Ningbo Yingzhou Yonglong Copper Products Factory

Ningbo Yingzhou Yonglong Copper Products Factory has been in business since 1991, which is typical for long-standing Chinese suppliers with deep industry roots. They offer a wide range of copper and brass hardware, pipe fittings, and auto/telecom parts — a common product mix for metal suppliers in eastern China. While their company is based in China, where such products are widely produced, the lack of verification on work email, phone, and business documents raises a red flag for buyer trust. Most reputable suppliers verify these details to confirm legitimacy and reduce fraud risk. Without verified contact or documents, buyers may hesitate to place large orders or share sensitive requirements. This makes it harder to validate their operations or ensure consistent quality. Buyers should request additional proof before engaging in serious business.
