Coating crafts types of color coated galvalume sheet

Color coated galvalume sheet coating means that people smear the painting on the substrates‘ surface thin and equably. With the development of the industry and technic, the industry has entered the automation, non-pollution and high efficiency stage. Today, CAMESTEEL will introduce three coating crafts of color coated galvalume sheet. They are roller coating, showing coating and powder coating.

A. Roller painting is a common way, which has a strong flexibility. And the color coated steel coils’ surface quality is very important. But the shortcoming is the roll marks.

B. Showing coating is another coating method. The paintings could outflow from the container bottoms’ crevice homogeneously. When it forms painting curtain, people could smear it on the substrate easily. It will not form roll marks. But the craft is a little hard to control because the coating weight waves largely with the speed’s change. So it is not applied into production wholesale.

C. Powder coating is another craft. People use the high voltage static to make the painting powder adheres on the substrate. The production method has a great combination property, and the quality is very stable. But is it too difficult to control, so it is not applied widely.
