Heavy duty manhole covers-D400 manhole cover、E600 manhole cover

Heavy duty manhole covers are usually used in areas with heavy traffic. Therefore, the load-bearing and anti-theft capabilities of the manhole cover must be good enough. The composite manhole cover fundamentally solves the problem of theft. It is made of glass fiber and other reinforced materials, which is solid and durable, and has no recycling value! If the manhole cover is lost, it may cause traffic accidents and personal injury. Our heavy-duty manhole cover has a hinge structure, which completely avoids the possibility of manhole cover separation. And can be locked, not only can protect the equipment in the well, but also prevent the risk of safety accidents caused by the manhole cover being opened at will. With multiple security guarantees.

For private gardens or hotel areas, the airtightness of manhole covers is very important. The unpleasant pungent smell of the sewers affects people's comfort. The Jinmeng composite heavy duty manhole covers have a double-sealed structure and have very good airtightness.

Our manhole covers provide private customization services so that your manhole covers have unique non-slip patterns and eye-catching company logos. In areas with a large flow of people, such as gas stations, non-slip manhole covers can prevent people from slipping when passing through the manhole cover. A custom logo can distinguish the ownership and type of drainage systems in public areas. The design of the manhole cover is humanized. Some manhole covers have drainage holes on the upper part of the cover to avoid water accumulation.

Our Heavy duty manhole covers do not only have round but also have rectangular and square. Adapt to various environments and corners. Compared with cast iron manhole covers, composite manhole covers are easier to move and are easy to install, maintain and transport. For heavy manhole covers that require frequent maintenance, the heavy-duty manhole cover with a hinge structure greatly improves the maintenance efficiency and avoids injuries caused by lifting the load-bearing manhole cover. The heavy-duty composite manhole cover has a good signal transmission function and will not interfere with radio frequency signals even in the manhole.
