Currently, hot galvanization sheets and zinc aluminized sheets are widely applied into the coatings used in buildings. The thicker the layer is, the greater the corrosion resistance is.
The thickness of the cladding material could influence the erosion of the color coated steel‘s edge. And the erosion is the electrochemistry erosion. The influence factors refer to the pretreatment layers, primers, placodes thickness and cladding material’s thickness.
The acidity and alkalinity of the service environment decide weather to adopt the hot galvanization sheets or zinc aluminized sheets. Zinc and aluminum are the metalloid, but they show some difference in the sour and alkali. The performance of pure zinc in the alkaline medium is better than that of the sibley alloy. And its performance in the pickle medium is reverse. Therefore, it is better to adopt the zinc aluminized sheet in the acid environment. And it’s better to adopt the pure hot dip galvanization in the acid environment. And it shows that the wet lumber and concrete should not touch aluminum and zinc placodes for a long time.
