Dear X company,
We have changed our location to move closer to the factory ((I am not sure what you meant here)),
so our new address is in the industrial zone.
We hope to hear from you soon.

With regards,

(name)

((You were almost right, but I didn't quite understand what you meant in the 2nd line. Hope I helped anyway!))
