The single side PE coated aluminum coil is directly coated with a layer of high-performance polyester coating by the roller on one side of the aluminum coil. Its color is formed in the process of high temperature baking. It is very stable in performance and not easy to corrode. The prepainted aluminum coil can resist acid and alkali corrosion, as well as itself does not get corroded or produce mold.
In addition, the aluminum sheet in coil never releases any harmful gases, and does not need to carry out corrective painting. This ensures superior environmental performance. With such advantages, our single side PE coated aluminum coil has found wide use in the manufacturing of aluminum ceiling, aluminum-plastic composite panel, as well as other types of aluminum building material and aluminum decorative material.
