Apart from the advanced and efficient repairing techniques, ample supply of high quality parts support is another pre-requisite for excellent after-sales services. In order to achieve this, a large operational warehouse was built to ensure the abundant supply of parts. The company has a 60,000-square-metre warehouse that stores more than 27,000 items of parts. With the ISO system guidelines, the storage and flow of parts items are more standardized to ensure timely and consistent quality of services to customers.
