Metal Roofing Galvinum Finish

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.

Metal roofing galvinum finish.

The mixture of zinc and aluminum protects the galvalume metal against corrosion and rust helping galvalume typically last much longer than galvanized steel. The addition of aluminum to the zinc coating differentiates galvalume from traditional galvanized treatments. Galvalume is a long lasting zinc aluminum alloy spangle that offers superior corrosion resistance. Not as shiny as galvanized.

Zinc coated metal exhibits two types of finishes. Galvalume finish utilizes a perfect blend of aluminum and zinc 55 aluminum and 45 zinc to coat a durable steel substrate. With no shine to distract the eye the focus of your project will be on the unique metal roof color. Thermobond provides texture and multi hued colors.

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. Unlike normal galvanizing this metal material is an actual combination of aluminum and zinc to provide excellent protection. These coatings with extra layers of pvdf include more of the fluorite based resin for extra protection of the pigmentation. 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.

Due to the longevity of a standing seam roof you should only consider a kynar 500 paint finish to ensure you paint lasts as long as your material. Galvanizing the metal provides an additional barrier against the elements and produces a white film over the metal from zinc oxidation. Modern ceramic paints allow black metal roofing coatings to reflect 25 or more of the sun s rays propelling this rich finish to the forefront in color selection. Often used to resemble classic aged metal our bonderized and galvalume finishes have a natural real feel that create beautiful contrast agains wood siding or glossy painted surfaces.

And hot dip galvanized steel which has a rough and dull finish. 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. Classic metal roofing systems offers a proprietary powder pvdf called thermobond which is applied and baked on top of the standard pvdf finish. A small amount if silicon is also introduced to the coating to ensure an even and durable adhesion.
