Abstract: Equipment for manufacturing a metal strip coated by a process that includes vacuum-depositing a layer of an oxidizable metal or an oxidizable metal alloy on a metal strip precoated with zinc or with a zinc alloy, then coiling the coated metal strip, then oxidizing a surface of the metal strip coated with the oxidizable metal or oxidizable metal alloy and treating the oxidized wound coil with a static diffusion treatment to obtain a strip having a coating that includes, in an upper portion, a layer of an alloy formed by diffusion of the oxidizable metal or the oxidizable metal alloy in all or part of the zinc or zinc alloy layer. The equipment includes a device for galvanizing the metal strip, a vacuum deposition coating device, and a static heat treatment device operating in a controlled atmosphere.
