Abighouse Quality Idea: 1% quality defect is user 100% disaster,
we have a perfect quality control system
We always try our best to select blocks from the same portion in quarry and use the same block to make sure the color consistency of the products.
After cut to size,we will do inspection on the polishing,flatness,thickness,mending and so on.Then we do color selection,mark the serial numbers on
stone.It is our responsibility that never let the unqualified products go out of our factory.
