Galvalume Steel Sheet and Galvanized Steel Coil
Galvalume steel sheet is a carbon steel sheet laminated with an aluminum-zinc alloy. Also known as Zincalume, this product is protective against corrosion in many conditions, which makes it ideal for roofing, siding, building components and architectural panels.
Strong, yet lightweight, Galvalume wont crack or peel when subjected to weather. Galvalume consists of 55% aluminum, 43.4% zinc and 1.6% silicon over the base metal. This coating is applied during a continuous hot-dip process. AZ40, AZ50, AZ55 and AZ60 translate to the coating thickness of .40, .50, .55 and .60 ounces per square foot, respectively.
Dragon Metals Trading offers both bare and pre-painted Galvalume. Colors are perfectly matched to your company’s specifications. We provide paint and material warrantees and they vary based on paint systems and product coating.
While Galvalume has excellent durability in many settings, it should not be used adjacent to concrete or mortar. Due to the high alkaline content in these environments, bare and painted Galvalume rapidly corrode.
Galvanized Steel and Galvanized Steel Coil Products
Galvanized steel products are some of the most prevalent types of steel products produced in the world. It refers to steel that has been coated with zinc to create a chemical bond to fight against corrosion. Galvanized steel is widely used in a variety of applications because its superior resistance to corrosion ensures a long lasting product.
Flat-rolled Galvanized steel sheet is carbon steel that is immersed in a bath of molten liquid that consists of at least 98% pure zinc. This “hot-dipped” process allows the zinc to chemically bond to the iron in the flat-rolled steel to create an alloy that is ductile yet durable against corrosion. G-30, G-40, G-60, G-90, and G-100 denote the most common zinc coating weights of 0.30, 0.40, 0.60, 0.90 and .100 ounces per square foot, respectively. Different zinc coating weights are suitable for different environments and the amount of corrosion protection required is dependent on the specific end-use of the material.
Dragon Metals Trading offers bare to paint, acrylic coated, chem-treated, and pre-painted galvanized steel. We work with each customer to ensure that the finished coating meets their specific requirements. In addition, we provide regular spangle, minimum spangle, and no spangle and any bare steel can be skin passed to ensure a smooth, consistent appearance. All of the aforementioned specifications can be customized for every order.
Pre-painted steel is created by applying a coat of specially formulated paint to flat-rolled galvanized or Galvalume steel on a continuous coil coating line. Pre-painted steel combines the corrosion resistant qualities of coated steel with a beautiful, colorful, outer layer that transforms any setting where it is utilized.
Pre-painted steel is often referred to as a duplex coating because it doubles the sum of the corrosion offered by steel and paint alone. Not only does adding paint to bare steel extend the life of the panel, but the durability of the panel allows it to be roll-formed, slit, or stamped without losing any of its anti-corrosion properties. Pre-painted steel is used in a variety of applications such as roofing, rainware, doors, panels, and appliances.
Dragon Metals Trading Companies works with a variety of paint and coil-coating companies to offer 10, 20, and 40-year paint warranties in polyester (PE), silicon modified polyester (SMP), and polyvinylidene difluoride (PVDF) paint systems. We will utilize your existing color chart to ensure that your custom colors are honored.
