Composite Schachtabdeckung / hohe Reichweite Kanaldeckel

The products are the high-strength manhole cover and water grates researched and developed by the company in 2002.The products are produced through forming a high-density whole by high-temperature moulding with high-strength W-SMC sheet moulding plastics, being the base material.The products are shaped like iron plates with a hard texture,and have made up for the defect of BMC reinforced products for inconformity with testing load. The load of the products have met the requirements of GB/T23858-2009 standard through verification by the state authentic departments with its maximum load reaching 900KN.At present,the products have been widely used in inspection wells of power,telecommunication,mobile communication,fuel gas pipes and chemical bases etc., and real estates,urban arteries,high-grade highways,expressways,freight transport piers and airports etc.. 1.Excellent electrical insulation resistance ,arc resistance and signs of leakage. 2.Excellent mechanical strength ,flame resistance and heat resistance. 3.Non-recycle value for anti-theft. 4.Anti acid ,alkali and chemeical corrosion,impact resistance ,anti-rust,water-ability,durable (30 50 years),locking option.When damaged,no holistic hole,avoids sudden accident.Use the superfine calbonate ,good density. 5.Only 1/3 weight of the cast iron one ,and 1/2 of the BMC with steel one. 6.Convenient transportation and installation reduce work intensity. 7.Physical appearance is beautiful,smooth,no distort ,easy to open.Unique multi-directional stop resisttant tread pattern. 8.Noise is very low and rebounding free when car roll on. 9.With perfect decoration effect and the color will be the right Applications: (1) Electric power pipeling well;post,telecommunication,communication pipeline well; (2) Street lamp well,fire control well,all kinds of valve well; (3)City water,drainage pipeline well;heat supplied,gas well; (4)As cover board for anti-corrosion project
