In real life, the phenomenon of stolen manhole covers is often found, mainly because the strength and cost of traditional manhole covers are relatively high, and there is a certain recovery value. However, if it is changed into a composite manhole cover, the anti-theft property will definitely be improved, which will be beneficial to the application of the product.
Due to the special nature of the raw materials, the strength of the composite manhole cover has also been significantly enhanced, and the anti-theft performance has become better because it does not contain any iron. After comparing various manhole cover products, we found that the comprehensive performance of the compound manhole cover is between the stone plastic manhole cover and the concrete manhole cover, so it is more suitable for occasions that require more manhole cover technology.
The composite material itself has good physical and chemical properties, so the processed composite manhole cover will also be very ideal in these aspects, lubricity, heat resistance, fatigue resistance, etc., to ensure the function of the manhole cover.
