High Quality Prime Hot Dipped Galvanized Steel Coil
What is it?
Galvanized steel coil is steel that has gone through a chemical process to keep it from corroding. The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily. The coating also gives the steel a more durable, hard to scratch finish that many people find attractive. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component.
One of the most common ways of making steel resist rust is by combining (alloying) it with a metal that is less likely to corrode: zinc. When steel is submerged in melted zinc, a chemical reaction permanently bonds the zinc to the steel. Therefore, the zinc isn't exactly a sealer, like paint, because it doesn't just coat the other metal; it actually permanently becomes a part of it. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel.
Zinc protects steel in two ways. First, it is highly resistant to rust; iron, a major component of steel, reacts very easily with oxygen and moisture and will eventually disintegrate. The layer of zinc on the surface prevents those elements from reaching the steel so quickly. It also develops a patina — a layer of zinc oxides, salts, and other compounds — that offers further protection. Zinc is also extremely durable and scratch resistant, and has a satiny appearance that many find attractive.
The outer layer also protects the steel by acting as a "sacrificial layer." If, for some reason, rust does take hold on the surface of galvanized steel, the zinc will get corroded first. Even in areas where the surface is scratched or damaged, the surrounding zinc will still corrode before the steel does. The lifespan of galvanized steel varies, but industrial steel with a 3.9 mil (0.0039 inches or 0.09906 mm) thick coating can last more than 70 years without maintenance under average conditions.
Uses
Galvanized steel can be found almost everywhere. Many individuals live in steel frame houses, and buildings are often made with galvanized steel roofs. There are multiple steel parts in cars that help protect them from the weather, and it's used in many marine applications due to its ability to withstand the salt and the elements. Besides being inexpensive, durable and effective, this metal is also popular because it can be recycled and reused multiple times.
