The advantages of color metal tile

1. Beautiful appearance—texture and strong stereoscopic impression of natural stone , various colors and styles, good effect in decorating the buildings.

2. Durable—base material is high-strength, high rotproof Al-Zn coated steel and its rotproofness is 3-6 times higher than galvanized steel; the surface material is weathering natural colorful stone chips or inorganic pigments dyeing natural gravel and water-based acrylic resin. Life cycle of product is up to more than 30 years.

3. Light weight—1/6 weight of clay tile or cement tile to reduce the load of the building and the construction costs, easy to transport and repeated construction and installation.

4. Constructing simply—easy to be bent, cut, installed simply and fast, even in low temperature.

5. Energy-efficient and eco-friendly—1.4-7 times higher than the common roofing materials in heat-reflective rate to save energy; no harm to human and environment in eco-friendly materials
