MMO Mesh Ribbon Anodes for Reinforced Concrete Cathodic Protection
HELE manufactures expanded MMO-coated titanium mesh ribbon anodes for reinforced-concrete ICCP, repair and distributed-current applications, with mesh geometry, active area, spacing, conductor-bar connections and design-life basis reviewed against the project conditions.
Share the concrete structure, repair area, concrete resistivity, chloride condition, required current, mesh spacing, conductor-bar layout and design-life target.
What Is an MMO Mesh Ribbon Anode?
An MMO mesh ribbon anode is an expanded titanium mesh-ribbon structure coated with mixed metal oxide and used as the active anodic element in distributed impressed-current cathodic-protection systems, particularly where open geometry and embedment in concrete or repair material are required.
MMO Mesh Ribbon
Expanded open-mesh titanium geometry with MMO coating, providing an active electrode structure with distributed exposed surface.
Solid MMO Ribbon
A continuous solid flat MMO-coated titanium strip with a different contact and installation geometry, commonly selected for tank-bottom grid systems.

Raw Titanium Mesh
Uncoated titanium mesh is a substrate or raw-material product and should not be confused with an MMO-activated mesh ribbon anode.
Mesh Geometry, Dimensions & Active Area
Mesh width, expanded thickness, diamond opening, supplied length and active surface area should be reviewed together because they affect concrete contact, installation geometry and electrical design.

Note: Active Surface Area is model-specific and should be confirmed with HELE engineering based on the selected mesh geometry.
Rated Output & Design Life Depend on the CP Design
Rated mesh-ribbon output should be defined from verified active area, specified interface current density, MMO coating requirement, installation environment and the project design-life basis rather than from mesh width alone.
Active Surface Area
Expanded geometry defines the active area available for current discharge and must be verified for the selected mesh geometry.
Interface Current Density
The specified current density at the concrete or electrolyte interface forms part of the electrical design basis.
Rated Output
Output per metre should be calculated from verified active area and the agreed current-density conditions.
Design-Life Basis
Design-life values must be linked to coating requirement, electrical duty, environment and the agreed calculation or validation basis.
Design Inputs for Reinforced Concrete Cathodic Protection
Mesh-ribbon selection should be reviewed together with the concrete structure, chloride condition, resistivity, repair geometry, required protection current, anode spacing and installation method.

Conductor Bar, Connections & Concrete Embedment
Mesh-ribbon performance depends not only on the active MMO electrode but also on reliable electrical interconnection, stable positioning and controlled embedment within the concrete or repair system.
Titanium Conductor Bar
Provides electrical interconnection between mesh-ribbon runs according to the approved cathodic-protection layout.
Crossover Connection
Connection points should provide reliable electrical continuity and mechanical integrity according to the project specification.
Fixing & Positioning
Mesh ribbon should remain in the specified position and spacing during installation and concrete or repair-material placement.
Embedment Condition
Concrete contact, cover, repair material and surrounding environment should be considered in the final installation design.
Mesh Geometry, Coating & Connection Verification
Titanium Substrate
Titanium substrate condition and the required product form are reviewed against the agreed purchase specification.
Mesh Geometry
Width, expanded thickness, opening geometry and supplied length are checked according to the confirmed order requirements.
MMO Coating
Coating requirement and coated area are controlled according to the confirmed production specification.
Connection & Final Inspection
Connection condition, identification, dimensions and project-specific electrical checks can be included according to the agreed inspection scope.
* Documentation is provided according to the agreed purchase and inspection requirements.
