My factory is located in Yantai, a costal city in the north of China. We have been manufacturing boat trailers, jetski trailers, ATV trailers and semi car trailers since 2005. The trailers are made of galvanized steel with LED water-proof lights. So they are welcomed by being professional and very good quality. Their sizes are 3.5m to 9.5m by total length. Trailers can be tailor-made if you would offer the boat's length, width, weight with engine. We are always at your service.
