MMO Mesh Ribbon Anode | Impressed Current CP for Reinforced Concrete
Our MMO Mesh Ribbon Anodes represent a significant advancement in impressed current cathodic protection for reinforced concrete structures. Unlike traditional anodes, the unique mesh configuration provides exceptional surface area while maintaining the flexibility needed for installation in complex concrete geometries — from curved bridge decks to multi-level parking garages. This design ensures uniform current distribution and long-term reliability in the most challenging environments, including those exposed to de-icing salts and seawater.
Why choose mesh over solid ribbon? The open grid structure allows concrete to flow through during placement, creating a superior mechanical bond. This eliminates the risk of “debonding” — a common failure mode for solid ribbon anodes — and ensures consistent protection for the full design life of 20+ years.
Primary Applications
| Application | Key Benefit |
|---|
| Bridge Decks & Infrastructure | Superior corrosion protection for horizontal concrete surfaces exposed to de-icing salts |
| Parking Structures | Multi-level garage protection against chloride penetration |
| Marine Structures | Piers, wharves, and sea walls in saltwater splash zones |
| Industrial Buildings | Chemical plants and processing facilities with corrosive atmospheres |
Enhanced Performance Features
Optimized Surface Area
Mesh design provides significantly increased surface area compared to solid ribbon anodes, enabling higher current output and improved efficiency — up to 40% more active area per linear meter.
Superior Flexibility
Maintains excellent bendability for installation on irregular surfaces, curved edges, and complex structural elements where rigid anodes would be impractical.
Enhanced Concrete Adhesion
The open mesh structure allows concrete to fully encapsulate the anode, creating a superior mechanical bond that eliminates the risk of delamination — a common failure point for solid ribbon systems.
Uniform Current Distribution
Grid pattern ensures even current emission across the entire protected surface, eliminating directional bias and weak spots that can lead to premature corrosion.
Durability in Alkaline Environments
Specially formulated MMO coating is resistant to high pH concrete environments (up to pH 13), ensuring stable performance for decades.

Frequently Asked Questions
Q: How does mesh design improve performance over solid ribbon?
A: The mesh configuration provides increased surface area for higher current output and better concrete adhesion (concrete flows through the mesh), while maintaining flexibility for easy installation. Solid ribbon anodes risk “debonding” over time.
Q: What is the recommended spacing for mesh ribbon anodes?
A: Typical spacing ranges from 0.8 to 1.5 meters, depending on concrete resistivity, reinforcement density, and protection requirements.
Q: Can mesh ribbon be installed in vertical applications?
A: Yes, the mesh design provides excellent concrete adhesion and can be installed in vertical, overhead, and horizontal orientations — it stays in place during concrete pour.
Q: How is the mesh ribbon connected to the power supply?
A: We provide integrated connection systems including titanium feeder bars, welded connection points, mechanical clamps, and complete junction box assemblies.
Q: What is the typical design life in real-world conditions?
A: Our MMO mesh ribbon anodes are designed for 20+ years of maintenance-free operation in concrete environments, including those exposed to de-icing salts and marine chlorides.
