In the construction process of modern cities, complex lines and pipelines such as power systems, optical fiber cables, water pipelines, etc. are shuttled from the ground to each household. In this process, it is inevitable that maintenance protection and other issues will be involved. Many openings will be left on the ground to facilitate future repair operations, so that manhole covers will be born.

On the basis of the manhole cover, our composite manhole cover has emerged through the efforts of countless people and professional transformation. The composite well cover has the advantages that previous well covers do not have. It can be applied in all places, and has long service life, excellent quality, and no maintenance problems. The function of composite manhole cover is becoming more and more diversified, which makes its development more and more powerful. Composite manhole cover is frequently used in municipal administration and buildings.

Most of the composite well covers sold on the market now have the characteristics of corrosion resistance, strong compression resistance and large bearing capacity. More importantly, the materials he selected in the manufacturing process are cheap and easy to obtain, and the total manufacturing cost is very low. The composite well covers have no steel structure. The whole cover body is made of new materials, which has no recycling value, In this way, the theft of the composite manhole cover is greatly avoided. It is often reported that the manhole cover is stolen somewhere during the use of the steel casting manhole cover.

The composite well cover has very strong anti-corrosion ability. Its ex factory standard is that the quality loss is not more than 1% after being soaked in sulfuric acid for 48 hours. It is conceivable that its anti-corrosion ability is so fierce that people do not have to worry about the damage to the composite well cover caused by prolonged sun exposure and rain, so that the well cover is vulnerable to brittle damage, resulting in accidents. The ability of composite well cover in compression bearing is tested by professional software, and it is forged by using new high molecular materials under high temperature and pressure, which can bear more than 40 tons.
