EPDM floors boast several remarkable advantages. The surface layer showcases a pattern of green bean - shaped swirls with different heights. This design not only boosts the aesthetic charm and alleviates visual fatigue but also guarantees that the anti - slip value fully adheres to the physical performance criteria of the new national standard GB36246 - 2018. The bottom layer takes inspiration from the waffle shape and is equipped with drainage grooves. This innovative design effectively resolves the issues of water accumulation and drainage at the bottom, while ensuring that the impact absorption and vertical deformation meet the physical performance requirements of the new national standard GB36246 - 2018. The connective edge makes use of mortise and tenon joints and nail hole techniques, making the edge assembly more stable and tackling common problems like edge curling and cracking, which are prevalent in existing sports surface layers on the market. The center design includes four evenly spaced air vents, successfully solving the problem of surface layer blistering, which is often caused by the aging of the foundation or adhesive in traditional prefabricated sports surface layers.
