Galvanising Services, Electroplating, Heat Treatment and More

In addition to a vast range of stock hardware and specialty fasteners, Prendergast offers a full range of metal treatment services to ensure improved durability, rust-proofing, corrosion-resistance and the fulfilment of a number of industry-specific requirements. Our services include but are not limited to:

  • Galvanising
  • Electroplating
  • Heat Treatment
  • Phosphating


This is the process of coating steel or iron with a layer of zinc. It’s extremely useful and offers a lot of advantages. We provide galvanising services Australia-wide, and not just for fasteners. If you’re looking for steel treatment specialists with top of the line equipment and an extensive history of providing expert galvanising services, you’ve come to the right place. The benefits of the galvanisation process include:

  • Rust-proofing
  • Corrosion-resistance
  • Scratchproof layering

A brighter finish

In the case of our galvanising services, we ensure full metallurgical bonding between the steel fasteners and the zinc finish for improved fastener lifespan, as well as variable spangling and different coating options.


For the best precision fasteners, we incorporate several electroplating techniques. This is the process of using electrical currents to plate metals and adapt their surfaces to extremely specific qualities. This is often used in the manufacture of specialty fasteners, as we can achieve a molecular level of accuracy, ensuring any custom fasteners are done precisely to specification. The benefits it offers are similar to that of our galvanising services, but incorporate different techniques.

Heat Treatment

A vital and precise science, we use heat treatment to manipulate the properties of our high carbon steel fasteners. We do both hardening and tempering, offering a wide range of characteristics across all our products. In short, proper heat treatment lets you decide exactly what kind of metal you want, making it an essential part of our manufacturing process, and one of our more popular services.


Phosphating is the process of coating metal with active substances. These react with the metallic components to form a layer of crystalline phosphates. Depending on the metal and compound used, phosphating can affect lubricity, corrosion-resistance and suitability for subsequent layering. It’s essentially like chemical galvanising, but with a slightly different array of results.

Our metal treatment and galvanising services have seen wide use across Australia’s industrial landscape. If you’re looking for any of these services, or would like to know more about them or our product range, reach us on 1800 074 094 or online.
