Abstract

A coated metal article includes a ferrous metal substrate, and an abraded metallic coating on the substrate, wherein the abraded metallic coating has a substantially uniform patterned appearance which simulates the surface appearance of polished stainless steel. A top coating, which may be a relatively thick PVC coating or a thin coating of polyester, epoxy, or acrylic, may overlie the abraded metallic coating on an obverse side of the substrate. The metallic coating may be a Zinc-Nickel alloy and a pre-treatment coating may be applied beneath the top coating. A primer coating may be applied beneath the PVC top coating.

Claims (33)

1. A coated metal article comprising:

a ferrous metal substrate,

an applied abraded metallic coating on the substrate wherein the abraded metallic coating has a substantially uniform patterned appearance which simulates the surface appearance of polished stainless steel, and

a polymeric coating overlying the abraded metallic coating on an obverse side of the substrate, through which polymeric coating the substantially uniform patterned appearance is visible.

2. The article of claim 1 , wherein the substrate is cold rolled steel.

3. The article of claim 1 , wherein the metallic coating includes zinc.

4. The article of claim 3 , wherein the metallic coating is a Zinc alloy.

5. The article of claim 4 , wherein the alloy is a Zinc Nickel alloy.

6. The article of claim 5 , wherein the alloy is about 11% Nickel.

7. The article of claim 1 , wherein the substrate is a metal sheet.

8. The article of claim 7 , wherein the substrate is in the form of a continuous strip.

9. The article of claim 8 , wherein the substrate is less than 0.09 inch thick.

10. The article of claim 1 , wherein the abraded metallic-coating has a roughness (R a ) less than 20 μin.

11. The article of claim 10 , wherein the abraded metallic-coating has a roughness (R a ) in the range of from about 5 to about 15 μin.

12. The article of claim 1 , wherein the polymeric coating is PVC and has a thickness in the range of from about 1.5 mils to about 2.5 mils.

13. The article of claim 12 , wherein the article further comprises a primer layer between the PVC coating and the abraded metallic coating.

14. The article of claim 13 , wherein the primer layer is an acrylic-based coating.

15. The article of claim 13 , wherein the primer layer has a thickness in the range of from about 0.10 mil to about 0.4 mil.

16. The article of claim 1 , wherein the polymeric coating is a polyester, epoxy or acrylic coating and has a thickness in the range of from about 0.15 mil to about 0.6 mil.

17. The article of claim 1 , wherein the article further comprises a pretreatment layer disposed on the abraded metallic coating.

18. The article of claim 17 , wherein the pretreatment layer is a complex oxide-based layer or Cr-containing coating.

19. The article of claim 1 , wherein the abraded metallic coating has an applied weight greater than or equal to 15 g/m 2 of surface area.

20. The article of claim 1 , wherein the abraded metallic coating has an applied weight in the range of from about 10 to about 30 g/m 2 of surface area.

21. The article of claim 1 , wherein the article further comprises a clear backer coating on a reverse side of the substrate.

22. A coated metal article comprising:

an abraded electrogalvanized steel substrate having a substantially uniform patterned appearance which simulates the surface appearance of polished stainless steel,

a pre-treatment coating on an obverse surface of the abraded electrogalvanized substrate,

a primer coating on the pre-treatment coating, and

a PVC coating on the primer coating.

23. The article of claim 22 , wherein the abraded electrogalvanized steel substrate has a roughness (R a ) in the range of from about 5 to about 15 μin.

24. The article of claim 22 , wherein the pre-treatment coating is a complex oxide-based layer or Cr-containing coating.

25. The article of claim 24 , wherein the primer coating has a thickness in the range of from about 0.10 to about 0.4 mil.

26. The article of claim 21 , wherein the PVC coating has a thickness in the range of from about 1.5 mils to about 2.5 mils.
