Beijing fake lawn wholesale phone; 13520710367 Zhang artificial turf appearance of bright green seasons, lively, good drainage performance, long life, low maintenance costs. Artificial turf sports systems on the basis of the quality requirements are mainly concentrated in three areas: hardness, roughness and drainage slope. The basis of commonly used artificial turf three categories: asphalt base, cement foundation, gravel base, which type is determined by the local climate and environment and budget, time, asphalt base is particularly suitable for the climate and environment with a large temperature difference between the north and low winter temperatures, but also because of its high cost, for the warm and humid environment is not the most suitable type of foundation, gravel base because of its simple construction, low cost, rapid drainage, and is more common in the South, but because of its rigidity and stability poor, used for a long period of time prone to loose basis, resulting in uneven basis; Therefore, in most regions of the domestic cement concrete foundation has become economical and practical, very high cost of basic types of artificial grass. Double and Sports based on a wealth of experience in the artificial grass system, cement concrete foundation of artificial grass brief introduction as follows: 1, on the basis of surface roughness to ensure that the artificial turf surface layer of uniform thickness, uniform elastic. Flatness pass rate above 95%, 5 m ruler error 3MM, slope: horizontal 8 ‰, vertical 5 ‰, semi-circular area 5 ‰, the surface should be flat, smooth, to ensure drainage. 2, the base should have a certain strength and stability. 3, the surface uniformly solid, no cracks, no bad side pockmarked face, straight and smooth seams, direct wholesale production of plastic fake lawn turf manufacturers turf prices soil lawn production, plastic lawn Stadium turf; simulation turf, artificial plastic lawn wholesale, retail, direct manufacturer specifications, 25 x 25 cm, aged x 60 cm, 30-150 yuan per square meter price, large factory direct ordering
