Galvanized Nails
What is Galvanized Nails?
Galvanized nails are a special type of nail used in structure. Galvanized nails have undergone a special galvanization process, which involves covering them with a zinc coating in order to form a protective barrier. This barrier also works as a sacrificial anode, which means the coating will dissolve before the metal inside does, if the barrier itself becomes damaged. The protective barrier zinc oxide provides on galvanized nails has many advantages. First, it keeps oxidation from occurring. In this way, galvanized nails are highly resistant to rust and impairment.
Traditionally, the method used to test the effectively of a covering of galvanization is to determine its opposition to a salt spray. Galvanized nails with thin coatings are unable to withstand these types of surface abrasions for long periods of time. Nonetheless, galvanized nails created through electroplating are generally all that is necessary for most residential purposes, though a few precautions should be kept in mind. This will cause the galvanized nails to rust and leave black streaks around the nail in the wood. Instead, mechanically galvanized nails, which are dull gray in appearance, should be used.
