Are you looking for a perfect metal roofing sheet? The most used are Galvalume and Galvanized, here are a few top differences listed that will help you to make an ideal choice according to your usage and budget.
-
Originated
Galvalume is a trademark name invented in 1972 by Bethlehem Steel. It is used to describe a metal roofing product.
-
Definition
Galvalume is a roofing sheet that has a coating of zinc, silicon, and aluminum. All these coatings protect the metal and are the primary form of the steel made of oxidation.
It protects the base metal and sacrificial metal coating. -
Composition
Galvalume is designed with a combination of zinc, silicon, and aluminum. The composition using these 3 elements in a Galvalume coat is 55% of aluminum, and 43% zinc, with a very low amount of silicon.
Galvanizing is 100% zinc. It is less enhanced in comparison to the Galvalume ability of protection.
-
Usage
Galvalume is used for outdoor roofing as a metal panel mainly for iron-based protection and is rustproof.
Galvalume coating lets it stay protected and is a better resistance in nature in comparison to carbon steel.
The composition of aluminum and zinc helps to be protected from the natural calamities.
Since zinc is the composition, it is comparatively more oxidized than steel.
It has its capacity of resistance when exposed to ice, rain, and snow.
Galvanization used to protect from electric shocks in the 19th century.
It was invented in 1836, and the process of coating steel by dipping it in molten zinc after first cleaning it was used.
Galvanizing is widely used for the protection from corrosion and is a popular roofing sheet. It has a thin zinc coat base metal which helps you to protect from the natural surroundings like water, sun, etc.
Its coating protects the base metal.
It keeps protected from the maintenance and is comparatively less oxidized because it is made of zinc only.
Because of the single metal composition, it is cost-effective.
It is effectively prevented from corrosion.
