ZINC ANODE MANUFACTURER
Zinc Sacrificial Anodes for Ships, Tanks and Offshore Structures
Custom zinc alloy sacrificial anodes for hulls, ballast tanks, rudders, sea chests, offshore structures and selected industrial marine service.
Zinc anode selection must be based on specified alloy chemistry, potential, electrochemical capacity, net mass, attachment and the actual seawater or brackish-water environment.

PRODUCT DEFINITION
Zinc Anodes for Defined Marine Service Conditions
Zinc sacrificial anodes are electrically connected to steel and consumed preferentially to supply galvanic protection current. Their performance depends on alloy purity and chemistry, closed-circuit potential, capacity, temperature, salinity, current demand, coating condition, anode resistance, geometry and electrical continuity.
Engineering Review Starts With Inputs
- ✓ Protected asset and environment
- ✓ Coating condition and exposed area
- ✓ Current demand and design life
- ✓ Alloy and electrochemical criteria
- ✓ Geometry and mounting interface
- ✓ Drawings, ITP and documentation

TECHNICAL SPECIFICATION
Parameters to Confirm Before Purchase
Use project-specific values. A generic catalogue value is not a substitute for the approved cathodic-protection calculation or purchase specification.
| Zinc alloy | Project-specified zinc alloy with controlled chemistry and agreed material documentation. |
|---|---|
| Potential and capacity | Declared only with test method, electrolyte, temperature, duration and reference-electrode scale. |
| Mass | Net zinc mass, gross assembly mass and permitted weight tolerance. |
| Core and mounting | Cast-in steel core, welding feet, strap, bolt-on plate, holes or brackets to approved drawings. |
| Shape and dimensions | Block, bar, plate, hull, tank or custom casting with controlled dimensions and surface condition. |
| Quality records | Chemical record, dimensional and weight inspection, continuity check, approved drawing, marking and packing. |
APPLICATIONS
Typical Protected Assets

MANUFACTURING AND QA
Control the Drawing, Alloy, Mass and Interface
Manufacturing review should confirm alloy charge control, mould and core arrangement, insert preparation, casting condition, dimensions, net mass, electrical continuity, marking and packing.
Inspection and document scope must be agreed in the purchase order. Any potential, capacity, efficiency or service-life statement should identify the governing test or calculation conditions.
Available Documentation by Order Scope
• Approved production drawing
• Alloy or chemistry record
• Net-weight inspection
• Dimensional inspection
• Insert or cable continuity
• Marking and packing record
• ITP and witness records
• Project-specific certificates

FAQ
Technical and Procurement Questions
How is the correct anode type selected?+
Selection must start from the protected asset, electrolyte or soil, resistivity, temperature, coating condition, approved current demand, target life, governing specification and installation constraints.
Can HELE manufacture to a customer drawing?+
Yes. Manufacturability can be reviewed against the approved alloy, net mass, dimensions, insert or core, cable, mounting, tolerances, marking and inspection scope.
What performance values should be specified?+
State the required potential, capacity or efficiency together with the alloy standard, test method, electrolyte, temperature, duration and reference-electrode scale. Unqualified values are not directly comparable.
What determines service life?+
Service life depends on actual current demand, coating condition, environment, alloy capacity, utilization factor, net anode mass, anode resistance, placement and electrical continuity.
What quality documents are available?+
Depending on the purchase order, the document package can include approved drawings, alloy or chemistry records, weight and dimensional inspection, continuity checks, marking, packing and agreed ITP records.
What should I include in an RFQ?+
Provide the structure and service environment, seawater temperature or resistivity, coating condition, approved current demand, design life, zinc alloy, model or drawing, net mass, core or mounting details, class requirements, quantity and schedule.
