  • Precision Carving:
    CNC (Computer Numerical Control) machines are used to engrave intricate designs and patterns on stone surfaces. This step is crucial for achieving detailed and consistent decorative elements.

  • Quality Verification:
    Every engraved piece undergoes strict dimensional and quality checks to maintain uniformity across the product line.

  • High-Precision Cutting:
    Waterjet technology provides precise and clean cuts without generating heat, thus preserving the stone’s natural properties.

Professional Hand Processing

Skilled Craftsmanship:
Experienced artisans perform delicate hand processing to refine edges and details that machines cannot achieve. This step adds a unique touch to each product.

    • Surface Refinement:
      Hand polishing and detailed adjustments ensure that the natural beauty of the stone is fully realized.

    • Edge Profiling:
      Stone edges are processed using specialized machinery and hand tools to achieve smooth, uniform edges that enhance both aesthetics and safety.

    • Durability Enhancement:
      Proper edge processing also improves the stone’s resistance to chipping and damage during handling and installation.

Stone With Different Surface Finishing​

About EDG Stone Quality Control Departments

Stone With Different Surface Finishing

Polished and Matte Finishes

  • Polishing Process:
    Advanced polishing techniques create a high-gloss finish that highlights the natural veining and colors of the stone. The polished surface is tested for uniform shine and clarity.

  • Matte Finishing:
    For clients preferring a more subtle, non-reflective look, matte finishes are applied. These finishes are carefully controlled to achieve the desired texture without compromising quality.

Specialized Surface Treatments

    • Antique Finish:
      Through controlled abrasion and finishing techniques, an antique look is achieved that gives the stone a classic, timeless appearance.

    • Acid-Etched Finish:
      Acid washing is used to create a unique texture on the stone surface. This process requires careful control to ensure consistent results and durability.

    Before the final assembly, stone slabs are meticulously arranged to form aesthetically pleasing patterns. Layout planning considers color variations, grain direction, and overall design harmony.

  • Quality Checks:
    The layout process includes verifying that patterns align perfectly and that there are no visible seams or mismatches.
