Cold rolled and Hot rolled Galvalum steel

Cold rolled Galvalum is a type of steel product that has been coated with a layer of zinc and aluminum to protect it from corrosion. The cold rolling process involves passing the steel through a series of rollers at room temperature to achieve the desired thickness and surface finish. Galvalume is known for its excellent corrosion resistance and durability, making it a popular choice for a wide range of applications, including roofing, siding, and automotive components.

Hot rolled Galvalum is a type of steel that has been coated with a layer of zinc-aluminum alloy to provide corrosion resistance. This process involves passing the steel through a series of rollers while it is still hot, which helps to bond the zinc-aluminum coating to the surface of the steel. The resulting product is a durable and long-lasting material that is commonly used in construction, automotive manufacturing, and other industries where corrosion resistance is important.
