Stone coated metal roofing was refined during and after World War II in the United Kingdom, when the government requested materials that would protect corrugated steel roofs from the harsh climate. A coating of bitumen and subsequent covering by sand, stone or other materials proved effective at protecting the metal roofs and serving as camouflage against potential attack. Now this type roofing sheet is quite popular in the market. Based on this need, we developed stone coated roofing sheet machine, the working speed could reach 25m/min.
