Composite Manhole Cover - Round 700MM

It adopts macromolecule complex material and reinforcing steel bar moulded by high temperature and press at one time. Its highest inspect result is 54 tons, accord with Construction Department of Peoples Republic of China CJ/T211-2005 Criterion.

2. Beautiful Show:

Manhole cover’s external pattern has fine design; it can be made in many colors to beautify the environment.

3. Light Weight:

This kind of material has no recycle worth so it was burglarproof.

4. Burglarproof:

This kind of material has no recycle worth so it was burglarproof.

At the same time it has locked construction design, it can make the goods in the well avoid stolen. Avoid City Black Hole accident.

5. Climatic resistant:

It uses big molecular weight and chemical steady macromolecule complex material, adopts scientist prescription, advanced and perfect technique equipment. The product may be used in -50--+1.

6. High Precision :

Due to its high temperature mould press at one time there is a smaller aperture between cover and its under. It gets over the problem such as run, jump and sound of cast-iron and cement manhole cover. It improves traffic ability and travel comfort.

7. Anti-Corrupt :

Inspected by National Chemical Construct Material Inspection Center, it has obvious advantages of anti-acid, anti- alkali, anti-corrupt and anti-aging. Many indexes reached third class, longer service life .
