Real Estate / Construction companies in Poland [7]

Merged: Trade companies with building/construction materials in Poland

Hello everyone,
I've spent quite a while looking for companies, which trade with this type of materials. I guess it is because I am looking for them in english, it is extremely hard to find. If any of you can give me any particular names it would be very helpful.

P.S. I am not looking for producers or building companies, I am looking for import/export companies.
Thank you all :)
