Ductile Iron Round Manhole Cover/Composite Manhole Cover for Septic Tank

Ductile Iron Round Manhole Cover/Composite Manhole Cover for Septic Tank


1. Against theft ---WEIFANGSHENGAO 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.
 
2. Application:
 
(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) Anti-corrosion project, open ditch; It as well as can be made according to customers requirements.
