Spangle and gentle sheen of unpainted galvalume offers a very attractive appearance.
Unpainted galvalume metal roof.
Metal roofs do not need.
Galvalume roofing material combines three of the most important metals used in roofing today steel aluminum and zinc.
It is a trademarked name but many people use it as a generic term to describe a metal roofing product consisting of steel coil coated with a metal alloy.
Manufacturers begin with a carbon steel base sheet that is then continuously hot dipped with aluminum and zinc alloys until it reaches a coating consisting of 55 aluminum 43 4 zinc and 1 6 silicone.
A galvalume metal roof is durable and can outlast asphalt roofs by years.
Galvalume is a sheet steel product covered with an aluminum zinc coating.
Galvanized metal roofs shed more easily than shingles or tiles and this makes them useful in places where leaf acorn and pine and redwood needle buildup is a problem.
The reason aluminum was chosen as the one of the metals to coat the steel was.
Although galvalume metal and galvanized metal sound alike they have quite a few different characteristics and qualities.
Both finishes create stunning looks reinforce metal s strength and add to its longevity.
It will age naturally creating a unique one of a kind metal.
The more unpainted metal is exposed to the elements the more it will take on a life of its own.
This has been proven by actual.
Galvalume has an excellent performance lifespan in bare exposures unpainted panels as well.
Copper zinc stainless steel galvalume or any other unpainted metal roofing material all have their appeal.
Which bring us to the next metal that helps coat the steel zinc.
Product characteristics proven superior corrosion resistance galvalume steel sheet can be expected to provide at least twice the service life of traditional zinc coatings of similar coating thickness under the same exposure conditions.
That alloy is 45 zinc and 55 aluminum and looks similar to galvanized steel but the visible crystals are smaller and close together giving it a smoother appearance.
Most residential grade galvalume metal roofing products like galvanized steel are coated with kynar 500 or hylar 5000 paint finishes.
Aluminum helps prevent corrosion which is highly valuable for a roof that you want to last a long time.
