Porcelain Industries' corrosion resistant and heat resistant porcelain enamel coatings, or vitreous glass coatings, improve the durability and appearance of cast iron and steel products such as appliances, signs, pipes, and architectural panels. Formulated with relatively inert inorganic oxides, vitreous enamels provide an impervious surface that is highly resistant to most chemicals. Porcelain coatings retain their original gloss and color, offer excellent corrosion resistance and protection against aqueous solutions of alkalis, adapt to the same level of hardness as the substrate to which it is applied, and are highly wear resistant. Moisture or rust cannot penetrate beneath well-applied porcelain enamel coating, so it will not flake away from exposed edges or damaged areas. Porcelain will usually not fracture due to impact unless the base metal is permanently deformed. Porcelain enamels are noted for their ability to appreciably reduce the oxidation of base metals. As a result, they lower costs and improve performance by permitting the use of less costly metal alloys. This extends metal life, and increases value.

Within our plant, Porcelain Industries dedicates half to steel applications, and half to cast iron applications. This is important for overall quality and volume requirements, because not all facilities meet every coating requirement. Porcelain enamel begins as "frit" - a type of glass that is scientifically formulated with clays, electrolytes, metal oxides, and water. Our lab and suppliers work together with you to select from over 50 such minerals in order to achieve different effects and properties you demand.

To successfully meet the special needs of your coated cast metal product, we apply a series of steps to the process that is unique to our industry. Achieving a long-lasting, durable porcelain enamel finish on cast products is one of our specialties. We offer advice on the best metals to use for your project, as well as insights into designs that will ensure the least amount of rework. This is important, because the process of applying a porcelain enamel coating puts the product under certain stresses during the application process. Cast iron products have unique requirements for how they are coated and fired. For example, the high heat necessary to bond porcelain to a cast iron substrate can result in product distortions during the firing process. Tooling designs that keep the forces of gravity and high heat at bay are necessary.

A product must fully meet design requirements and specifications, and it must be manufactured by the most economical methods to minimize your costs and maximize your profits.
