Power steel rod rust methods are there? Many power rust steel bar method, briefly as follows: where is the power with anti-rust paint steel bar most popular and most commonly used solutions. 1. If the power to change the composition of steel rod metal, increasing copper, chromium or nickel and other alloying elements; 2. The use of metal plating protection, such as electroplating or hot-dip galvanizing and other methods; 3. treatment with chemical oxidation power steel rod protection, such as phosphate treatment, the upcoming steel immersion solution containing hydrogen phosphate, iron phosphate and manganese hydrogen phosphate, the resulting iron phosphate and manganese phosphate insoluble protective film; 4. Non-metallic corrosion protection layer, such as coatings, plastics and other metal surface will power steel rod protected, so that from the media
