The manhole cover is mainly used in urban trunk roads, freight stations, logistics parks, gas stations and other places. Its bearing capacity can reach the D400 level of GB / t23858-2009, and can pass 80 tons. Its characteristics are: strong toughness, high load-bearing, corrosion resistance, high temperature resistance, insulation and flame retardant, impact resistance, wear resistance and other characteristics. The prominent feature is that the material has no recycling value and has the characteristics of natural anti-theft, which can effectively guarantee the traffic safety of the road.
