Mold foaming, rotary cutting, uniform thickness. Rotary cutting seamless technology standardized fully automatic process production, precise control of product thickness (thickness error is only ±0.1mm).
Semi Prefabricated Running Track developed by LIKE SPORTS represents the next generation of athletic surface technology — a hybrid system that perfectly balances the precision of prefabrication with the flexibility of on-site installation. This semi-prefabricated roll material for running track is produced in controlled factory conditions, ensuring consistent density and elasticity, then seamlessly bonded and finished on site to create a continuous, joint-free surface.
◎Mold foaming, rotary cutting, uniform thickness. Rotary cutting seamless technology standardized fully automatic process production, precise control of product thickness (thickness error is only ±0.1mm).
◎Factory prefabrication ensures flatness and seamless integration! The material does not deform, warp, arch, or crack.
◎High-density polymer products have excellent elasticity and shock-absorbing functions. It is resistant to compression deformation, bending and friction.
◎Good durability, no displacement cracking due to thermal expansion and contraction; high and low temperature resistance, the material can adapt to ambient temperatures of -40℃ to 80℃ after curing.
◎Excellent mechanical properties, elongation at break reaches 2 times the standard of GB36246-2018, and tensile strength reaches 1.5 times the standard of the new national standard.
◎100% of on-site sampling passes the new national standard.
◎Factory prefabricated products do not require any auxiliary materials to be added during construction, greatly shortening the construction period. Reducing construction periods by up to 40%.
◎The semi-prefabricated running track features an independent surface layer that can be re-sprayed or refinished without replacing the entire system, extending the track’s lifespan and reducing maintenance costs.
◎The semi-prefabricated roll material installs easily on multiple base types, including asphalt, concrete, and refurbished existing tracks, ensuring wide adaptability for both new construction and renovation projects.
◎Manufactured using advanced polyurethane technology, the running track is free from plasticizers, heavy metals, and toxic additives. Its low VOC formulation ensures safety for athletes and environmental compliance with modern green building standards.
