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.

1.Raw materials Galvalume steel


All San-gobuild@ roof products are manufactured from galvalume steel which has shown in tests to last 6-9 times longer than ordinary galvanized steel roofing products.

2.Color Chart


All San-gobuild roof tiles are coated with natural stone chips, volcanically formed and taken from quarries in French.
These coatings add natural beauty to the roof and a hard layer of protection from the weather. Being of natural stone, the vibrant color is protected against the extreme UV of the African sun and will never change. 100% fadeless.

1. Outstanding Lifetime Value

Stone-coated steel roofs have a far longer lifespan than traditional materials. Standard asphalt shingles have a lifespan of 15-18 years, where Sangobuild Roofing Systems have a lifespan and warranty of 50 years.

2. Durable and Hard-Wearing in Extreme Conditions

Stone-coated steel roofs provide prolonged protection in the harshest of conditions.
At Sangobuild, we know that our roofing system needs to be capable of withstanding extreme weather conditions across the world - high winds, fire, heavy rain, snowfall, hail, earthquakes, and hurricanes.For this reason, our roofing systems go through rigorous weather condition testing, allowing us to meet all building codes, even in the harshest weather conditions.
Our products are designed to be used anywhere in the world.

3.Profiles and Colors Consumers Love

Available in a wide variety of profiles and colors, a stone-coated steel roof suits any house and design type, whether it's a new and contemporary style or a heritage home.

The huge advantage is that although they can be designed to look like more traditional roofing materials, they won't burn, curl, split, crack or rot as traditional materials do.

4.Sustainable

During the installation of a stone-coated steel roof, there is less waste that ends up in landfills, as all steel wastage from the installation process can be recycled.

With innate heat absorption characteristics, stone-coated steel roofs help to mitigate the 'heat island effect' - a phenomenon now known to be a key contributor to greenhouse issues in urban areas.

Stone-coated steel roofs are 100% recyclable, unlike asphalt which takes over 100 years to break down in a landfill.

And with Sangobuild, our roofing system meets the World Health Organization standards for water run-off (asphalt begins to
bio-degrade after 6 years making water run-off not only unusable but chemically dangerous).
