prevent of stealing, high load capacity, long using life, free design, also cab be well sealed if it is needed.

Our manhole cover is made of fiberglass, resin, quartz powder and some additivies. we make our composite manhole cover in two style, one is made of all FRP without steel, the other is made of FRP with steel inside.

Because it  is no recovery value of this material, so it is no use for others, this will revolve the problem of the manhole cover- stolen problem thoroghly. its main components are fibreglass and unsaturated resin, it is strong enough to support the load, it is no problem for its load capacity as strong as ductile. It cab eb designed according to the user's demands, including color, pattern, specification. It will not rust because it has good wear and corrosion resistance.
