Yes, we specialize in custom copper solutions. Send us your drawings, specifications, or sample photos, and our engineering team will design and quote a custom solution tailored to your requirements. We offer free design consultation and can provide 3D models for approval before production.

We primarily use C11000 (ETP - Electrolytic Tough Pitch) copper which is 99.95% pure, the industry standard for electrical applications. We also offer C10200 (oxygen-free) for high-temperature and brazing applications, and C12200 (DHP) for specific plumbing and heating applications. All materials come with mill test certificates.

We are ISO 9001:2015 certified. Every batch undergoes inspection at multiple stages: raw material testing (spectrometer chemical analysis, conductivity testing), in-process dimensional checks, and final inspection (100% dimensional and visual). We provide material test reports (MTR) with each shipment upon request.

Standard payment terms: 30% T/T deposit, 70% balance before shipment. For established customers with good payment history, we may offer more flexible terms such as L/C at sight or net terms. We also accept PayPal and Western Union for sample orders and small quantities.
