The Product Structure
The excellent performance of SPU
The purpose of building sports courts is to ensure a professional,safe,healthy sports condition-the characteristics of hardness will bring the professional sporting feeling;the cushion effectively increasing the shock absorption and reduce the incidence of injuries to ankles,joints and ligaments.At the same time,it should reduce abrasiob caused by falling and accident.
