A method for making a decorative metal sheet through means of a coiled strip blasting line. Coiled metal strip is unwound, passed through a blast room, and rewound at the exit end of the line. In the blast room section, a mixture of recycled blasting media is combined with fresh material to create a controlled, steady-state blast media mixture that is projected, by a bank of air pressure nozzles onto the surface of the strip to create the desired decorative effect.
