copper pipe

Hi. I’m from Kayseri in Turkey.

I sell Steel pipe since 1992 and this year so i have new idea. My city doesn’t have any seller about copper pipe and mechanical contractors want copper pipe so i search in Istanbul. I’m from Kayseri. Kayseri is located in the middle of Turkey. I can visit a lot of company and a lot of city in Turkey. But i'm searching strong companies about copper pipes.
Best Regards.
