Large sheets of special enameling steel are sent from the mill to our factory. We begin fabrication by sheering the large sheets into individual signs. Intricate shapes can be formed using stamping dies or laser-cutting techniques. The steel then goes through a series of cleaning baths to prepare for coating. The first "ground coat" is applied and run through our furnace at 1470°F. This application is specially formulated to bond the porcelain to the steel. The steel is then given a second coating, a white "cover coat," and again run on a conveyor through our furnace. After cooling, these plates are ready for the application of artwork.​
