WELL COVER  INTRODUCTION
Composites are materials with new properties composed of two or more materials with different properties by physical or chemical methods. Different materials learn from each other and produce synergistic effects, so that the comprehensive properties of the composite materials are better than the raw materials and meet different requirements!
The fiber reinforced resin matrix composite well cover produced by our company is made with unsaturated polyester resin as the matrix material, steel fiber (reinforcement framework) as the reinforcing material, supplemented by certain filler and curing agent, and hot pressed by hot pressing die machine for thermal insulation and demoulding.
Fiber reinforced resin matrix composite manhole cover has the advantages of high polymerization degree, high density, good impact and tensile strength, wear resistance, corrosion resistance, no rust, no pollution and maintenance free
