When steel nails are dipped in a zinc acidic bath, a thin layer of zinc is left behind. Zinc plating or electro-galvanization.There are two different ways in which zinc is typically applied: While eventually the zinc will wear through, the rusting is delayed. ZincĪ layer of zinc over steel will slow corrosion. Note that if a nail is described as “bright,” that means it has no coating and is typically intended for indoor use. Just as the materials used to make nails can improve their performance under certain conditions, the same is true of some coatings that are commonly used. For example bronze nails are often used in the construction of boats while iron nails are still produced, but they are mostly used for the restoration of historic buildings. Some specialty nails are made of other metals, though they are not common in home construction. There are some rare situations where brass nails may be preferable over galvanized ones as the zinc in galvanized coatings may react with certain materials, for example, the copper in copper pipes. Given their cost, they are generally only used in houses when they will be exposed and they provide a decorative accent. This alloy of copper and zinc does not rust and so it has long been used on ships. They are more expensive than other options, but given that they can last for decades, they may be a better value over the long run. These nails are most often used on roofs as they are especially durable and resist the corrosive effects of pollution more than galvanized steel nails. (The zinc in galvanized nails will react with those woods, making aluminum a good alternative.) Copper This is another good option for outdoor use and is used to install aluminum siding and often with cedar and redwood. Carbon steel: The high carbon content of this steel makes it harder and is used for masonry nails.If steel nails are going to be used outdoors, you’ll want either stainless or galvanized ones. Galvanized steel: Galvanized steel is dipped in zinc, which provides a protective layer against corrosion.Stainless steel: The addition of chromium to steel helps it resist corrosion, though it can also reduce the gripping effect of the nail.Most nails are made of steel, with several different options besides untreated steel. There are a few different metals commonly used to make nails. In addition to different nail shapes, the different materials used to make nails and their coatings (or sheathings) make them best suited to particular conditions and situations. $75.00 USD | 1H 53M Preview Course Nail Materials and Coatings
