Waterproof En124 Manhole Cover Plastic Double Seal Manhole Cover

Product Features:
1. Our manhole cover are produced in strict accordance with the EN124 standard, and the products will be pressure tested during the production process and before shipment, and corresponding inspection reports will be issued.
2. The raw materials of our composite manhole cover are strictly controlled. We use the best performance SMC sheet molding compound to produce through high temperature molding production process.
3. Product design can be customized according to customer requirements. Can choose to assemble non-through hole lifting holes, heterosexual manhole cover locks and rubber sealing rings on manhole cover.
4. We have a wealth of experience in exporting goods, and can professionally package manhole cover to ensure the safety of logistics and transportation.
5. The production capacity of our factory is sufficient, and the delivery date of the goods can be guaranteed under normal circumstances.
6. If the product needs to be designed and develop a new project, we can provide customers with design services for free.
7. Our manhole cover supports the testing of third-party SGS/TUV/BV and other institutions, but the cost needs to be borne by the customer.

SMC composite material is the abbreviation of Sheet molding compound. The main raw material consists of GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler) and various additives. It first appeared in Europe in the early 1960s in the twentieth century, in 1965 or so, the United States and Japan have developed this process. China in the late 80's, the introduction of foreign advanced SMC production lines and production processes. SMC composites and its SMC molded products, with excellent electrical insulation properties, mechanical properties, thermal stability, chemical corrosion resistance. So the application range of SMC products is quite common. Now the development trend is that SMC composites replace BMC materials.
