I don't know any brands for doors, but try googling for brands and see if there are US distributors. The doors are usually solid all the way through (none of this plywood nonsense with cardboard in the middle) in addition to the bevel + rubber padding around the edge. Failing that, some of the major German "baumarkt" (building supplies stores) chains: http://www.hornbach.com/de/index.html http://www.hornbach.com/de/index.html http://www.obi.de/decom/home.html http://www.obi.de/decom/home.html https://www.toom-baumarkt.de/ https://www.toom-baumarkt.de/ Use google translate and see what you get. It might be worth investigating the pricing on a shipping container if you have an upcoming renovation or build in mind, shipping is cheap these days due to the global supply glut. If you have a friend who wants to do a project, a 40 foot container will cost you the same whether it's 10% or 100% full so you split the cost (weight doesn't matter). Try a shipping forwarder to the US or maybe you know someone in Germany and order to their address, and forward it.
