How is slate formed?

    Slate is known as a metamorphic rock because its formation originates from an existing rock known as shale. That is, the originating rock shale changes its mineral composition by heat and pressure, a process known as crystallization. This new form of rock slate may consist of many minerals such as, mica, chlorite, and quartz. Metamorphic rocks are known to be a harder material than most other types of rocks, hence, giving slate a characteristic known to be more resistant to weathering and erosion. This is what makes slate such an attractive product for applications that will endure harsh conditions.

      It is important that the material being extracted from the quarry meets high standards. The American Society for Testing and Materials International (ASTM) has tested our product in various categories such as Absorption, Strength, Abrasion resistance, Acid resistance, and Coefficient of friction. The results were high marks in all categories, reflecting competitive quality in our product.
