They get their name from a process they undergo called galvanization.
Why are roofing nails zinc coated.
Galvanizing is zinc coating.
Galvanized nails undergo a process that involves coating them with zinc to protect them.
Apart from the protection the barrier also saves the metal from being damaged as the coating would dissolve before the metal.
Generally nails are finished using a hot dip galvanizing method meaning they are immersed in a bath of molten zinc.
Galvanized nails are used mainly in construction specifically roofing.
If the nails are shiny it s just a good even coating.
Zinc unlike other metals will not rust so you wrap the nail with a coat of zinc to prevent rusting.
You don t want stuff falling off your roof so you don t want the nails to rust.
This process adds a protective zinc coating to the nail that prevents rusting and corrosion.
It is an industry standard to use galvanized nails for roofing.
It protects the steel in the nails from rusting since zinc is sacrificial to the steel in the case of corrosion.
Another kind of classification for roofing nails is by size.
Galvanized roofing nails are steel nails that are zinc coated.
This process is commonly known as hot dip galvanizing.
Before you head out to the hardware store to buy galvanized nails for a special project take a look in your toolbox you might have galvanized nails and not even know it.
They hold up better against rust and they can also be used for asphalt shingles.
The coat of zinc is smoothly applied through electroplating which galvanizes the nail through an electrical.
The cost of nickel plating nails for a roof would be incredibly expensive.
