For colored slabs/ tiles: polishing +85 in gloss meter

There should be no grinding wheel marks on the polished face

Flaming:

Flaming will be uniform throughout the slabs/tiles and brushed evenly on slabs after flaming

Thickness:

+/-1.0mm in tolerance for slabs

+/-0.5mm in tolerance for tiles

Diagonal Out:

+/- 0.5mm in tolerance for tiles

Flatness:

If length <= 400mm, flatness tolerance: +/-0.2mm

If 400mm < length < 1000, flatness tolerance: +/- 0.5mm

If length >= 1000mm, tolerance: +/- 0.8mm

Length and Width:

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

Front Edge Defect:

Unpolished Side:

The unpolished side of the slab/tiles should be flat and smooth.

Crack Looks Treatment:

If slab/tile have crack looks (not the real crack, like paper was foddered but not tear down), please treat it.

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.
