Shanghai Cheng Sheng Sports Facilities Co., Ltd. has specialized in the production of polyurethane surfacing materials chemical production plant, has a perfect professional equipment, advanced production technology and complete testing means, while the Institute for Advanced Flexible Cobourg an expert attainments Technology team. I produced licensing Sheng Cheng polyurethane plastic runway, the plastic floor, safety elastic pad is a national hi-tech industry, and the national patent, product quality fully meet international advanced level, major products have international authority - Britain CST detection qualified meet BS7188 standards; receiving sentinel testing country's most authoritative sports product testing organizations East China University of polyurethane Quality Inspection Center, in line with GBT14833-93 standards. In 2000 the Ministry of Construction continues to provide unique new green building materials BrandName. Companies in good faith, pragmatic spirit, welcome all the friends of insight to our company to negotiate business, seek cooperation and common development. 1. Standard runway length of 400 m, by two parallel straights and two equal to the radius of the curve components. Weeding to the runway, along the inner side of the runway sudden application of a suitable material to be boundaries. Ledge about 5 cm wide and at least 5 cm. 2. Should projecting beyond the outer edge of 30 cm measured along the length of the runway at the runway. If no curbs should be measured at 20 cm beyond the outer edge of the marker line. Note: "IAAF Track and Field Facilities Manual" contains all the relevant track structure, design, technical information flag. This rule gives the basic principles that should be followed. 3.400 m and 400 m of the following track, each athlete should occupy a lane, lane width of a minimum of 1.22 meters and a maximum of 1.25 m, lane width of 5 cm, all lanes should be the same width. The provisions of paragraph 2 shall measure the length of said first lane and the other lane length shall be measured at 20 cm beyond the outer edge of the inside lane line. NOTE: lane width should include the right of the lane lines characteristic color: special polyurethane particles, surface color and soft, granular surface, preventing reflection bright glare of the sun, beautiful durable, and multi-color matching. Economy: maintenance facilities, saving management costs. Security: You can prevent sports injuries fall occurred. Adhesive: special construction process, strong bonding, can inhibit the water rises, no bubbles, peeling and so on. Flatness: Use self-leveling construction material, flat surface, can meet the particular requirements of a flat playing field. Impact resistance: a tough elastic layer and buffer layer, can absorb strong impact, the surface will not be damaged. Anti-nail forces: the maximum force most frequently used starting point by the meter, will not be spikes or starting frame damage. Reduction of wear: the weight is not due to the track and field equipment can not restore elasticity. Wear: wear resistance of less than 2.5%, to meet schools at all levels for a long time, the use of high frequency requirements. Shock absorption: a moderate pace to absorb impact, reduce injuries, long-term training and competition are affordable.
