Decoulife Slate is a beautiful natural blue-grey slate sourced from quarries in China. It is well known for its superior strength and durability, and is commonly used as roofing material for prestigious buildings and monuments worldwide.

Due to its premium quality, Decoulife Slate is frequently used in areas with strict building regulations and is an excellent choice for historical buildings and conservation projects. It also serves as an alternative to Ffestiniog slate, a traditional Welsh blue-grey slate that is no longer available.
