The global industrial landscape is undergoing a massive transformation driven by electrification. In this era, SECD electrical galvanized steel coils have emerged as a critical material for motor manufacturers worldwide. SECD (Steel Electro-galvanized Commercial Drawing) is specifically engineered for applications requiring deep drawing properties and superior surface finish. Unlike standard galvanized steel, the electro-galvanization process ensures a highly uniform, thin zinc coating that does not interfere with the high-precision requirements of modern motor components.
With the rise of Industry 4.0, the demand for high-efficiency micro-motors, servo motors, and automotive actuator motors has surged by 15% annually. SECD steel provides the necessary ductility for complex motor housings.
Global manufacturers in Germany, Japan, and the USA prioritize SECD due to its excellent weldability and paint adhesion, which are vital for electric appliance and automotive "under-the-hood" components.
Electro-galvanized steel supports the "Green Energy" trend. It is 100% recyclable and its longevity reduces the lifecycle carbon footprint of the machinery it powers.
At STEP MILLION STEEL, our SECD electrical galvanized steel coils are produced using advanced cold-rolling and electrolytic zinc-coating technologies. The "D" in SECD signifies its Deep Drawing Quality, making it the ideal choice for motor shells that require deep stamping without cracking.
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.
Founded in 2010, STEP MILLION is a leading steel material supplier and manufacture in China, producing and supplying: 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, stainless steel sheet (coil) STS, aluminum sheet (coil) AL, silicon steel SI and other materials.
International procurement is shifting towards suppliers who can offer "Integrated Processing." We provide slitting, stamping, and coating all under one roof, reducing logistics costs for our clients in South America and Southeast Asia.
The Electric Vehicle (EV) sector demands lighter, more durable motor casings. Our SECD coils are increasingly used in EV auxiliary motors, where weight-to-strength ratios and corrosion resistance are non-negotiable.
Procurement teams now demand ASTM A591 and JIS G3313 compliance. Step Million Steel guarantees full traceability and certification (CE, ISO, GB) for every batch of SECD coils shipped.
Used in high-precision computer fans, hard disk drives, and office automation equipment where electromagnetic shielding is required.
Perfect for power window motors, seat adjustment motors, and wiper systems that face harsh environmental conditions.
Widely adopted by brands like LG Electronics for refrigerator compressors, washing machine motors, and air conditioner fan motors.
Structural components for CNC machines and robotics where SECD's drawability allows for complex, space-saving designs.
As a premier Wholesale SECD electrical galvanized steel coils manufacturer, we leverage China's world-class steel ecosystem. Our headquarters maintains strategic partnerships with giants like Hebei Iron and Steel Group, Baowu Iron and Steel Group, and Shougang Iron and Steel Group. This allows us to secure premium raw materials at competitive prices, a saving we pass directly to our global customers.
Technical expertise and operational excellence define our competitive advantages. With over 20 inspectors using testing equipment from Germany and Japan, we ensure that every square inch of our steel meets GB, ASTM, BS, or DIN certifications. Our ability to process more than 700,000 tons of steel annually with a turnover of nearly 4 billion yuan proves our reliability and financial strength.
Quality control remains our core priority, with rigorous production monitoring systems designed to eliminate the possibility of compensation claims. All products originate from reputable mills, utilizing premium raw materials and the latest technological advancements in strict accordance with international industrial standards.
