Black Slate Landscaping Stone
These properties help the material withstand long-term outdoor exposure. Our quality control team checks the dimensions and weight of each block. We also conduct random water absorption tests on selected pieces to verify consistency.
Professional Surface Treatment Workshop
Our factory operates a dedicated stone surface treatment workshop with complete processing facilities. The stone is sourced from stable mine supplies and carefully selected before production. Its natural color ranges from dark grey to charcoal black, creating a strong visual effect for outdoor landscapes.
We preserve the original wrinkled texture of the surface to maintain its natural appearance. We also provide different finishing options according to project requirements, including acid washing and flame treatment. Acid washing can enhance the depth of the color, while flame treatment creates a rougher and more rustic surface texture.
During processing, our workers inspect each piece carefully. We do not promise identical patterns because natural stone always has unique textures and variations. Instead, we ensure that every piece meets our quality requirements before shipment.
Black slate landscaping stone features a deep dark tone that brings a modern atmosphere to outdoor spaces. Many landscape designers select it for contemporary gardens and architectural projects.
Strong Physical Performance And Durability
The stone provides reliable physical performance for outdoor applications. Its compressive strength reaches 42 MPa or above, while water absorption remains below 1.2%. The Mohs hardness rating is between 5 and 6.
