The characteristics of colorful-stone coated metal roof tile
- beautiful appearance: with the natual stone texture and strong
stereoscopic sensation, and a variety of shapes, varied colors of
tiles, have extremely good beautification effect the buliding
- longlife time :adopt hige strength ,high corrosion resistance
aluminum zinc alloy steel plate, its corrosion resistance is 3-6
times than the corrosion resistance of galvanized steel , the
surface material by weathering of natural stone particles or
inorganic pigments dyeing natural gravel and water-based acrylic
resin, products life up to more than 30 years.
- lighter weight: only equivalent material ,cement soil of 1/6, can
reduce the load of the building,and it can reduce the cost of
project, For the roof ,easy to transport and repeated construction
- construction simole: to bending, cuting ,easy installation,simple
,low temperature season may construction
- energy conservation and environment protection:the heat reflective
rate is 1.4-7 times than average roofing material ,easy energy
saving ,using environment protection material ,and no harm to
people and environment.
TECHINICA INFO. ---->>>Material
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 environments.
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.
