Description
MMO Cathodic Protection Anodes for Concrete Bridges
MMO mesh anodes are generally used for the cathodic protection of steel bars in concrete in atmospheric
environments. The mesh anodes are used together with titanium conducting sheets. The highly spread – out mesh
shape makes the distribution of the protection current more uniform.
Product Specifications and Performance:
| Width (mm) | Thickness (mm) | Length (mm) | Mesh Hole Size (mm) | Current Output (mA/m) | Lifespan (Years) |
|---|---|---|---|---|---|
| 10 | 0.6 | 76 | 2.5*4.6 | 1.32 | 30 – 100 |
| 13 | 0.6 | 76 | 2.5*4.6 | 1.65 | 30 – 100 |
| 19 | 0.6 | 76 | 2.5*4.6 | 2.42 | 30 – 100 |
| 25 | 0.6 | 76 | 2.5*4.6 | 3.2 | 30 – 100 |
The titanium base material uses mesh materials that meet the ASTM B265 Gr1 standard.
