- Copper shell with stainless steel S-tube and a stainless steel corrugated pipe for reliable urinal connection. Corrosion resistant, easy to clean, and durable with low dirt retention. - Fine copper die casting with red embossing process. Copper with fewer impurities and a stable molecular structure provides a strong body that enhances corrosion resistance and helps prevent leakage. - PVD deep plating. The main body blank is hand-polished on high quality copper substrate. While three electroplating layers are common, this design uses five layers to improve hardness and scratch resistance, keeping the surface durable. - No external power supply, battery operated. Uses a DC 4-5 battery power supply in a sealed battery box, offering operation without external power. Use scenarios: - Suitable for high-traffic public restrooms, hotels, airports, malls, and office buildings where durability and long life are important. - Ideal for healthcare facilities and other environments that require strong corrosion resistance and reliable performance. - Practical for retrofit or new installations in areas with limited electrical wiring due to battery-powered operation.
