Metal Roofing Galvinum Finish

Galvalume finish corrugated metal is one of the most corrosion resistant corrugated materials offered in the architectural roofing and siding panel market.

Metal roofing galvinum finish.

Galvalume finish utilizes a perfect blend of aluminum and zinc 55 aluminum and 45 zinc to coat a durable steel substrate. Galvalume is a long lasting zinc aluminum alloy spangle that offers superior corrosion resistance. What is galvalume roofing material. Unlike normal galvanizing this metal material is an actual combination of aluminum and zinc to provide excellent protection.

Painted metal roof panels typically begin with galvalume and are then primed and painted but galvalume alone looks amazing from many angles it will look nearly white in other angles more of a gray finish. Paint finish warranties are key to understanding the expected longevity of a galvanized or galvalume metal roof. Galvalume metal roof and siding panels are coated with a mixture of zinc and aluminum and siliconized coating to help resist scuffs and fingerprints better than a bare metal product. The carbon fluorine bond one of the strongest known to man is the key to the coating s unsurpassed thermal chemical and ultraviolet resistance.

Combining different metals on a metal roof system can actually lead to interactions that could result in early degradation staining and potential failure of a system altogether. A small amount if silicon is also introduced to the coating to ensure an even and durable adhesion. The addition of aluminum to the zinc coating differentiates galvalume from traditional galvanized treatments. These products are not really mill finish but actually have a low cost clear acrylic coating on the metal designed to protect it during fabrication and installation.

What is galvalume metal finish. Aluminum roofing comes with paint finishes as well and have their own warranties. The secret of fluoropolymer s remarkable properties lies in its molecular structure. The big difference is that aluminum will oxidize chalk if exposed to the elements but the aluminum will not look unsightly and continue on with a rapid oxidation process deterioration rust as steel will.

This coating acts as an excellent protection against corrosion. This superior roofing material also used as siding is actually sheets of steel coated with a composition of 45 zinc and 55 aluminum. As you research metal roofing you may hear about mill finish corrosion resistant galvalume steel. One roofing material that stands above the rest for high quality longevity and durability is galvalume.
