Shock-Absorption Silicon Polyurethane Sport Court Flooring With IAAF Certificate
Product Description
Advantages
1. Hard Top Soft Down
2. 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 abrasion caused by failing and accident
