Quality Supplier Manufactured SMC Manhole Cover

Normal size of SMC manhole cover: Φ 300, Φ 400, Φ 500, Φ 500, Φ 600, Φ 600, Φ 700, Φ 700, Φ 700 D400, Φ 800, Φ 1000

SMC well cover is also known as sheet molded plastic well cover. It is a high-strength composite product which is made of unsaturated polyester resin, thickener, initiator, cross-linking agent, low shrinkage additive, filler, internal release agent, colorant and other mixture impregnated with chopped glass fiber roving and shaped by special process through high temperature and high pressure hydraulic pressing.

1. High strength, light weight and convenient maintenance. The density of this product is only 1 / 4 of that of steel, but its strength can exceed that of steel after special processing.
Widely used in urban and rural roads, airports, gas stations, telecommunications, communications, water, gas and other important transportation roads.

2. Security. There is no metal interlayer in the material, so it can be used safely in remote places without monitoring facilities.

3. Prevent noise pollution. Compared with the metal well cover, the vehicle will produce a lot of noise when passing by, especially when the cover seat is loose, it will cause a harsh noise. The SMC material can reduce the noise caused by vehicle passing.

4. Super corrosion resistance, wear resistance, anti-static. The service life can be more than 50 years. It can be used normally from - 40 ℃ to 100 ℃, and its service life is more than 5-10 years longer than that of nodular cast iron well cover, and more than 30 years longer than that of steel fiber well cover and BMC well cover.

5. Non hollow structure makes it suitable for all kinds of complex traffic sections and construction sections. For rural domestic sewage road excavation, leveling, renovation and other construction technology is complex, the road conditions are complex, need excavators, rollers frequent access, it is difficult to install the sewer cover according to the standard process. For the common well cover, it is very easy to damage the well cover and break the hole, which will bring great maintenance cost to the subsequent project operation and maintenance. However, SMC well cover can not be destroyed in various complex situations because of its strong pressure resistance and wear resistance.
