Supply the Nantong Chuangmeng FRP manhole cover, FRP molded covers, composite manhole cover

FRP / composite covers glass fiber products (glass cloth, tape, felt, and yarn) as a reinforcing material, a synthetic resin as a matrix material mainly composed of an unsaturated polyester resin, filler, initiator, thickener, The low shrink additive, the film of mold release agents, pigments and reinforcing materials and other components. Fiberglass covers are to address the steel, iron manhole covers easily corroded and the Pirates lost, too bulky, easy to rattle, and other defects, improve its functional and economic and social benefits and development of the new covers. Edit this paragraph, Features a light weight, the weight of the fiberglass covers only the metal cover 1/4, engineering, installation, and use open and close a lightweight flexible. 2 self-locking, unique constraints link structure, FRP round covers well base has jumped off well base self-locking feature to prevent cars driving by covers. 3 high strength, tensile strength of FRP materials and Q235 considerable compressive strength is more than twice as high than C30X, shock, vibration, fatigue, and fracture properties superior to steel, iron and other material, used as a load-bearing structure of the covers, strength security conditions than iron manhole covers easier to meet. 4 anti-theft loss, glass steel products the waste recycling value, used as covers to to avoid steel covers theft often void of goods sold of hidden prevention covers Pirates of the loss caused by people, vehicles fall into or stuck in traffic accidents in the well, reducing owners economic loss and responsibility for the accident. 5 corrosion resistant glass natural corrosion-resistant steel, used as covers of acid, alkali, salt, sewage and other corrosive media environment, with technology economically competitive Edit this paragraph two, the main purpose is mainly used for municipal roads, water supply, electricity, post and telecommunications, street lighting, residential quarters, garden planning, oil and gas, mining, chemical production, drain cover, sanitation projects. 1, heavy: motor vehicle traffic roads or parking lots. 2, light: prohibit motor vehicles to enter the green space, channels, bike paths or sidewalks.
