Since Quartz countertop is better than Granite Countertop, why America Contractor still choose granite countertops?
(1) The Granite countertop industrial in China is more than 10 years, so every Contractor from America have stable supplier for Granite Countertop in China.
(2) Quartz Countertop have to use large slabs to make Quartz Countertop, if Chinese factory can not control the wastage, they can not lower the cost (we concentrate on the quartz countertop, and have a team to control the wastage for every Quartz Countertop projects by AUTO CAD before Cutting by CNC Machine)
(3) Quartz Countertop industry start in Chinese for just a few years, lots of Quartz factory in China do not have big work shop to make Project Quartz countertops.
(4) The wholesales Quartz slabs market in China is booming, so most of the Quartz factory in China concentrate on Slabs, this make Countertop client (America Contactor)Feel frustrated in the delivery of time (Delivery time is the credit and life for every Contractor)
(5) The quartz factory in China do not find technician to make countertop (as the factory do not have regular orders for Countertops),So now most client need professional Quartz Countertop factory
(6) To tell if a factory is professional is to see their packing, Labeling on the every piece Countertop, marking on every crate.
