Metallizing is the generic term used for the technique of coating metal onto an object’s surface. Metallizing is an overarching term used to describe all processes under thermal spray.
The metallizing process starts with preparing the surface of the product. Then a metal wire is melted in metallizing spray equipment to become molten. After this, clean and compressed air atomizes the material, and the air then transports the atomized metal onto the product surface to form the coating.
Metallizing is considered a cold process because the metal material is sprayed onto the object’s surface rather than dip galvanizing the object. This decreases the chance of the object being damaged during the coating process.
Benefits of the Metallizing Process
Enhanced corrosion protection — Rust is a common issue when working with most metals and especially with steel. Metallization can create a protective coating that inhibits the development of red and/or white rust, increasing the product’s lifespan by as much as 20 years or more.
Increased durability — Most metallized coatings are known for their ability to adhere to the surface of the underlying workpiece or substrate. They are less likely to peel, blister, crack or flake than other types of finishes, which increases the substrate’s durability.
Greater weather resistance — The steel on outdoor structures is vulnerable to the impact of snow, rain, wind and sun over time. Metallization provides a protective coating that creates a barrier between the underlying structure and the elements, which can lengthen the structure’s lifespan and preserve its appearance.
Reduced maintenance costs — Painted surfaces will need repainting periodically to preserve the finish. A metallized surface will not require repainting or upkeep, resulting in lower maintenance costs. Like paint, metallized coatings are available in a wide assortment of attractive colors to meet aesthetic requirements.
