The sandwich track adopts a high-performance surface structure composed of multiple layers, and the surface is granular, with strong waterproofness, high elasticity and dynamic design. The bottom layer is made of polyurethane adhesive in a controlled proportion of the special rubber particles. The thickness is laid by a professional construction machine, the flatness is excellent, and special rubber particles are spread on the surface. It is suitable for large stadiums and schools.
All-weather: Maintain high quality in any season and temperature difference, and use it after rain to improve utilization.
Good flatness: professional construction machinery construction to ensure double marking of runway thickness and flatness.
Appropriate elasticity: The porous bottom layer, with moderate elasticity and rebound, can reduce physical exertion and increase competition performance.
Impact resistance: It has a strong buffer layer, which can absorb strong impact force and reduce sports injuries. It is suitable for long-term practice and competition.
Strong nail resistance: Even when the force is the most, the most frequently used 100-meter starting point, the surface will not be damaged by spikes or starting blocks.
Strong weather resistance: special rubber surface, can resist ultraviolet, ozone, wind and rain, sulfuric acid, gas pollution, and extend the service life.
The appearance is gorgeous: the color is beautiful and beautiful, the surface layer can not be granulated, the maintenance is simple, the management cost is saved, and the cost performance is high.
Applicable to official track and field competitions, general sports competitions, various types of school venues.
