The steel armor band has zinc protective layer on its two sides, and uncoated edges, to reduce manufacturing costs and improve cathodic protection. The zinc protective layer thereby comprises a first layer portion consisting of a zinc-iron alloy and a second layer portion, on top of said first layer portion consisting of essentially pure unalloyed zinc and having a thickness of at least 90% of the total layer thickness.
