Difference between Raw steel, Clear coat and Zinc Finishes

Left- Raw Steel legs, These are un-coated raw steel. They will eventually rust if left untreated, perfect for a more industrial feel or ready for you to finish with your own choice. 

Center- Clear Coat, These still have all the charm and character of the bare steel but with protective clear coating that will last a lifetime. 

Right- Zinc, These legs have been electroplated in a zinc to give a bright, silver finish. This finish is extremely robust coating that will be suitable for outdoor use.
