The roofing sheet machine produced for Bulgaria customer was ready last week and we tested it yesterday. This is our old customer, we already cooperated several times before. His last roofing heet machine are bought from other supplier. Because our machine is 3000 USD expensive than others, so he choosed to buy machine from other supplier. But after the machine reached their factory and when he is using it he find the rollers polishing are not very good. There are some burrs on the rollers and they damage the color of the sheet. He said this will influence the selling of his roofing sheet. So this time he came back to us and give he order to us. Our this machine is FOB 13500 USD. The machine speed is 8-12 m per minute.
