Zinc Anodes
What are Zinc Anodes
Zinc anodes are sacrificial corrosion protection products used to protect steel and other metals from corrosion. They form part of a cathodic protection system and are designed to corrode instead of the structure or component they are fitted to.
When correctly installed, zinc anodes help protect submerged and exposed metal assets by drawing corrosion away from the protected surface.
Our Zinc Products
Zinc Anode
Variants
We manufacture zinc sacrificial anodes for marine, offshore, harbour and industrial applications
where reliable corrosion protection is required.
Standard Zinc Sacrificial Anodes
Standard zinc anodes are used for general cathodic protection across marine, harbour and industrial applications.
Zinc Weld-On Anodes
Weld-on zinc anodes are designed to be welded directly onto steel structures where a strong and fixed installation is required.
Zinc Bolt-On Anodes
Bolt-on zinc anodes are mechanically fastened to the protected structure, making them suitable for maintenance, replacement and accessible installation areas.
Zinc Shaft Anodes
Zinc shaft anodes are used on vessel shafts and underwater running gear to help protect metal components from corrosion in marine environments.
Zinc Round Bar Anodes
Zinc round bar anodes are supplied in cylindrical form for specialised cathodic protection applications, custom fabrication and project-specific marine or industrial requirements.
Why Zinc Anodes Are Used in Marine and Harbour Environments
Marine and harbour assets are exposed to moisture, seawater, salt spray and demanding operating conditions. Over time, this exposure can cause corrosion on vessels, pipework, tanks, submerged steelwork and marine infrastructure.
Zinc anodes are used because they provide reliable sacrificial protection in seawater environments and are suitable for a wide range of marine maintenance and infrastructure applications. They are often selected for vessels, ports, harbours, pipelines and equipment where corrosion control is essential.

Benefits of Zinc Anodes in the Ship Industry
Reliable Corrosion Protection
Zinc anodes help protect steel and other metals by sacrificing themselves in place of the protected asset.
Suitable for Seawater Applications
Zinc anodes are widely used in seawater environments, making them practical for vessels, harbour structures and marine systems.
Strong Marine Maintenance Support
They are commonly used for replacement, repair and ongoing maintenance across marine and industrial assets.
Versatile Product Options
Zinc anodes can be supplied in different shapes, sizes and configurations to suit various mounting and protection requirements.
Custom Manufacturing Options
Protea Foundry can manufacture zinc anodes to client specifications, including specific sizes, weights, steel core designs and installation requirements.
Wide range of protection applications
Applications
Zinc anodes are suitable for a wide range of marine, harbour and industrial corrosion protection applications, including ship hulls, tanks, pipework, harbour structures, jetties, marine equipment, offshore support structures and submerged steel components.
These applications require dependable sacrificial anodes that can support corrosion protection in harsh and exposed environments.
Project-Specific Requirements
Specifications
Protea Foundry supplies zinc anodes in standard and custom configurations, with weld-on and bolt-on options available where required. Custom steel core configurations, dimensional requirements and weight specifications are available upon request.
or project-specific requirements, clients can send drawings, measurements, quantities or technical specifications for review and quotation.
Zinc Anodes
Manufactured to client requirements
Zinc anode requirements can vary depending on the asset, installation method, water conditions, exposure level and required service life. Some projects require standard zinc anodes, while others need custom shapes, sizes or mounting configurations.
Protea Foundry can assist with zinc anodes for vessels, harbour structures, tanks, pipework, marine systems and industrial infrastructure.
