Also from the production technology of concrete, the concrete C50 and higher levels of the need for strict quality management system and a high level of construction in the construction. Taking into account the current situation and the quality management system of the current level of construction to C50 divided as an index of high-strength concrete, the intensity level reaches or exceeds the C50 concrete for high strength concrete. High performance concrete concept put forward so far, only 10 years time, building fence manufacturers, it is accompanied by high strength concrete and came out. Safety net into flat net (P), Legislative Network (L), dense mesh safety net (ML). Safety nets mainly by the side ropes, tethers, bars ropes, nets rope components. Dense mesh safety net consists of net body, buckle, side rope and additional tether. Mechanical properties of a safety net physics, is the main indicator determining the quality of the merits of a safety net. Its contents include: side ropes, tether, rope nets, rope breaking strength bars. Dense mesh safety net are: breaking strength, elongation, tensile strength seams, tear strength, penetration resistance, breaking strength retention after aging, opening the eyes buckle strength tail flame retardant properties. Flat screen and Legislative Network should have impact resistance. Legislative Network can not replace net, should distinguish with flat screen height or vertical network according to the construction needs and loads. Flat screen network load strength require more than legislation, the use of more material, construction safety net pricing, heavier than Legislative Network. In general, flat screen more than 5.5kg, Legislative Network greater than 2.5kg. Buying building safety net safety net protection, Anquan Ping network, safety net, Ankang building fence, GB safety net, knotless safety nets, large safety net, nylon safety net, polyester safety net with helmets, safety belts along with people called "Sambo" on the construction site. Safety net is to prevent falls from a height of one of the most effective security facilities of the accident The company's main products are; safety net, Fine Mesh Safety Vertical Net, seat belts, safety rope, transport network, construction safety net specifications, breeding general manager of the network, and a variety of high-strength wire ropes and other companies carrying WANG department managers executives wholeheartedly welcome new and old customers to use our "Yellow Dragon" brand boutique, welcomes foreign businessmen to visit and negotiate business, a joint venture set up factories , cooperation and seek common development and create brilliant. Under normal circumstances 40% of the concrete industry to civil structures carbonized steel surface, and in the more humid environment 90% component has been corroded. Therefore, the durability of the concrete universal attention today, high-performance concrete is undoubtedly address the structural durability of the most effective and most economical way. 1 Scope This standard specifies the safety net definition, product classification, technical requirements, test methods, inspection rules and signs, packaging, transportation, storage and other requirements. This standard applies to construction work at heights with a safety net. 2 References The following standards contain provisions which, through reference in this standard, constitute provisions of the standard, the time of publication, the editions indicated were valid. All standards will be revised, using the standard parties should explore the possibility of using the latest version of the following standards.
