  1. QA/QC Introduction
    Our Quality Control Department is responsible for quality testing of all stone raw materials and finished products. In addition, we also welcome clients to monitor product quality by either personally visiting our production areas or employing third party independent inspection companies. Each order will be followed and monitored from beginning to end by experienced QC inspectors to ensure quality standards and punctual delivery.

  2. Slab & Tile Production Requirements:
    Granite should be grade 1 quality, and the finish as follows:

    1. Polishing: Polishing will be uniform throughout the slabs/tiles and in gloss meter reads:
    For black slabs tiles: polishing +95 in gloss meter
    For colored slabs/tiles, polishing +85 in gloss meter
    There should be no grinding wheel marks on the polished face.

    2. Flaming: Flame will be uniform throughout the slabs/tiles and brushed evenly on slabs/tiles after flaming.

    3. Thickness: (Between different pieces) Needs to be consistent and +/- 1.0mm in tolerance for different slab; and +/- 0.5mm on the same slab; +/- 0.5mm in tolerance for each tile(12”x12”x3/4”).

    4. Flatness (On the same piece): 
    If length <= 400mm,flatness tolerance: +/-0.2mm
    If 400mm < length < 1000, flatness tolerance: +/- 0.5mm
    If length >= 1000mm, tolerance: +/- 0.8mm

    5. Diagonal: +/- 0.5mm in tolerance for tiles.

    6. Length and Width: +/- 0.5mm in tolerance for tiles and slabs (not apply to the random edge slabs).

    7. Unpolished Side: The unpolished side of the slab/tiles should be flat and smooth.

    8. Crack, Edge Defect, Corner Defect: Not allowed for slabs and tiles.

    9. Surface Treatment: If it is possible, treat the slab/tile surface after it has been polished. So there is no little dent. This treatment is not required, but is recommended.
