"Green Top" is a paving material made from natural materials. By using green rock screenings and creating a cross-section with a porous structure, it has excellent drainage properties, and the surface is always in a state covered with top sand. Therefore, it can be said to be a semi-weatherproof paving material with good sliding properties and high safety. 【Features】 ■ Lower initial construction costs compared to all-weather paving (hard coat) ■ Daily maintenance can be done with watering and brushing ■ Good permeability, allowing use after rain ■ Usable for various purposes ■ Safe and environmentally friendly due to natural materials *For more details, please refer to the PDF materials or feel free to contact us.

"Ball Flight Simulation" is more reassuring than just settling for a rough "setting." It is possible to understand the intersection of appropriate safety considerations and cost-effective construction expenses. This is significant in terms of cost-effectiveness, as there are many cases where construction costs have been reduced beyond the cost of this investigation. I sincerely hope that one day this type of research will be legislated as an efficient means of ensuring safety management in sports scenes. 【Phase 1: Verification for Design Contractors】 ■ Simulate the ball flight profile from a horizontal angle of 0° towards the center, in increments of 15°. ■ The profile will be conducted at vertical angles in increments of 10° from 10° to 170°. ■ Due to the uncertainty in measuring wind influence, input is not required. ■ Only the simulation "data" will be provided as CAD data (please consult us regarding compatible CAD). *For more details, please refer to the PDF document or feel free to contact us.
