SMSTEEL
STEP MILLION STEEL SUPPLY CHINA CO., LTD., founded in 2010, is a premier industrial hub for high-grade 40/40 Electro-Galvanized (EGI) steel. Based on over 15 years of technical expertise, we specialize in SECC, SECD, and SECE steel plates and coils that meet the rigorous standards of global markets.
Our facility spans 66,700 square meters, housing 8 high-frequency welded production lines and a specialized molding workshop. With over 300 dedicated employees and 20 R&D engineers, we achieve a monthly output of 100,000 tons, ensuring that we can handle high-volume wholesale demands without compromising on precision.
Electro-galvanized steel with a 40/40 coating weight (40g/m² per side) has become the gold standard for industries requiring superior surface finish and consistent corrosion resistance. Unlike hot-dip galvanization, the EGI process provides a uniform coating that preserves the mechanical properties of the cold-rolled base metal. Currently, North American and European automotive sectors are driving massive demand for SECC/SECD materials for internal components and visible panels.
The industry is shifting toward "Smart Steel" and sustainable manufacturing. There is a growing trend for RoHS-compliant, finger-print resistant (AF) coatings on EGI sheets. Modern manufacturers are integrating AI-driven quality control to ensure that the 40/40 coating thickness is strictly maintained across the entire width of the coil, reducing waste and improving downstream performance in stamping and welding.
China accounts for over 50% of the world's steel production. Factories like Step Million Steel leverage integrated supply chains with giants like Baowu and Shougang to offer competitive pricing and superior raw material quality. Our proximity to major shipping ports and high-tech manufacturing clusters allows us to offer lead times and logistical efficiencies that are unmatched globally.
40/40 EGI refers to the zinc coating weight applied via electrolysis. This specific weight offers a balance between cost-effectiveness and long-term durability.
| Grade | Description | Common Applications |
|---|---|---|
| SECC | Commercial Quality, Cold Rolled | Computer cases, electrical cabinets, general hardware. |
| SECD | Drawing Quality | Automotive parts, deep-drawn appliance shells. |
| SECE | Deep Drawing Quality | Complex curved components, high-end electronics. |
In high-tech hubs like South Korea, Japan, and the USA, 40/40 EGI is used for high-end server racks and chassis. The 40/40 coating provides excellent EMI shielding and a smooth surface that is ideal for powder coating or painting without the "spangle" look of hot-dip steel.
EGI is essential for automotive interiors and exposed parts where precision is paramount. OEMs (Original Equipment Manufacturers) require the 40/40 weight for parts like door frames and seat rails, where spot welding performance and paint adhesion are critical for vehicle longevity.
Major brands such as LG and Samsung utilize our SECC steel for refrigerator side panels, washing machine drums, and microwave interiors. The anti-corrosive properties of the 40/40 zinc layer protect appliances in humid environments (like Southeast Asia and Latin America).
Global buyers are no longer just looking for the lowest price; they are looking for supply chain resilience and technical certification. Our customers in the Middle East and Africa prioritize materials that can withstand high salinity and temperature fluctuations. Meanwhile, European buyers demand CE and DIN certifications to meet strict building and safety codes. STEP MILLION STEEL meets these needs by providing testing equipment from Germany and Japan to verify every batch.
Over 20 inspectors with 10+ years of experience monitor every production step. We utilize ASTM, BS, and DIN standards, ensuring zero compensation claims for our clients.
We maintain deep cooperation with Baowu, Shougang, and Anshan Iron and Steel Group. This ensures a steady supply of premium cold-rolled base materials for our EGI lines.
With an annual turnover of 4 billion yuan, we serve nearly 100 countries. Our team provides solutions within 48 hours for any complex procurement inquiry.
When selecting 40/40 EGI steel, engineers are looking for a material that offers high aesthetic appeal alongside functional protection. The "40/40" designation indicates that 40 grams of zinc have been applied per square meter on each side of the steel. This is a significant upgrade from the 20/20 standard, providing double the corrosion protection without significantly increasing the thickness of the material. This makes it ideal for precision engineering where tolerances are tight.
In the context of global procurement, EGI is often favored over hot-dip galvanized steel for electrical enclosures because EGI provides a smoother surface for grounding and electrical contact. Furthermore, Step Million Steel ensures that our 40/40 EGI is treated with specialized chemical passivation or oiling to prevent "white rust" during ocean transit, a common concern for international wholesalers in South America and Southeast Asia.
As the automotive world moves towards electric vehicles (EVs), the need for lightweight yet durable materials is skyrocketing. 40/40 EGI SECE grades allow for complex stamping of battery enclosures and internal electronic frames, offering the ductility of cold-rolled steel with the protection of a high-performance zinc layer. Our factory’s R&D team continuously works on improving the adhesion of these coatings to support the latest welding technologies used in smart factories worldwide.
By choosing Step Million Steel, you are partnering with a manufacturer that understands the nuances of the steel industry. Our strategic partnerships with Shougang and Baowu Iron and Steel Group mean we have first-hand access to the best raw materials, which we then process using state-of-the-art Japanese and German equipment. Whether you are a local distributor in the Middle East or a large-scale manufacturer in Europe, our 100,000-ton monthly capacity ensures that your supply chain remains uninterrupted and your product quality remains world-class.
