Natural Lawn or Artificial Lawn?
As we all know, there is a big difference between a natural lawn and an artificial lawn, so should we choose a natural lawn or an artificial lawn?
Characteristics of artificial grass and natural grass
Shock absorption performance: 50% - 70% for natural turf and 5% - 70% for artificial turf.
Deformation performance: for natural turf, the muddy turf soaked in water has great deformation, while the dry turf has little or no deformation; The deformation degree of artificial turf is between 1 and 7 mm.
Anti-skid performance: natural turf is required to be 0.6-1.0, and artificial turf is required to be 0.6-1.0
Resistance: the resistance value of natural turf is 25-50 nm; The resistance value of artificial turf is 35-45 nm.
Sliding distance: the sliding distance of natural turf is 0.20-0.55m; The sliding distance of artificial turf is 0.25-0.45m.
Effects of artificial turf and natural turf on ball
Vertical bounce height: the value of natural turf is between 25% and 45%; The value of artificial turf is between 30 ‰ and 42%.
Rolling speed of the ball: the value of natural turf is 4m-10m; The value of artificial lawn is 4m-10m.
Bouncing of balls from different angles: landing at an angle of 25 degrees, bouncing speed of 50 kilometers per hour, and height of 60% to 80%.
Field test of artificial grass and natural grass
Slope: the slope of an artificial lawn shall be less than 10%; The slope of a natural lawn shall be less than 0.5%.
Flatness: the flatness of an artificial lawn is less than 10mm within 3M and less than 2mm within 300mm; The acceptable value of natural lawn flatness shall not be greater than 30mm, and the optimal value shall not be greater than 20mm.
Water permeability: the permeability of an artificial lawn foundation is greater than 180 mm / h; The permeability of natural turf foundation is greater than 180 mm / h.
Searching for an Artificial Lawns supplier, wholesaler, manufacturer from China, you can get high-quality products at a nice price.
