Stone coated metal roof tile use aluminum-zinc plated steel sheet (also call galvalume steel and PPGL) as the substrate, covered by natural stone chips and acrylic resin glue. The weight is only 1/6 of the traditional tile and it is easy to install.
Because the warranty of stone coated roof tile could be up to 50 years and the design are modern, so more and more countries choose it as a preferred roofing material, such as the USA, Canada, Indonesia, Sri Lanka, South of Korea, Nigeria, Kenya and so on.

1. Excellent durability and waterproof
High-quality aluminum-zinc plated steel sheet and natural stone chips coating with acrylic resin glue make stone coated roof tile has superior corrosion resistance and waterproof characteristics. The warranty could be up to 50 years.
2. Light-weight and easy to install
The weight of stone coated metal roof tile is only 1/6 of the concrete or clay tile, only 5.20-6.40kgs per m2. It is easy to transport, store, and install. Averagely a roofer can install 500 m2 every single day.
The cost per square meter of stone coated metal tile is way lower than traditional tiles. And because it's much lighter too, you can save a lot on the roof frame and structure, like the rafters and battens, and save the installation cost too.
4.Noise reduction and heat insulation
The stone granules on the surface are specially made to avoid noise in rainstorm weather and to highly reflect the UV and prevent the temperature under the roof from rising dramatically on hot days.

1. Long Warranty
All Sangobuild stone coated metal roof tiles are made with galvalume steel (Zinc Aluminum coated steel sheet=PPGL). Galvalume steel can last 6-9 times longer than ordinary galvanized steel(Zinc plated steel=PPGI).
Furthermore, the reflective rate for galvalume steel is twice higher than the galvanized steel, so it can better control the temperature under the roof.
Our stone coated roofing tile offer 50 Years' Warranty.
2. No Color Fading
Sangobuild roofing tiles are coated with CARLAC(CL) natural stone chips which are taken from quarries in French. CL also supplies the stone chips to the factories in New Zealand, South Korea, and the USA. The CL granules have been tested that they can well resist the weathering and the extreme UV, and the color will never fade.
3. No Stones Peel Off
The traditional spraying glue will cause the granules to peel off easily. Sangobuild has improved the technology to pouring glue which could avoid the stones peeling off problem very well.
4. Fingerprint Resistance Coating
There is a fingerprint-resistant coating on one side of the galvalume steel which could extend the product's lifespan.
We can make any color for the fingerprint-resistant coating as customized and also could make it on both sides.
