Why SMC Manhole Cover Quality Than BMC Manhole Cover
BMC (Bulk Molding Compound / group-like plastic)make the unsaturated resin as matrix material, with 30-50mm short fiber materials as the reinforcing material, with CaCO3 as filler, as prefabricated molding. BMC molding covers--- mold plastic with reinforced ,then under a certain temperature and pressure to be formed ) that covers are made of reinforcing material ,which is a short 30-50mm staple fiber composite material formed of continuous fiber strength of only 20-30%), the structure of the Composite Manhole Cover with the ribs as flat bottom .All the materials are composite and environmental.
SMC manhole cover are the abbreviation of sheet molding compound manhole covers, which are namely sheet molding compound plastic. It's made by the SMC special yarns, unsaturated resin, low shrinkage additives, fillers and various additives composition. SMC has excellent electrical properties, corrosion resistance, light weight, and engineering design easy, flexible, etc. Its mechanical properties can be comparable with some metallic materials, which are widely used transport vehicles, construction, electronics/ electrical and other industries.
Manhole covers are removable plates which form the lid over the opening of a manhole. They prevent anyone or anything from falling into any manholes or sewage openings, and keep unauthorized persons out. OSDEON manhole covers have varying load tolerance, depending on the application.
A15 (Max Load=1.5 Tonnes): Areas which can only be used by pedestrians and pedal cycles.
B125 (Max Load=12.5 Tonnes): Pedestrian, pedestrian areas and comparable areas, car parks or car parking decks.
C250 (Max Load=25 Tonnes): For gully tops installed in the area of kerbside channels of roads which when measured from the kerb edge, extend to a maximum of 0.5m into the carriageway and a maximum of 0.2m into the pedestrian.
D400 (Max Load=40 Tonnes): Carriageways of roads (including pedestrian streets), hard shoulders and parking areas for all types of roads or vehicles.
