Powder Coated Aluminum Fence – How is it Done?
If you’re like me then you’ve realized the durability and elegance of a powder coated aluminum fence, but you’re still curious about how it’s done. I’m a real “how did they do that” kind of guy and I spent some time looking into the process. It’s really very interesting, and complicated, so I’ll try to summarize as best I can and hopefully you will either find this satisfies your curiosity or you feel inspired to do more research yourself. Either way, let us continue. Preparation is a big factor in the powder coating process, as any foreign debris will ruin the finished product. Cleaning is done through a variety of methods, depending on the manufacturer, and usually depends on the size of the material and the type of debris to be removed. Generally cleaning is done through a chemical or mechanical process. Although chemical processes typically make use of chromates (which is hazardous to the environment), other process have recently been developed that avoid the use of these chemicals
