The sandwich system running track is a high-performance structure composed laid with environmental friendly SBR granules as the bottom and buffer layer, PU strengthening layer and the surface sprinkled with EPDM granules. The surface adopts color fine EPDM granules, providing high color fastness, non-slip and UV resistance. The base offers excellent elasticity and cushioning, resistant to spikes, with a balanced firmness and high durability. The surface sprinkled with EPDM granules effectively protects athletes from injuries. The sandwich system running track combines the advantages of mixed surfaces and air permeable bases, providing long-lasting durability, excellent elasticity, moderate comprehensive performance, dynamic design features and fast construction. Also, different process and differnt colors of the surface is avaliable to create the best quality and cost-effective solution tailored for you.
Mainly applicable to tracks and fields in schools of various levels and professional stadiums, including semi-circular areas and auxiliary zones. Also suitable for community sports facilities, indoor gymnasiums, playgrounds, and regular sports competitions,etc.
