When fabricating steel products, it’s also important to consider the finish that needs to be applied to the product. The two most common steel finishes are galvanising and powder coating. Galvanising is the process whereby the steel is submerged is dipped into a bath of molten zinc. The zinc creates a thick layer around the steel, helping to guard against corrosion. Powder coating is a dry process which requires an electrostatic charge in the metal to allow the powder to bind to the surface of the metal. The metal then undergoes a baking process; the heat enables the powder to complete the binding process, forming a protective layer against the elements. While galvanising and powder coating are two very distinct processes, they are both equally good at protecting the structural steel beams and columns from corrosion.
