Congratulation:Team China player lifted the FIVB Women's Volleyball World Cup trophy with perfect 11 straight wins.Spikes,shots,jumping to kill blocks...Team China players all plays excellent and successfully defend champions. When the ball hits the floor, I can't help but wonder about the structure and scale of the volleyball court.Let's talk about the volleyball court design specifications here. The volleyball competition is rectangular in shape and has a length of 18 meters and a width of 9 meters. There are at least 3 meters wide barrier-free areas around. The floor of the FIVB World Competition venue can only be wood or plastic or other synthetic materials. The floor of volleyball court must be flat,not rough, slippery, and there should be no hidden dangers that could harm the athletes. We thought that the best flooring material for volleyball venues would be the acrylic stadium or the silicon pu court. This kind of floor has advantages of flatness, seamless and uniform,what's more,the floor  surface is slip-proof to prevent falls,ensuring the safety of the exercise process.Ethletess can run and jump freely and confidently.In addition,this kind of floor also has the characteristics of wear resistance and water resistance. The volleyball net is 9.50 meters long,1 meter wide, and the mesh is 10 cm, black. The center line is under the net and is the line connecting the midpoints of the two side lines. The court field is divided into two equal fields. The volleyball net heights are different for men’s, women’s. The net column should be smooth, preferably with height adjustment. The placement of lighting equipment should not impede the athlete's vision. Volleyball requires skill and skill. It also requires a good venue. All venue equipment has a goal to eliminate all dangerous facilities or obstacles and ensure a good environment for the athletes. Ground materials need to be healthy, environmentally friendly and non-toxic. It is also necessary to have a professional construction team. Otherwise, can you use them with confidence?
