Products Description :
Product introduction Colorful Stone Coated Metal Roofing, based on Al-Zn (known as Zincalume or Galalume steel) steel and coated with high quality pressure-shaped stone, is the stylish and best construction material for roof. The raw material is a steel substrate coated on both sides with an aluminum-zinc alloy. The composition of the coating is: 55% aluminum, 43.4% zinc and 1.6% silicon. The excellent corrosion resistance of the material is a result of the properties of the two metallic substances: the barrier effect of the aluminum present on the surface of the coating and the sacrificial protection of zinc. Product Features Class A fire resistance Wind resistance up to 260kph Hail Resistance 6.35cm Impact resistance, superior durability 50 years warranty Controlled quality to ensure accurate size and dimensions Light weight to enhance cost effectiveness and earthquake impact Leakage proof More than 80% recyclable materials Easy Installation Low or no maintenance

8 FAQS
Q: Are stone coated metal roofs noisy when something drops on them?
A: No, the gravels on the surface of our tiles deaden the sound of the rain and even hail unlike a non-stone coated metal roof.
Q: Is a stone coated metal roof hotter in the summer or colder in the winter?
A: No, many customers report a reduction in energy costs during summer and winter months. Also, a SUNSTONE ROOF can be installed over an existing roof, providing additional insulation from temperature extremes.
Q: Is a stone coatef metal roof dangerous in weather with lightning?
A: No, metal roofing is not only an electrical conductor but also a noncombustible material.
Q: Can I walk on my SUNSTONE Roof?
A: Absolutely, SUNSTONE roofs are made of 26-gauge steel at most and designed to withstand the weight of people walking on them.
Q: How do SUNSTONE roofs withstand an earthquake?
A: Very well. A metal roof usually weighs less than half of a typical composition shingle roof.
Q: Is a metal roof hotter in the summer and colder in the winter?
A: No. Many customers report a reduction in energy costs during summer and winter months. Also, a SUNSTONE roof can be installed over an existing roof, which creates even more insulation from temperature extremes.
Q: Is a SUNSTONE ROOF System more expensive?
A SUNSTONE roof offers more value for your money. With a minimum 30 years' life expectancy, you would have to purchase and install 2-1/2 shingle roofs for the cost of one SUNSTONE roof. Like most products you buy, "you get what you pay for." A DECRA roof offers more for your money. Itís no bargain to put two roofs on your house because the first one was "cheaper" and subsequently failed. SUNSTONE is also quite durable because the aluminum-zinc alloy coated steel enhances the superior weathering and corrosion resistance of each roofing panel.
Q: Is a SUNSTONE ROOF System warranted?
A: The best in the Asian industry. SUNSTONE Roofing Systems carry a 30-year warranty including 160 mph windproof and hail penetration for any size hail and manufacturing defects - including excessive granule loss.
Q: What is the best reason to buy a SUNSTONE ROOF System?
A: Well, we've given quite a few reasons, but the best reason is our success in the industry. As the newly booming stone coated steel manufacturer in China, our products have been proven around the world in more than 3 continents with competitive prices and good quality.
Q: Is water run-off from a metal roof potable?
A: Yes, the water run-off from our products meets the World Health Organization Standards testing. However, rainwater is variable across regions; atmospheric conditions should be considered in actual use. Water collected during the first or second rain fall after extended dry periods can be contaminated by dirt accumulation.
Q: Does granule size matter in the longevity of the product?
A: Deterioration of the coating takes place when there is exposed, uncovered basecoat; granule size- smaller or larger- does not ensure better coverage.
Q: Is a metal roof only for commercial buildings?
A: No, SUNSTONE's product profiles and attractive ceramic stone granules do not resemble the standing seam roofs of the commercial industry; they add value and curb appeal to any roofing installation.
Thickness: 0.4mm, 0.45mm, 0.5mm, and the longer sizes are available. The design with anti leaking is available

Professional Knowledge of stone chip caoted roof tile
Stone Chip Coated Roofing Tile?
Sunstone STEEL ROOFING TILE is pressure formed from Galvalume steel to have the appearance of individual roofing tiles. There are seven tile impressions formed horizontally into one panel. Each panel is profiled to form an extremely strong overlapping and interlocking structure. Plus, it is coated with an acrylic resin, an acrylic base adhesive, a natural stone chip, as well as, a clear acrylic overglaze in order upon the top side of the Galvalume steel, So, it provides a long life span, besides strength, durability and beauty.
Galvalume is a registered trademark it is coated with an alloy composed of Al 55%, Zn 43.4%, Si 1.6%.And, it has a superior long term corrosion resistance ability. The combination of the sacrificial protection of zinc with the barrier protection action of the aluminium together provides a superior performance level to galvanized coatings in almost all sorts of varied environments.
TECHINICA INFO. ---->>>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 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 base steel.
----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 water-based paint.
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.
