Why are there still many people who don’t know the SMC Manhole Cover?
The Composite Manhole Cover is a kind of new manhole cover, and its designability is also very strong. A few days ago, a customer found us that Bast said that it was required to customize a sewage pipe manhole cover. The manhole cover must be able to be locked, have good sealing performance, and be corrosion-resistant so that workers can carry out post-maintenance work.
There are three types of manhole covers that we use:
1. The cement manhole cover is cheap, but the sealing is too bad, so it is excluded.
2. the cast iron manhole cover is high in price, the weight is not easy to be washed away in the water but it is easy to corrode, the maintenance work is difficult in the later stage, and the sealing is poor, so it is excluded.
3. composite material BMC manhole cover, the price is low, but due to the special nature of the material can not install the locking device, so exclude. The composite SMC manhole cover has the right price, good bearing capacity, corrosion resistance, good sealing performance, and lightweight. It only needs to install the locking device to solve the above problems.
The customers went to Zhejiang, Anhui, and Guangdong to find several, and did not find a suitable SMC manhole cover manufacturer, because their main business is to produce BMC manhole cover and sand manhole cover. Their sideline is to produce SMC manhole cover, which makes the customer's sense of trust is reduced, and finally, we are found.
This reflects a problem. Although the market has a large production volume and sales volume, the 85% is BMC sand cover, 10% is BMC without sand cover, and the last 100 The fifth is the SMC manhole cover (that is, the manhole cover that the customer needs). Then the problem is coming again, why the market for SMC manhole covers is so small, and there are so few people who know. Since the composite manhole cover has just entered the manhole cover market since the beginning, the advantage of the low price of BMC sand cover is rapidly expanding, which leads many users to think that the composite manhole cover is BMC sand cover, they have not even heard of SMC manhole cover. This is really a cruel fact.
SMC manhole cover is composed of SMC composite material, ie, the main raw material of sheet molding compound, which consists of special yarn, unsaturated resin, low shrinkage additive, filler, and various additives. It is a dry molding plastic mold for unsaturated polyester fiberglass products. It is characterized by toughness, wear and corrosion resistance, natural anti-theft, high load without reinforcing steel reinforcement, and a well cover of FN900 load grade for airport runway is a good example.
According to the fourth item of GB/T23858-2009 "Inspection Manhole Cover", the manhole cover is divided into six grades according to the bearing capacity:
A15: green belts, sidewalks and other areas where motor vehicles are prohibited from entering.
B125: sidewalks, non-motor vehicles, car parking lots and underground parking lots.
C250: residential area, back alleys, only light motor vehicles or small cars driving, within 0.5m of curbs on both sides of the road.
D400: urban trunk roads, highways, highways, and other areas.
E600: freight station, dock, airport, and other areas.
F900: Airport runway and other areas.
Zibo Best Energy-Saving Materials Co., Ltd. is a professional manufacturer of SMC manhole covers. It has been established for 15 years. Since its establishment in 2004, it has strictly implemented production standards in accordance with national standards, both in terms of bearing capacity and manhole quality. Reach the maturity stage. It is a rare high-quality manhole cover in the current manhole cover market. It is a special manhole cover for high-load areas such as urban main roads, highways, gas stations and docks. It is also popular among users in Europe, America, Australia, and Asia.
