How we make pre-painted 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.
