LARGE BLOCK ANODES
Applications: Large scale industry, infrastructure, tanker, wharf or other marine protection.Zinc-cow-horns

AMAC have hundreds of large block anode moulds capable of producing a wide range of sizes. Our current moulds are able to produce anodes of the following dimensions:

Length = 3000mm maximum
Width = 330mm maximum
Height = 330mm maximum

For anode sizes outside of these dimensions, new moulds can be made.




ANODE INSERT SELECTION
AMAC Cast onto a variety of insert types, depending on the method of attachment required.

This illustration on the right identified the most common insert types.

All steel is inspected prior to casting. If required, abrasive
cleaning is conducted according to Australian or International standards.



The following table represents a small proportion of the large block anodes we are able to manufacture.

ZINC BRACELET ANODES
Aluminium Bracelet AnodesApplications: Marine and Subterranean pipelines and pylons.


Manufacturing bracelet anodes for over 25 years allows us to meet almost any design requirements. The bracelet anodes below are the most common. Any combination of these elements, as well as anode length, thickness and weight can be incorporated to meet particular project requirements. If a project requires a uniquely designed bracelet anode, please contact our office.



AMAC has a strict set of quality control mechanisms designed to ensure that each anode will function at its optimum for its entire design life. These controls ensure that steel grades and welding processes meet Australian and International Standards, alloy composition is accurate, insert fabrication meets dimensional specification, coating of internal surfaces and steel work is correct and all anodes meet weight and dimensional requirements.

SPECIAL PURPOSE ANODES
aluminium-cone-anodes
AMAC has been manufacturing sacrificial
anodes for over 25 years, over that time
we have produced thousands of unique
anodes for special purpose applications.
We have the facilities to create any
shape or size.
