What is a plastic coating?
After cleaning, the metal parts are treated with a wash primer and then coated electrostatically with a plastic powder. This coating is fluidified in a continuos furnace and surrounds the metal parts with a continuos layer of plastic.
This lamination is weatherproof. Nevertheless it can be damaged by mechanical means, by what the raw iron is exposed and thus may rust. The plastic coating can be done in all color shades and by way of comparison is rather inexpensive.
