Product Description

Composite Manhole Covers/Watertight Manhole Covers for Garden Drainage



1. Against theft ---WEIFANGSHENGAO Composite Manhole Cover with shockproof rubber sealing is non-metallic, non-conductive and non-sparking, has no value of recycling, completely solving the theft problems.
2. High load capacity ---Its main components are fibreglass and unsaturated resin. JINMENG's existing moulds load capacity are A15, B125, C250, D400, E600. 
3. Free design---Such as Color, Logo, Panel, Load and Dimension can be desigened according to the requirements of customer. 
4. Long life ---Minimum lifespan is 30 years free of maintenance .
5. Well sealed ---It can be installed hermetically, and effectively prevent poisonous gases leaking out from cesspool. and no noise pollution or rebound.
6. Good wear and corrosion resistance ---It will never rust because it has good wear and corrosion resistance.
7. High and low temperature resistance ---Excellent insulator ( from-40°C~200°C)
8. Lighter weight and more competitive price--- the weight of composite manhole cover especially SMC manhole cover is lighter. The composite manhole cover is more convenient to transport, install and repair.

Feature	Technical
high strength	the use of polymer composite materials, with steel frame, high temperature molding, the highest test results up to 54 tons, in line with the latest CJ and over People's Republic of China promulgated by the Ministry of Construction / T211-2005 standards.
beautiful appearance	manhole covers surface pattern designed, can be made into a variety of colors, beautify the urban environment.
light weight	only about one-third the weight of cast iron, easy to transport, installation, repair, greatly reducing the labor intensity.
anti-theft:	the synthetic material recovery value, natural anti-theft; and a locking structure, to achieve the well property theft. Can completely prevent the occurrence of "urban black hole" of the accident.
weather resistance	This product is made of high molecular weight, chemical stability, high molecular weight material as raw material, through scientific formula, advanced technology, improve technology and equipment so that the product can at -50 °C - + 150 °C normal use .
high precision:	As the product is high temperature molding, seat cover smaller gap seam overcome iron, cement covers "running, jumping, ring" and other issues, improve road capacity and driving comfort.
corrosion-resistant:	Products by the National Chemical Building Materials Test Center, with a significant acid, corrosion resistance, aging index reached three or more, and longer service life.
