Senria Sports Prefabricated Track Rubber Roll Outdoor Flooring Sport Flooring Building Material
The prefabricated rubber track roll is divided into two layers: the upper layer is a wear-resistant layer with 3-5mm deep concave convex grain, which provides the friction and elasticity required by the track; the lower layer is a square frame structure with 6-10mm deep inclined angle, which provides the impact absorption and main elasticity required by the track.The feature of this structure is that it can gather the scattered reflection force relatively, and act on the athletes from the angle that accords with the forward direction of the athletes to improve their performance.
Application
The international/national athletic track,track and field of primary and high schools,gym footpath,etc
The Excellent Sport Performance
1.Strong friction and grip,even perform well in wet climate
2.Excellent shock absorption and resilience
3.Factory prefabricated and product quality is completely controllable
4.The best tear-resistance,can withstand a higher load existed in various applications
5.IAAF certificated products for national and international competition
