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.
Each bare coil to be securely tied with two bands through the eye of coil (or not) and one circumferential, the contact points of these bands on the coil edge to be protect with edge protectors. Coil then to be properly wrapped with water proof /resistant paper, it then to be properly and completely metal wrapped. And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance, and two-four such bands securely tied around belly of coil at about equal distance.
