Zinc Hull Anodes
Available to the specified alloy, dimensions, net mass, attachment details, inspection scope and approved project drawing.
Aluminum and zinc hull anodes manufactured in weld-on, bolt-on and drawing-based configurations for commercial vessels, workboats and marine structures.
Hull-anode replacement should be based on vessel area, coating condition, current demand, alloy, net mass, mounting centers, drydock plan and class or owner requirements.

Hull anodes are selected and positioned to supply galvanic current to immersed steel areas. Bow, stern, rudder, propeller, sea chest and general hull zones can have different current demand and installation constraints. Alloy, anode mass, profile, insert, centers and weld or bolt details must match the approved vessel plan.
Final construction follows the approved drawing, alloy specification, mass, attachment and quality plan.

Use project-specific values. A generic catalogue value is not a substitute for the approved cathodic-protection calculation or purchase specification.
| Vessel zone | Hull, stern, rudder, propeller area, sea chest or defined marine-structure location. |
|---|---|
| Alloy | Specified aluminum or zinc alloy with agreed chemistry and electrochemical acceptance. |
| Model and mass | Anode profile, net sacrificial-alloy weight, gross assembly weight and tolerance. |
| Mounting | Weld-on or bolt-on configuration, insert, stud centers, hole pattern and access. |
| Design basis | Coated area, coating breakdown, current demand, seawater conditions and target life. |
| Documents | Drawing approval, alloy record, weight and dimensional inspection, marking and class documents by scope. |
Application labels help route the inquiry; the final anode selection still requires engineering inputs.
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.
Provide vessel type, protected area and coating condition, approved current demand or anode schedule, preferred alloy, model and net weight, mounting centers or drawing, class requirements, drydock date, quantity and destination.
HELE reviews manufacturability and supply scope. Final cathodic-protection design responsibility must be defined by the project parties.
