VMKON maple hardwood flooring delivers 57% shock absorption (Grade-1 requirement: 50–75%), balancing cushioning and stability for high-impact activities. This helps reduce impact stress during jumps and fast transitions, improving athlete comfort and safety while keeping the court responsive(basketball, badminton, etc).
The system is designed for demanding daily use. It shows strong resistance to wear and deformation, with 33 mg wear loss (requirement: ≤ 80 mg) and 0.30 mm indentation under rolling load testing(requirement: ≤ 0.50 mm), no visible damage observed, supporting reliable performance under foot traffic and equipment movement.
Playability meets competition needs with 94% ball rebound(requirement: ≥ 93%), providing consistent and predictable response. The floor also achieves a slip resistance value of 95 (requirement: 80–110), supporting controlled movement for quick starts, stops, and direction changes.
Enhancing both performance and aesthetics, the surface features a refined low-gloss finish with 27% gloss at 85° (recommended: ≤45%). The reduced gloss helps minimize glare and improve visual comfort under typical indoor lighting, while maintaining a clean, modern court appearance.
