Metalizing objects, in which components, surfaces, or structures are coated to give them a metallic finish, has been done since the 1800s. Metalizing can serve different purposes, from providing a slip-resistant surface to creating a protective coating that helps objects last longer and withstand corrosion. AZZ’s environmentally-friendly metalizing processes are performed at their Tulsa, Oklahoma facility and via their mobile metalizing service. While many materials can be used for metalizing, AZZ’s processes use zinc, aluminum, 85/15 zinc/aluminum, ceramic core (an anti-skid product with corrosion protection) and iron carbide (a hot-dip galvanize-friendly anti-skid product).
Metalizing is typically used to extend the life of metal, concrete, wood, and some plastic surfaces. With corrosion protection designed to last for decades, it extends the life of both galvanized and non-galvanized structures. As a global provider of galvanizing, welding solutions, specialty electrical equipment, and highly engineered services, AZZ has a strong reputation for providing customers with the highest quality metalizing processes and responsible customer service. AZZ’s applications range from bridges and highways to petrochemical plants and solar farms—which is why we are in a unique position to explain this fascinating process and why you should consider it for your next project.
Metalizing occurs when a thermal spray coating process is used to coat metal on product surfaces for protective, decorative, or functional purposes. AZZ’s environmentally-friendly process begins with an abrasive surface cleaning. This is followed by a thermal-sprayed coating of zinc, aluminum, or zinc-aluminum alloy applied at our facility—or in virtually any environment. Thermal spraying techniques use electricity (plasma or arc) or a flame to heat the material, and then coat the target.
Metalizing provides a thicker coating of metal than electroplating, or physical and chemical vapor deposition. Metalizing can be very beneficial for avoiding corrosion; metalizing with zinc and aluminum, for example, provides steel with corrosion protection that lasts decades longer than paint alone. There is no size limitation to metalizing, meaning it can be used for bridges, locks and dams, piers, and other large facilities. There is also no dry or cure time, which significantly increases fabricator throughput. And since this is a low-temperature process, never exceeding 250-300°, there is practically no risk of weld damage or steel distortion from the process.
