Door - Equpment room to Drive through

[Jet-Stream]

I need a door to go from my equipment room to the drive through. The original owner put in a steel door but it has rusted to the point where it is not functional.
I looked at PVC doors but feel that they are not secure enough to keep bad guys out. Stainless is ridiculously expensive and hard to find. Possibly galvanized steel or fiberglass? Any suggestions / sources?
How about a reasonably price stainless door?
Thanks.

I am just replacing an extremely rusted door with a galvanized door. The last one I replaced with a frame and an opener, and all hardware was $680, a couple of weeks ago. This one is next to my IBA, and I also thought the pVC might be a little weak on security. If you don't find anyone in your area , a local company makes all sizes and custom also. I had thought of making a second door behind the pvc if I went that way for security- unfortunately i figured a $800 would be sacrificed by the late night guys -before they found the second door. I decided this time to make the threshold one concrete block high to stay out of the water, a little to step over, but I don't use the door that much.
