The panels are structural grade steel, with a minimum tensile strenght of 37ksi.  They are rigid enough to tolerate reasonable loads, while allowing profile designs without the risks of cracking or significant elastic recovery.


Protection for the rigid steel material is achieved when the steel passes through a bath of molten aluminium-zinc alloy.  This coating combines the protection and strength of bath aluminium 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 aluminium zinc alloy steel have captured exposure data indicating corrosion protection for the underlying steel for more than 50 years in most environments. Thatchtiles carry a 20 year warranty on the steel substrate and a 10 year warranty on the top coating. (All warranty’s are subject to terms and conditions).


An acrylic coating is applied to both sides of the panel immediately after the application of the aluminium-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.


The basecoat is formed by applying a custom designed acrylic resin binder.  This specially formulated paint coating is made in two colours that will blend with the various stone granule colours.  The basecoat serves two functions:
It serves as an adhesive that bonds the stone granules to the base steel.
It protects the underlying material from water.
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 water-based paint.



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 colours. These ceramic coated granules are sized and applied in such a way to insure maximum coverage of the basecoat; therefor, allowing another layer of protection against water erosion.


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.
