In the early stage, communicate with the customer about the brick type, density, and physical and chemical indicators he needs. Once it is determined that the customer's needs can be fulfilled, we plan to start scheduling production, determine the delivery time, and communicate the packaging method. If the size is not the national standard and a grinding tool is needed, the customer is responsible for the cost of the grinding tool. Finally, both parties signed the contract after confirming the order content again and paid the deposit. Complete customer products on time, quantity and quality.
