Tianjin Rostone Fitness Products Co., Ltd.

The RING trampoline sets are our deluxe products. We have 15ft, 12ft, 9ft and 6ft RING trampoline sets available now. We developed the RING trampoline sets in 2009. They look very nice and professional, and their quality is quite high. We use the best materials for every part of RING trampoline sets. Our RING trampoline sets are just the deluxe trampoline sets on market.

The frame and legs of RING trampoline are made of galvanized steel pipes. Both outside and inside of the steel pipes are galvanized completely. Then, we make powder-coating on outside of frame and legs by special processes. Thus, the outside of frame and legs has 2 layers of protection. The 1st layer is powder-coating, and the 2nd layer is galvanization. The inside of frame and legs has galvanizing protection which is same as other high-quality trampolines. In this way, the trampoline frame and legs are not only more durable but also more beautiful than other trampolines.
The surface of our powder-coating has smooth crinkles. It looks more deluxe than normal powder-coating.
We use the top quality powder for our coating. Although the cost of powder is 2 times higher than normal powder, the coating is thicker, nicer and more durable.
We make the bottom of pad in our innovative design. The joint between sections of pad can be filled up by foam when the pad is set up. The whole pad looks like one solid section. It is more difficult to make, but the pad is nicer a lot.
We put FRP poles on the top of safety net. It makes the top of safety net in nice shape.
The top of support poles for enclosure are bended towards outside of jumping area. The diameter of the top ring of enclosure is bigger than the bottom ring. In this way, it can prevent the user from knocking his head onto the top ring during his jumping. It is a safer design.
