What is Galvanizied Steel? - Expert Sheet Metal Las Vegas
Galvanized steel is formed via a hot-dipped galvanizing method which coats steel with a light zinc layer. The steel is then taken to a molten bath of zinc at extreme temperatures of approximately 860 °F (460 °C). When disclosed to the atmosphere, zinc and oxygen form zinc oxide, which with carbon dioxide forms zinc carbonate, a tough material that prevents corrosion in many circumstances, protecting the steel from the elements. Galvanized steel is generally used where rust resistance is required.
Hot-dipping galvanized steel results in a metallurgic bond between steel and zinc with a range of distinct zinc-iron combinations. The resulting coated steel is used just as much as uncoated. Galvanizing steel may be welded; however, exercising caution is required around the remaining fumes of zinc. Galvanized steel can be suitable for 392 °F (200 °C) applications. Temperatures above the aforementioned level will result in the peeling of the intermetallic layer at the zinc. Our steel is ordinarily used for HAVC, roofing and duct purposes (interior and exterior).
