What to look for in a cold galvanising coating

Corrosion can have a devastating impact on industries such as manufacturing. It might be said it corrodes more than just the metal itself – it also has the potential to eat into profit!

While it’s difficult to arrive at exact figures relating to the cost of corrosion, the Australasian Corrosion Association points to NACE International research that indicates the effects of corrosion can contribute between 3.5 to 5.2% of global GDP. Extrapolating those results for Australia’s GDP, remediating affected assets could be costing companies here an estimated $78 billion per annum.

One way of protecting against corrosion is by applying a cold galvanising coating to assets and equipment. It’s important to use the right coating though – one that offers ongoing high performance and durability!

Four essential elements of a cold galvanising coating

A good quality coating should offer the following as an absolute minimum:

  • High zinc content: zinc is critical in corrosion prevention. It acts as a ‘sacrificial anode’, meaning that it corrodes in place of the underlying metal.
  • Proven corrosion-resistance: testing of the product in different environments and scenarios is important to discover if it will suit the application requirements.
  • Good adhesion: the coating should grip tightly to the metal, otherwise it won’t offer the required protection, whether it has a high zinc content or not.
  • Quick dry time: time is money as they say, so a coating that doesn’t take days to dry is important in avoiding long downtimes.

Application thickness is another consideration. Even with the best product out there, skimping on the coating thickness will mean the rust prevention won’t be as effective. In fact, skimping overall by using cheap, low-quality products is not a good idea – the rust will creep back in, and the whole process will likely start again.
