Metal is one of the most widely-used materials in construction today. The durability and versatility of metal products must be preserved by using an industrial coating to reinforce the integrity of each metal component.
Selecting the right industrial metal coating is critical when it comes to maximizing product performance over time. You have four options available to you when coating your metal products: galvanizing, anodizing, electroplating, and powder coating.
In applications where you need to protect your metal components against corrosion, galvanizing is the right type of metal finishing process.
Metal is dipped in a molten vat of zinc during galvanization. The zinc becomes bonded to the surface of the metal, creating a protective layer that will shield the underlying metal against exposure to the elements.
Galvanization is a common type of finishing process used to treat construction metals.
If the metal components that you will be working with are made from aluminum, anodizing is the right type of metal coating process. Aluminum creates a layer of aluminum oxide when it is exposed to oxygen.
This aluminum oxide layer acts as a natural protective barrier. Anodizing helps to thicken this natural protective layer so that the underlying aluminum remains structurally sound over time.
While the goal of any metal coating is to offer protection against corrosion, this is not the primary goal of the electroplating process. Electroplating is the process by which cadmium or chromium are attached to the surface of a metal object using an electrical current.
This process creates a smooth and attractive finish. Electroplating is the coating process of choice when treating any metal components that will contribute to the visual aesthetic of a construction project.
4. Powder Coating
Powder coating is another coating process that can enhance the visual appeal of a metal component.
Specialized dry powders that can contain a variety of color pigments are electrostatically attached to the surface of a metal object during powder coating. The component and the attached powder are then exposed to heat, which cures the powder and creates a permanent bond with the underlying metal.
Powder coating is a sustainable alternative to paint. Dry powders come in a wide range of colors, allowing you to enhance the visual aesthetic of any functional metal component.
Metal coatings play an important role in determining the look and durability of metal construction materials. Use the right coating process to maximize the lifespan of your metal products. For more information about industrial coatings, contact a local professional.
