Feature:
1. Durable: Stone coated metal roofing system has the advantages of heat-resisting, corrosion resisting and ageless.
2. Safe: The unique waterproof, windproof, the installation design, together with the advantages of natural stone and steel, Metal Roofing System can against of strong wind, heavy rain, and hail penetration.
3. Light-weight: Stone coated roof tile is only 1/6 of the weight of normal ceramic or cement tile, which makes it much cheaper to transport and easier to install.
4. The Aluminum-Zinc Alloy Coated Steel offering the superior corrosion resistance.
The use of non-toxic harmless bond, the natural stone and 10 available colors enhances the environmental friendly and stylish advantage.

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 and installation..
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.
PRODUCTION
Our production facility is one of the most sophisticated in the world. The teamwork between our technical and production groups has resulted in many automated systems. These systems are not just responsible for production speed, they also ensure the consistent quality of our finished goods.
Producing a coated metal tile involves four basic steps.
1. metal forming
2. coating
3. curing
4. warehousing
METAL DEPARTMENT
Large coils of Zinc-Aluminium steel are shipped into the factory. The coils are cut and formed into roof tiles and accessories.
COATING DEPARTMENT
The newly formed pieces are sent from the metal department to the coating department. Here they are coated with either high-grade roof paint, or coated in basecoat and covered in stone chips.
CURING DEPARTMENT
The newly coated pieces are then transferred to large ovens where they are baked until the coatings are fully cured and stable.
WAREHOUSING
All the cured parts and pieces are then palletized, wrapped, labeled and prepared for shipping.
QUALITY CONTROL
We employ full time professionals whose sole responsibility is testing and auditing our production process and materials. Adherence to strict guidelines maintains our foremost level of quality.
