Flamed Finish Royal Grey Diamond

•High temperature flame spraying

Product Features

Royal Grey Granite with a flamed finish combines the strength of natural granite with a raw, textured surface created through high-temperature treatment. This process causes mineral crystals to fracture unevenly, producing a non-slip surface with a rustic, natural appearance. The result is a versatile stone ideal for outdoor or high-traffic spaces that require both performance and aesthetics.

✔ Natural Non-Slip Texture – Flamed surface delivers superior grip and a rugged, organic visual.
✔ Durable & Weatherproof – Withstands heavy use and outdoor exposure without fading or cracking.
✔ Rustic Visual Appeal – Offers a more natural, understated alternative to polished finishes.

1. Basic properties

Royal Grey Diamond Granite Flame Surface is made of high-quality Royal Grey Diamond Granite and processed by high-temperature flame process. Relying on the hard texture of natural granite and the unique processing effect of the flame surface, it has become a high-quality material with both practicality and beauty in the field of architectural decoration, suitable for multiple scenes with requirements for anti-slip and texture.

2. Process characteristics-flame surface treatment

By spraying the stone surface with high-temperature flame, the crystals inside the stone are heated unevenly, expanded and cracked, forming a natural and rough concave and convex texture. The surface presents an irregular cracking effect, and the touch is rough and granular. It not only retains the natural texture of granite, but also gives it anti-slip and wear-resistant practical properties. Different from the smooth and delicate glossy surface, it is more simple and natural.
