Application:Using hot galvanized sheet and zinciron alloy hot galvanized sheet as the substrate, color coated sheet is made by first going through surface pretreatment, then the coating of one or more layers of liquid coating by roll coating, and finally baking and cooling. The coatings used including polyester ,silicon modified polyester, highdurability polyester, polyvinylidene fluoride,epoxy and high corrosionresisting coatings have good durability, corrosionresistance and formability. Color coated sheet is widely used in building, Transport, home appliances, solar energy,furniture, etc. In home appliances, it is mainly used as the side door plate of refrigerators,and shell of DVDs, air conditions,freezers,and washing machines.
How we make colored steel coil
1. We start with the base steel that is lightweight yet strong.
2. Next comes a protective zinc alloy coating applied to both sides by a continuous hot-dip method
3. A conversion coating is chiemically applied to the zinc steel to enhance corrosion resistance and ehcure bonding surface.
4. Next, a corrosion inhibitive high technology primer is applied and oven-baked.
5. Finally, a specially formulated high performance exterior paint finish is applied and oven-baked to the top or working side, giving a natural low-gloss finish.
6. The underside is finished in shadow grey, a light attractive backing coat that reflects and enhance the appearance of the visible underside of structure.
