We all know that steel is the material of choice for obtaining great strength and rigidity. However, steel has the unfortunate tendency to rust very quickly if it is not adequately covered.
When the time comes to make a choice, various options are available to the consumer.
At Freeland Industries, we recommend the use of an electrostatic paint coating, commonly called "powdercoat". However, it should be noted that not all powdercoats are equal in terms of quality.
It is crucial to ensure that certain steps are incorporated into the coating process to maximize our chances of success.
Indeed, we live in Quebec, where winter really tests the quality of the surfaces, due to the humid conditions and the substantial quantity of salt spread on our roads.
In talking with several customers, we realized that there is a common misconception about powdercoat, that it is not a good coating for our winter conditions.
This is all false! Or almost. You see, a simple powdercoat without priming or proper preparation is not good for our winters. It is normal for American companies to only make a simple powdercoat, since they do not have the same corrosion problem as us.
For this type of coating to be optimal, it is imperative to add two crucial elements: high pressure sandblasting and the application of an epoxy primer.
Sandblasting:
High-pressure sandblasting involves blasting sand at high pressure onto steel. This procedure aims to rid the material of all impurities and the layer of scale that covers it, thus revealing the pure metal. In addition, sandblasting gives the surface a slightly rough texture, promoting paint adhesion.
Epoxy primer:
As for the epoxy primer, it is a layer applied before the final layer of powdercoat, which hardens when the parts first pass through the oven. This layer provides increased resistance to impacts and scratches, while providing considerable protection against corrosion.
Once these two steps have been completed, it is then possible to apply a layer of powdercoat.
One of the advantages of prepared powdercoat, as previously explained, is that when it is scratched, for example, after contact with rocks, the scratch does not tend to spread. Of course, there is nothing magical, so the scratch may rust. However, with the powdercoat and primer still covering the perimeter, corrosion will be limited to the exposed surface. This can then be covered with paint with a similar finish, in order to limit damage.
At Freeland Industries, all of our powder coated steel products are first subjected to high pressure sandblasting and accompanied by an epoxy primer. This ensures that you get the maximum protection from the elements.
