The coating also gives the steel a more attractive durable finish which is hard to scratch. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component. Hot-dipped galvanization is the most common method used. A variation, continuous sheet galvanizing, runs it through the molten zinc but tends to leave a thinner layer of the protective metal. Painting and spraying don’t impart the strong bond of hot-dipping. While electro galvanizing or electroplating uses electricity to create a bond; it, too, results in a thin layer of zinc. Galvannealed Steel – specialized steel produced by hot-dip galvanization followed by an immediate in-line annealing that imparts a very fine greyish matte finish. The coating doesn’t flake off when formed, stamped, or bent. The matte finish acts like a primer, allowing paint to easily adhere, and is very rust proof. With good paintability and long, reliable, service life, it finds extensive use in automotive, signage, electrical equipment, and other applications requiring these characteristics. GALVALUME® Steel Sheet – is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot-dip process. The nominal coating composition is 55% aluminum and 45% zinc. A small addition of silicon is included in the coating alloy to ensure good coating adhesion to the steel substrate when the product is roll-formed, drawn, or bent during fabrication. The coating offers the barrier corrosion protection of aluminum and the galvanic protection of zinc; it lasts a long time; provides cut-edge protection along sheared edges; outlasts a galvanized coating of comparable thickness; while maintaining a bright finish. As the preferred product for long-term resistance to atmospheric corrosion, it is the preferred material for roofing. Aluminized steel-is steel which is hot-dip coated on both sides with aluminum-silicon alloy, giving a tight metallurgical bond between the steel and its coating. It exhibits better behavior against corrosion and keeps the properties of the base material for temperatures lower than 800 °C (1,470 °F). Commonly used for heat exchangers in residential furnaces, commercial rooftop HVAC units, automotive mufflers, ovens, kitchen ranges, water heaters, fireplaces, barbecue and burners.
