Galvanized roofing is a type of metal roofing that combines zinc, aluminum, and steel. These three materials have many advantages, including resistance to corrosion, impermeability, and durability. Galvanized roofs are also easier to install and maintain than other types of roofs. Learn more about galvanized roofing in this article. And visit your local building supply store to see what kinds of galvanized roofing are available. Here are the pros and cons of galvanized roofing. A fantastic read!
Galvalume combines steel, aluminum, and zinc
In the early 1900s, Bethlehem Steel invented an alloy that combined steel, aluminum, and zinc and patented the product. Today, more than fifty manufacturers use Galvalume coating to make products that are both durable and aesthetically pleasing. Known by several trade names, Galvalume is used in appliances, framing, and walls. Its durability makes it an excellent choice for many industrial and commercial applications.
Bethlehem Steel was the first company to develop galvalume, an alloy of steel, aluminum, and zinc that provides exceptional protection for iron-based alloys. It is different from galvanized metal, which is made by coating steel with 100% zinc. Galvalume is an alloy of steel and aluminum that contains trace amounts of silicon and aluminum. This material outperforms galvanized steel in both durability and protection.
It is corrosion-resistant
A coating of zinc or aluminum is applied to a metal surface to prevent rust formation. It also inhibits oxidation. This makes galvanized roofing extremely durable. The process of galvanization has made it possible to use steel for decades without experiencing deterioration. A newer alloy of zinc, silicon, and aluminum is called galvalume. These materials have similar corrosion resistance and last for many decades.
Galvalume steel panels are available with a 25-30 year warranty for rust-resistant performance. While these warranties only cover surface rust, they do not protect against rust-throughout corrosion. Galvanized steel roofs do not have a warranty for the substrate and are unreliable in specific climates. However, if your climate is not too harsh, you may want to consider using galvalume roofing panels. These roofs are known for their long life and strength and are also corrosion-resistant.
It is self-healing
In the case of steel roofing, galvanized steel is much more durable than galvalume, a synthetic material with self-healing properties. Generally, Galvalume will remain in pristine condition for five to ten years before rusting occurs. On the other hand, Galvalume roofing will eventually begin to show signs of rust, most notably at nicks and scratches. This is because the rusting isn’t self-healing, but it has spread out from the point of origin.
Fortunately, there are a number of benefits to galvalume steel roofing. In particular, it has a self-healing characteristic, unlike galvanized steel, which is susceptible to rusting when scratched. Additionally, galvalume is a good option for energy efficiency, as it reflects solar radiant heat. However, beware of rusting that is caused by ammonia gas.
It is easier to install
If you’re wondering whether galvalume or galvanized roofing is better, you’re not alone. These materials are both strong and reliable. Both are less expensive than asphalt shingles, but galvalume is generally easier to install. Roofing sheets made of galvalume are more appealing to the eye and can be installed over asphalt shingles or wood underlayment. Galvalume is made up of a combination of zinc and aluminum, but also contains a little silicon. Compared to galvanized steel, galvalume has a more matte finish. Additional info!
