Material Composition----Panel Layers
1)Steel The panels are structural grade steel, with a minimum
tensile strength of 37ksi. They are rigid enough to tolerate
reasonable loads, while allowing profile designs without the risks
of cracking or significant elastic recovery.
2)Aluminum-Zinc Alloy Coating Protection for the rigid steel
material is achieved when the steel passes through a bath of molten
aluminum-zinc alloy. This coating combines the protection and
strength of both aluminum and zinc. A significant benefit of the
zinc component is its ability to protect exposed areas such as cut
edges, drilled holes and scratches. Developers of the aluminum-zinc
alloy coated steel have captured exposure data indicating corrosion
protection of the underlying steel for more than 50 years in most
3)Acrylic Priming System An acrylic coating is applied to both
sides of the panel immediately after the application of the
aluminum-zinc coatings. We developed this priming system in
association with our steel suppliers to provide a uniform substrate
that enhances the adhesion of subsequent coatings.
4)Basecoat; The basecoat is formed by applying a custom designed
acrylic resin binder. This specially formulated paint coating is
made in two colors that will blend with the various stone granule
colors. The basecoat serves two functions:
----a)It serves as an adhesive that bonds the stone granules to the
----b)It protects the underlying material from water and UV light.
The basecoat’s adhesion process is found in its excellent ability
to adhere to both the granules and the underlying acrylic priming
system. We achieve optimum UV resistance with the use of a pure
acrylic resin; the strongest polymer capable of being made into a
5)Ceramic Coated Stone Granules A protective coating, as well as an
attractive appearance is provided by stone granules. They further
enhance the resistance to UV light while providing an array of
colors. These ceramic coated granules are sized and applied in such
a way to insure maximum coverage of the basecoat; therefore,
allowing another layer of protection against water erosion.
6)Overglaze An acrylic overglaze is applied as a final coating that
gives the granules a semi-gloss appearance. This tough, thin,
acrylic finish bonds to the granules and encapsulates them with a
coating that enhances the panel’s resistance to physical damage.
