What exactly is galvanized steel? What are the benefits of using it on your home? There are many benefits to galvanized steel gutters, let’s discuss.
Steel is a mixture of iron alloys and other elements, most often carbon. Because iron rusts easily, steel alone is not always the best material when it comes to surviving all weather conditions.
Galvanized steel goes through a chemical process that layers the steel with zinc oxides. When steel is submerged in melted zinc, a chemical reaction permanently bonds the zinc to the steel. Because of this, the zinc isn’t exactly a sealer. Like paint would be, but it actually becomes a part of the steel. The most external layer is all zinc, and other layers are a mixture of zinc and iron, with an interior of pure steel. This process is known as hot dipped galvanization. Overtime, galvanized steel does not form a patina and because of this its shine remains.
The extra external layer of coating serves to add protection. This helps them to better resist water, and weather, as well as physical damage. This is the opposite of what galvalume steel offers.
The benefits of galvanized steel:
- Resistant to rust – iron, which is a major component of steel, reacts very easily with oxygen. As well as moisture and will eventually disintegrate. The layer of zinc on the surface prevents the elements from reaching the steel so quickly.
- Resists corroding
- Scratch resistant
- Thermal warping does not occur
- Easier to clean – Chlorine-based bleaches can destroy the oxide layer on stainless steel, but not galvanized steel.
- Durability & lifespan – typically can last up to 15 years (if they are well maintained)
- Durability wise, galvanized steel is the strongest material on the market for gutters.
- Shiny silver look
- Lowest cost specialty gutter material to install
Because of these benefits, galvanized gutters can better resist water, and weather, as well as physical damage. They can be painted over to meet style preferences. This will also help to further increase protection against the elements. Because galvanized steel does not patina overtime, many homeowners prefer it.
The unique mill finish of galvanized gutters often compliments contemporary and modern style homes. In addition, it adds a beautiful rustic look to barns and farm homes.
