About Us
Established in 1998, Longway leverages the comprehensive industrial strengths of its parent company, Sunyon Group—spanning sectors such as coke, steel, and stainless steel—to position itself as a leading OEM of components for commercial vehicles (including buses, trucks, and trailers), serving both OEM production lines and the high-end aftermarket. The company invested $300 million to acquire fully automated production equipment from Germany and the UK, driving rapid business growth. Today, it has evolved into a modern “Industry 4.0” facility offering 1,000 product specifications (SKUs) and boasting an annual production capacity of 220,000 tons of castings and forgings, alongside 2 million machined parts. Its manufacturing capabilities encompass casting, machining, stamping, and forging processes.
While the company’s product line centers on braking systems—specifically brake discs and brake drums—it has expanded to offer a comprehensive range of components, including axles, suspension systems, and chassis systems.
Leveraging advanced production facilities and a comprehensive TS16949 quality management system, LONGWAY’s products have obtained USA FMVSS121 DOT certification and European ECE R90 certification, establishing a highly recognized brand image in the international automotive parts market.
