Corrosion Protection

Corrosion occurs when a metal gradually deteriorates as a result of a reaction between the material and its environment (e.g. water or oxygen). Rust is perhaps the best-known example, and can affect the look and functionality of equipment. Corrosion often impacts on the strength and movement of the metal and can result in a hefty bill to fix or replace the object. In fact, Australia faces an annual cost of billions of dollars because of corrosion, due largely to the fact that most of our cities are in coastal areas – salt water rapidly accelerates corrosion.

So we know it is important to do what we can to avoid corrosion, but is corrosion protection safe? Many corrosion protection products produce highly toxic, carcinogenic compounds that offer protection at the cost of our health and the environment. It is a good idea to find a company that is committed to customer safety and offers a range of corrosion protection options.

During Cathodic Protection, another metal is applied to the original equipment surface to react with air and water – instead of the metal beneath it getting damaged. Prevention is always better than cure, so Cold Galvanizing products are available to provide long term protection of steel. Cold Galvanizing – a form of Cathodic Protection – is a corrosion protection process that helps protect steel from rusting by applying a layer of zinc rich paint. Rather than water and oxygen impacting on the metal, the reaction occurs with the zinc, and the metal remains intact. Cathodic Protection can assist in the prevention of stress corrosion cracking.

It is essential to find products with a high zinc concentration – this is important for providing a strong barrier between the equipment and the elements. If the percentage of zinc in the product is too low, Cathodic Protection cannot occur. A product that contains around 98.5% pure zinc and 92% metallic zinc in the dry film is a good guide. It is also unique in its self-healing ability – if the dry product is scratched the scratched surface is automatically resealed.

Investing in corrosion protection products pays off. All metal can corrode, and not only can corrosion affect the look and function of equipment, it can also put your family or colleagues in great danger. Proper maintenance is essential, and the right products will save you money in the long term. Corrosion control is something that must be maintained constantly, and if corrosion protection treatments are applied to new equipment and properly maintained, the chances of any corrosion is highly unlikely. For pieces that have already corroded, they can often be fixed – and further damage prevented – with corrosion protection products.  

Industry experts agree that zinc coatings are excellent, if not the best, method of long term corrosion protection. Most corrosion protection products are easy and quick to prepare and apply, high in zinc, and suitable for new equipment as well as older gear that needs restoring. These Corrosion Resistance products can lower your maintenance costs and extend the lifespan of your equipment.
