Porcelain Enamel

Porcelain enamel is a glassy composition applied to metal and fused thereon at a low red or bright red heat.  Although it is a glass, it must adhere to metal and resist punishment, both by impact and by rapid changes in temperature. (Porcelain Enamel Institute Technical Manual PEI 1301) 

The properties of the finished coating allow it to be used in a wide variety of applications.  Porcelain enamel has a higher melting temperature than most plastics, allowing it to be used in the appliance industry.  Barbeque grills, stove grates, oven cooktops and cavities are coated in porcelain enamel to prevent the deterioration of the metal substrate when subjected to high temperatures. 

Signs can be coated and screened to provide a finish that will not rust, and is scratch resistant.   Architectural panels can be enameled for durability and a finish that won't fade like paint.  In addition, porcelain enamel is less succeptable to the environment, more chip resistant, and easier to clean!  Porcelain enamel can also be made in many different colors.  Roesch can color match to your specific application.
