Product Description

SMC BMC Fiberglass Resin Composite FRP Manhole Cover

A. FRP Manhole Cover introduction

FRP Manhole Cover also called GRP manhole cover,mainly divided into SMC( Sheet Molding Compound) and BMC( bulk molding compounds) covers accoding to material difference.They are both fiber reinforced plastic manhole covers. FRP(Fiber reinforced plastic) is newly developed material of manhole covers.Before FRP came into existance,manhole cover were traditionally manufactured from concrete,steel fibre concrete,cast iron,ductile iron or PVC material,but these materials had their
own shortcomings like low load carrying effciency.FRP is considered to be the best alternate material for manhole covers as it has longger lifespan and has the capacity to withstand heavy loads.Increase in heavy traffic and expensive metals completely replaced traditional covers with FRP manhole covers.

B. FRP Composite Manhole Cover Advantages

1. Non recyclable which makes it of no value, hence eliminate incentive for stealing.
2. Resists weight for up to 40 tons.
3. Lightweight.
4. Bottom lid designed to maintain perfect fit and avoid displacement.
5. Non-Abrasive.
6. Resists bacteria and will not rot.

The appropriate class of manhole covers or gully gratings to be used depends on the place of installation.The various places of installtion have been dvided into groups numbered 1 to 6, as listed below.Figure 9a and figure 9b show the location of some of these groups in a highway envionment.

Group 1(min.class A15)
Areas which can only be used by pedestrians and pedal cyclists.
Group 2(min.Class B 125)
Footways,pedestrian areas and comparable areas,car parks,or car parking decks.
Group 3(min.Class C 250)
For gully tops installed in the area of kerbside channels of roads(Figure 9a) which when measured from kerb edge,extend a maximum of 0.5m into the carriageway and a maximum of 0.2m into the footway.
Group 4(min Class D400)
Carriageways of roads(including pedestrian streets),hard shoulders(Figure 9b) and parking areas, for all types of road vehicles.
Group 5(min. class E600)
Areas imposing high wheel loads,e.g. docks,aircraft pavements.
Group 6(min. class F900)
Areas imposing particularly high wheel loads,e.g. aircraft pavements.

Product application

plastic en124 composite smc standard handle smc manhole cover price

FRP manhole cover is widely used in water and allow water collecting pavement after its remit urban drainage system, applicable to all kinds of pavement installed use, including road both sides of highways, the park, the square of rainwater drainage system. Can be designed according to user requirement artesian level and surface scheme.

Product Features

plastic en124 composite smc standard handle smc manhole cover features:
1. Against theft ---SMC manhole cover is non-metallic, non-conductive and non-sparking. It has no value of recycling, thus
completely solving the problems caused by theft.
2. High load capacity ---Its main components are fibreglass and unsaturated resin. JINMENG's existing moulds load capacity are
A15, B125, C250, D400, E600.
3. Free design---Sucs as Color, Logo, Panel, Load and Dimension can be desigened according to the requirements of customer.
4. Long life ---Minimum lifespan of 30 maintenance free years.
5. Well sealed ---It can be used hermetically, and effectively prevent those poisonous gases leaking out from cesspool. Well sealled, no noise pollution or rebound.
6. Good wear and corrosion resistance ---It will never rust because it has good wear and corrosion resistance.
7. High and low temperature resistance ---Excellent insulator against heat ( from-40°C~200°C)
8. Lighter weight and more competitive price--- the weight of composite manhole cover especially SMC manhole cover is lighter. The composite manhole cover is more convenient to transport, install and repair.
