What are the root causes of the problem?

1. Paint quality: the purpose of scientific and technological progress is to promote the improvement of productivity, quality improvement, happiness index improvement. But some coating enterprises in order to improve the competitiveness of the scientific research direction on cost reduction and efficiency, with ultra-low cost of raw materials to replace, the production of resin synthetic coating, is the source of rapid fading, pulverization.
2. Corrosion resistance layer quality: according to the national standard color coated substrate galvanized layer should be 180 grams minimum, but now the general substrate coating thickness is only 8-12 grams, the corrosion resistance of the plate has not played a substantial role. Presume to be responsible for the production of enterprises should resist the production of this inferior alternative, low zinc layer color steel, do conscience products, do moral products.
