We use Duplex System when make our gates: Galvanized Steel and Powder Coated Paint. When powder paint is applied to galvanized steel, this is referred to as the Duplex System. The Duplex System is the best process used today to protect against any weathering affects of our environment on steel. The powder coating actually increases the life of the galvanized steel. The paint slows the process of at which the zinc is being consumed. Galvanized Steel is iron that has been through a chemical process that protects the steel from rust and corrosion. The steel is submerged in molted zinc at temperatures greater than 800 degrees This process known as galvanizing, permanently bonds the zinc to the steel. The zinc is now a shield for the iron. Powder coating is the technique of applying dry paint to an item. The item(s) are then placed in an stove and heated in temperatures that range from 300°F to 400°F (depending on the powder).When powder coated items are installed correctly and maintained, they should be permanent. Unlike conventional paints, powder coated paints will not peel, chip or crack. Color: Black. Material: Metal.
