I had a look at the UK and found a company called http://www.doorsets.org.uk http://www.doorsets.org.uk. These guys look like they import these kind of doors into the UK, and they say their brands are manufactured by a company called Grauthoff. They have an English site at http://www.grauthoff.com/en/ http://www.grauthoff.com/en/ - I couldn't find any USA importers but there might be some leads for you to try out there. Best of luck. Perhaps someone from Grauthoff can tell you if they export, or possibly there are companies similar to Grauthoff.
