Method of manufacturing storm drain markers

A method of manufacturing a storm drain marker comprising the steps of:

• cutting a stainless steel plate to form a shaped plate defined by an outer edge, said plate having a thickness of about 0.0625 inches;
• pressing said shaped plate with a hi-tonnage power press forming at least one depression on a front surface of said shaped plate, and a 0.18 inch corner radius along said outer edge with a recess of about 0.187 inch depth on a back surface of said shaped plate;
• sandblasting a front surface and a back surface of said shaped plate;
• attaching said shaped plate to a carrier bar;
• applying at least one white porcelain frit coating by liquid or powder electrostatic spray to said shaped plate front surface;
• baking said shaped plate to a temperature of at least 1, 375 degrees Fahrenheit in an oven until said porcelain frit coating is dry;
• cooling said shaped plate;
• creating a decal substrate with a ceramic printer;
• heating said decal substrate in water having a temperature of at least 110 degrees Fahrenheit, and heating of said shaped plate to the same temperature as the heated water;
• positioning said heated decal substrate on said front surface of said shaped plate;
• displacing water and air trapped between said decal substrate and said shaped plate with a soft press applying at least 25 lbs. of pressure;
• fusing said decal substrate to said porcelain coated front surface of said shaped plate by placement in an oven having a temperature of at least 1,300 degrees Fahrenheit;
• cooling said shaped plate to an ambient temperature;
• detaching said shaped plate from the carrier;
• forming a recessed mounting surface approximate a storm drain;
• and
• applying an adhesive to the back surface of said shaped plate and permanently securing said shaped plate to a recessed mounting surface;
• wherein said shaped plate provides a storm drain informational marker.
