{dede:global.cfg_gsname/} | Updated: 2020-06-18 00:43:00
The composite manhole cover has the following characteristics in technology:
The composite manhole cover is made of high polymer composite material, with steel bar as th main internal framework, and is produced by high temperature molding. Its strength can load bearing capacity 50tons.
The manhole cover is light in weight, convenient for transportation and installation, and can greatly reduce labor intensity. The new resin manhole cover has a good anti-theft performance. Because the synthetic resin material has no recycling value, effectively put an end to the emergence of "Urban black hole"
The composite manhole cover has high precision and corrosion resistance. After high temperature molding production, it has good acid and alkali resistance and corrosion resistanc, effectively extending the service life of resin manhole cover.
