- Steel:
The most common, steel nails are less expensive but unable to stand up well to the elements. (They are designed for interior use). - Galvanized:
These are coated with zinc for resistance to elements and are best suited for outdoor use. - Cement coated:
CC nails are coated with adhesive for better holding power. - Bright:
Since these have no corrosion-resistant finish, they are best suited for interior use. - Other metals:
Many other metals are used to make nails. These materials often stand up well to corrosion and can therefore be used outdoors. - Plastic composite:
These do not rust or stain, and they make stronger connections than metal nails.
