BMC manhole cover

The different between BMC Manhole Cover

BMC: make the unsaturated resin as matrix material, with 30-50mm short fiber materials as the reinforcing material, with CaCO3 as filler, as prefabricated molding.

Because its short fiber materials many factory can add different things into manhole cover.

Load bearing capacity we can choose BMC manhole cover but many people choose with sand BMC products. Do you know raw material add sand can destroy manhole cover's load bearing(sand affects the internal space of the manhole cover raw materials) and improve the weight of manhole cover)
