Due to the special requirements of the project, we required the height of the light poles to be unified to 8.5 meters, and we needed to customize the embedded parts according to the local standards. During the communication, the manufacturer took the initiative to provide the design drawings for confirmation, and also filmed the semi-finished product videos and provided real-time feedback during the production process. After the arrival of the goods, we found that the embedded parts were exactly the same in size, and even the packaging was reinforced according to our port loading and unloading habits, which saved a lot of trouble in customs clearance and handling. The professionalism deserves praise
