manhole cover and frame

详情

The products are the high-strength W-SMC manhole cover and water grates researched and developed by the company in ***9.The products are produced through forming a high-density whole by high-temperature moulding with high-strength W-SMC sheet moulding plastics(under the patent application number of ***********2.5) being the base material.The products are shaped like iron plates with a hard texture,and have made up for the defect of BMC reinforced products for inconformity with testing load.

1.     High Intensity:

     It adopts macromolecule complex material and reinforcing steel bar by high temperature mould press at one time. Its highest inspect result is *4 tons, accord with Construction Department of Peoples Republic of China CJ/T*******5 Criterion.

2.     Beautiful Show

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

3.     Light Weight

It weight only 1/3 of cast-iron manhole cover, more expediently transport, install, and rush to repair, lighten the work intensity.

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. Stop 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 ****-***0.

6.     High Precision

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

7.     Anti-Corrupt

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

It has been plentifully used in city planning project, and gained good reputation.

8.     Jinmeng burglarproof manhole cover was famous band of manhole cover industry, we will continuously take innovation and non stolen, non rot, low price, good quality as promises to create a new future.
