Fuzhou composite manhole covers are reinforced with mesh reinforcements, and the key stressed parts are specially strengthened. When an unavoidable external force impact occurs, the pressure can be quickly dispersed to ensure the safety of people and vehicles. It does not contain metal, and the reinforced skeleton of stone plastic manhole cover and concrete manhole cover is less than 1/10 of the total weight of the manhole cover. Not much stealing value. And because the strength of the manhole cover is extremely high, it is extremely difficult to remove this small steel bar from the manhole cover. This is why composite manhole covers can stand out in today's highly competitive market.

The acid and alkali treatment of the composite manhole cover can adopt the sequence of alkali → acid → alkali, acid and alkali dosage and flow rate, and high temperature and high pressure one-shot molding technology, high polymerization, high density, good impact resistance and tensile strength, and wear resistance , Corrosion resistance, no rust, no pollution, maintenance-free and so on.

In the process of using composite manhole covers, we are concerned about theft prevention. Today, new types of antitheft devices can be used to prevent this phenomenon.

The composite manhole cover of any specification only needs to drill two holes as required, and it can be equipped with anti-theft device. For newly made manhole covers, two holes are reserved as required during casting, and anti-theft devices can be installed. The composite manhole cover equipped with the anti-theft device can be fixed and opened using special tools kept by a person, which can be completed in a few seconds. Its impact resistance, anti-dramatic, anti-prying, anti-drilling and other functions are super strong, it cannot be opened by any other tools, and has good anti-freeze, rust and other functions.

In addition, it can meet the needs of the existing manhole covers with more than a dozen specifications, and has the function of adjusting according to the size and shape of the compound manhole cover and the thickness and height of the reinforcing ribs.

Now, the new anti-theft device of Fuzhou composite manhole cover has been widely used in many areas, and the effect is very obvious!
