Steel parts rust unless steps are taken to prevent or slow down the corrosion reaction. One such approach, galvanizing, involves applying a zinc coating on the steel surface. Batch galvanizing involves dipping fully formed parts into a molten zinc bath. A wide variety of parts and sizes, from small fasteners to long beams and poles, undergo galvanizing in this manner. This approach works best on thicker parts that will not distort from the heat of the zinc bath, and on parts where the costs of the extra manufacturing step and associated handling are justified.
