Use sheet molding compound materials, today let us introduce the characteristics of manhole cover:
Fire-retardant, anti-static and anti-leakage functions.
No recovery value and anti-theft: the plastic manhole cover use the no recycle value material and will solve the stolen problem thoroughly.
High load capacity: plastic manhole covers have a high load capacity exceeds the ductile iron strictly conforms to BS EN124 Standard.
Light weighted: manhole covers of composite material is 30% lighter than covers of iron, which allows easy transportation and maintenance.
Free-design: It can be designed according to users' demands, including size, color, pattern, specification.
Well sealed: It can be used effectively prevent those poisonous gases leaking out from cesspool.
Sheet molding compound manhole covers use unsaturated resin as the base material and long glass fiber reinforced composite manhole cover. Because the structure adopts the bottom structure of the pot, the data is evenly stressed, and continuous fiber reinforcement is applied, and no reinforcement is required. The materials are all sheet molding compound.
