Stone-coated metal roofing tile uses Alu-zinc alloy steel with multiple protective films as the substrate, pressed under the mold with well-developed technology, combining with colorful basalt granules as the surface, to become the best roofing tile materials.
High technic stone coated metal roofing tile combines multiple protective films galvalume steel, which contains 55% of aluminum, together with the acrylic base layer, basalt granules layer, and also acrylic top layer, to become one multiple layers of roofing tile. It makes up the defects of other roofing materials such as PPGI sheets etc. Because of its long life, beautiful appearance, excellent durability, convenient installation, environment-friendly, economic, and easy overlapping construction as well, stone coated metal roofing tiles enjoy great popularity worldwide.
As pioneers in product innovation, research and development is at the heart of what we do, and it's led to our advanced manufacturing processes and products. With this in mind, Sangobuild panels are first pressed and cut into dedicated panel sizes from premium coils of high-quality steel in our factory. From there, 300 metric ton presses create uniform panels in our signature eight-layer process.
This dedicated process includes the application of Zincalume based steel on both sides; priming on both sides; application of an acrylic base coat; the natural stone granules; and then it's followed by a pure acrylic over-glaze.
Once oven baked and hardened, this process offers one of the most durable and reliable roofing systems on the market.
