Expanded MMO Mesh Ribbon · Concrete CP
HELE manufactures expanded titanium MMO mesh ribbon for reinforced-concrete protection and repair layouts. Mesh geometry, coated area, spacing, conductor-bar connections, embedment and the current-density basis are confirmed against the concrete CP design.
Engineering boundary: Width alone cannot define output or life. Use verified active area, specified interface current density, coating requirement, concrete condition and installation layout.
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.
Expanded open-mesh titanium geometry with MMO coating, providing an active electrode structure with distributed exposed surface.
A continuous solid flat MMO-coated titanium strip with a different contact and installation geometry, commonly selected for tank-bottom grid systems.

Uncoated titanium mesh is a substrate or raw-material product and should not be confused with an MMO-activated mesh ribbon anode.
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 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.
Expanded geometry defines the active area available for current discharge and must be verified for the selected mesh geometry.
The specified current density at the concrete or electrolyte interface forms part of the electrical design basis.
Output per metre should be calculated from verified active area and the agreed current-density conditions.
Design-life values must be linked to coating requirement, electrical duty, environment and the agreed calculation or validation basis.
Mesh-ribbon selection should be reviewed together with the concrete structure, chloride condition, resistivity, repair geometry, required protection current, anode spacing and installation method.

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.
Provides electrical interconnection between mesh-ribbon runs according to the approved cathodic-protection layout.
Connection points should provide reliable electrical continuity and mechanical integrity according to the project specification.
Mesh ribbon should remain in the specified position and spacing during installation and concrete or repair-material placement.
Concrete contact, cover, repair material and surrounding environment should be considered in the final installation design.
Titanium substrate condition and the required product form are reviewed against the agreed purchase specification.
Width, expanded thickness, opening geometry and supplied length are checked according to the confirmed order requirements.
Coating requirement and coated area are controlled according to the confirmed production specification.
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.

Before Requesting a Quote
Concrete cathodic-protection performance depends on the installed grid and interface, not on mesh width alone. HELE reviews mesh geometry and active area together with current distribution, conductor connections and embedment conditions.
Compare the adjacent product families only after the reaction, environment and supply boundary are clear.
Inside HELE
HELE reviews the titanium substrate, expanded geometry, coated area, conductor-bar interfaces and finished identification against the approved order schedule. Active-area calculations and acceptance evidence must use the selected model and agreed measurement basis.
Confirm titanium form, grade or order standard, dimensions and material evidence against the purchase specification.
Control the coating direction and active geometry to the agreed production basis; do not infer life from appearance alone.
Review electrical joints, cable or conductor interfaces, sealing and mechanical details included in HELE’s supply scope.
Verify dimensions, identification, visual condition, packing and the agreed inspection or document package before shipment.
Sampling, acceptance values, test methods and supplied records are finalized in the quotation, inspection plan or approved order documents.
