How do I know L & Z Stone granite is high quality?
A. L & Z Stone supplies only first quality material. The quality of the material is determined by measuring different parameters of a granite product through the entire production process: · Mining – L & Z Stone’s granites are mined utilizing modern methods. Some mines still use dynamite or blasting methods to reduce cost, but this also damages the granite. The shock wave created by the blast will cause invisible hairline cracks which will result in the stone cracking at some later time. · Cutting – L & Z Stone’s granites are cut by using water as coolant to ensure a lifetime guarantee on the quality of the product. · Dimensions – Product dimensions are controlled within the stipulated limits in ASTM standards. Tiles are calibrated to ensure their thickness is uniform. Gauging is done to ensure the tiles are square. Beveling is done to produce a smooth edge on the tiles · Inspection: Inspection is done at different stages of the manufacturing process and the products are segregated for
