Galvanized steel is a type of steel that has been coated with a layer of zinc to protect it from rust and corrosion. This process, known as galvanization, helps extend the lifespan of the steel, making it suitable for outdoor and industrial applications. Common uses include construction materials, automotive parts, and household items. The zinc coating acts as a barrier, preventing moisture and oxygen from reaching the underlying steel. If the coating is scratched or damaged, the zinc still provides protection by corroding first, which helps to preserve the integrity of the steel. This makes galvanized steel a popular choice for many projects requiring durability and resistance to the elements.
