Galvanization, named for Luigi Galvani, is a process where a protective coating is applied to steel or iron to keep it from rusting. The galvanization process produces a distinctive pattern called “spangle,” so it is easy to tell when metal is galvanized. But why would you want galvanized metal, and is it a good choice for your metal fences?
How Does It Work?
The galvanization coating on steel and iron is made from zinc, which directly protects the metal from corrosive substances, like acid rain and road salt. The zinc coating also protects the base metal from rusting. The zinc corrodes faster than the base metal, which is the goal when trying to limit rust. If the coating gets scratched, it will sacrifice its anode more easily than the base metal, which also protects the base metal from rusting. The galvanization process is quick and thorough: the metal is either hot-dipped to coat with a thick layer of zinc, electrogalvanized (dipped in a salt and zinc solution that bonds once an electric current runs through) to coat with a thin layer, or dry galvanized (tumbled in a super-heated drum with zinc powder). Whatever the method, the result is that the galvanized coating covers every inch of the metal, so you don’t have to worry that spots were missed.
Why Galvanize Your Fence?
Galvanization is a cheap and relatively easy process that extends the life of almost any metal, so you’ll see it on everything from cars to nuts and bolts. The galvanized metal for your fence will likely cost you more up front than unprotected metal would, but that initial expense will pay for itself in the long run since the coating protects the metal from rust, corrosion, and wear. It is also a cheaper protective coating than most others on the market. Galvanization will also decrease the time and money you need to spend on maintenance and upkeep on your fence. The coating covers every inch of the metal, so you don’t have to worry about bare spots where it will rust, and it is tough enough to stand up to any weather, even the constant assault of sand and salt in a coastal environment. This protection can last up to 50 years, so you’ll be protected, and it could improve your eventual resale value too. The bottom line is that galvanization is added to just about any project where the metal will live outside when it is done, so this definitely applies to your metal fences.
