Permanent SS Cathode Plate For Copper
Permanent Stainless Steel Cathode Plate for Copper EW/ER
The Permanent Stainless Steel Cathode Plate is the industry standard for high-efficiency copper electrowinning (EW) and electrorefining (ER). Engineered by PRS, our plates utilize premium 316L stainless steel with a specialized 2B-grade surface finish to ensure the perfect balance between copper adhesion and easy automated stripping.
With a design life of 15 years, our cathode plates are fully compatible with ISA, OK, and other major global permanent cathode processes.

Advanced Engineering Features
Optimized 2B Surface & V-Groove
The blade surface is treated to a 2B-grade finish, ensuring a controlled roughness average (RA) that prevents "early drop" of copper while facilitating smooth mechanical stripping. The bottom of the blade features a precision-machined V-groove to ensure clean separation of the two copper sheets.
Robotic Laser Welding Technology
- Precision: High-penetration robotic laser welding ensures a metallurgical bond between the blade and the beam.
- Low Heat Distortion: Minimizes plate warping, ensuring perfect verticality in the electrolytic cell.
- Consistency: Eliminates the variability of manual welding, extending the plate's lifespan to 15 years.
High-Performance Edge Strip System
- Material: High-molecular-weight extrusion plastic.
- Durability: Oil, acid, and heat resistant.
- Fixing: Bonded with industrial adhesive and PVC rods to prevent electrolyte seepage, reducing "copper growth around the edge" issues.
Packing and International Delivery
Packing and International Delivery
To ensure your investment arrives in perfect condition:
- Protection: Each plate is interleaved with protective film to prevent surface scratches.
- Reinforcement: Conductive beams are protected with heavy-duty caps; edge strips are secured against impact.
- Crating: Securely bundled in sea-worthy steel frames or customized wooden crates for long-distance transport.
