Our factory

Our manufacturing facility operates a comprehensive and modern production line, equipped with advanced continuous casting, precision rolling, high-speed drawing, and multi-axis CNC machining centers, enabling us to process copper and copper alloys (such as C10100, C11000, C12200, C71500,C70600 etc.) into a full range of products including tubes, sheets, rods, wires, and foils. To ensure top-tier quality, we have implemented a rigorous in-process and final inspection system, utilizing state-of-the-art equipment such as spectrometers for material verification, digital tensile testers for mechanical property checks, precision dimensional gauges, and eddy current or ultrasonic testers for defect detection, guaranteeing that every product meets or exceeds international standards such as ASTM, EN, and JIS, as well as specific customer requirements.
Pre-shipment inspection

We provide engineering-grade protective packaging for each and every product. Whether it's heavy copper tubes and plates, or precision rods, wires, and ultra-thin foils, we employ multi-layer composite protection: the inner layer uses scratch-resistant PE film and custom padding for physical isolation and cushioning; the middle layer is treated with moisture-proof sealing and includes desiccants; the outer layer utilizes reinforced wooden crates or high-strength waterproof wrapping film, depending on the shape and weight, for stabilization and protection. This ensures that the products withstand moisture, oxidation, and impact during long-distance sea or land transportation, arriving in perfect condition at your site. In terms of delivery, we commit to efficiency and reliability: standard specification products can be prepared and shipped within 7-15 working days, while customized products will also enter production scheduling promptly. We maintain full transparency throughout the process, allowing you to precisely control timelines and ensure your project proceeds as planned.
