Thin-gauge precision steel coils maintain a thickness tolerance of ±0.005mm, meeting the precision machining requirements of microelectronic component housings.
In the efficient operation of the global industrial chain, steel coils, as "steel reels," connect the entire chain of steel production, processing, and application. Leveraging their standardization and intensive production processes, they have become a core raw material carrier for the automotive, home appliance, and construction industries. They not only drive a quantum leap in steel transportation and storage efficiency, but also, through technological iterations adapting to diverse industrial needs, inject key momentum into the scaled and refined development of the modern industrial system. They are arguably the "mobile steel foundation" of the industrial sector.
In automotive manufacturing, the high precision and stable performance of steel coils directly determine the quality of the vehicle body. Cold-rolled high-strength steel coils for automotive applications achieve a tensile strength exceeding 1500 MPa through a continuous annealing process. After laser welding and stamping, these coils can reduce vehicle weight by 20% while improving crash safety, meeting the dual requirements of lightweight and high strength for new energy vehicles. Galvanized steel coils, with a zinc layer uniformity error of ≤5%, provide long-lasting corrosion protection for vehicle exteriors, ensuring a service life exceeding 15 years in complex environments.
In the home appliance and construction sectors, the customized nature of steel coils demonstrates strong adaptability. Color-coated steel coils for home appliances achieve color reproduction exceeding 95% through a multi-color coating process, with a coating adhesion level of 0, meeting the aesthetic and durability requirements of refrigerator and washing machine exteriors. Color-coated steel coils for construction use a weather-resistant coating, improving UV aging resistance by 40%. They are widely used in steel structure factories and integrated housing, achieving the goal of shortening construction periods by 30%.
As industry transitions toward greener and smarter developments, steel coil technology continues to achieve breakthroughs. Thin-gauge precision steel coils maintain a thickness tolerance of ±0.005mm, meeting the precision machining requirements of microelectronic component housings. Full-lifecycle green steel coils utilize recycled steel and a low-carbon production process, reducing carbon emissions by over 25%. With their flexible form and superior performance, steel coils are driving cost reduction and efficiency gains across the industrial chain, helping global industry achieve its sustainable development goals.
