Last week, we finished a double-stacked bike rack project in Beijing. The project is located in the basement with an inclined roof which caused the room with insufficient clearance in the low area. We canceled the upper bike racks which left the only lower bike racks in these lower areas. The floor has a deep slope that the lower bicycle racks can be easily slid to one side. Fortunately, our installation team has finally solved this problem. The customer has a high evaluation of our professional service.
