Alston

A deep, profound light grey defines these granite risers, sourced from selected global deposits. This granite presents a uniform, light dark grey hue with a fine to medium crystalline structure that occasionally reveals subtle mineral reflections when caught in the light. The fine to medium grain structure delivers exceptional hardness and strength, making these risers ideal for stair construction and architectural detailing. The thermal flaming process creates a uniform, textured surface that enhances the stone’s natural beauty while ensuring safe footing in all conditions. Highly durable with outstanding frost resistance, this granite performs beautifully in all climates. Bring timeless elegance, dramatic contrast, and enduring performance to your stair project with Alston Granite risers.
