, the automotive aftermarket relies on our DD11 grade for stamping body parts. We offer flexible cooperation terms, including the acceptance of small-scale initial orders to facilitate trust before formal long-term partnerships.
Our service framework is built on efficiency. A standardized response protocol ensures that all inquiries are addressed within 24 hours, with comprehensive solutions provided within 48 hours.
