In people's daily life, trench cover plates are very common. The key to its effect is to prevent non-motorized vehicles and automobiles from falling into the sewer. Together, it can facilitate the smooth discharge of ground water. In addition to the concrete materials that people usually see, what other materials are there? Zibo Best will explain to you.

 1. Cast iron

The trench cover commonly used in big cities is cast iron. The trench cover made of this raw material has a strong bearing capacity, and there is no problem with non-motor vehicles or large, medium and small vehicles. However, cast iron cannot be used in areas with strong pH correlation, such as some pharmaceutical factories. Because steel is prone to exothermic reaction in this area, it is becoming more and more durable, increasing maintenance costs.

2. Composite resin material

Composite resin is suitable for use in areas with strong acidity. The epoxy resin trench cover is very light and easy to install. The trench cover plate made of new composite resin is no less than high-carbon steel and has stronger corrosion resistance. Therefore, the composite resin trench cover is a common method for many pharmaceutical factories and sewage treatment stations to solve acid and alkali wastewater.

Before choosing the trench cover, people must understand the characteristics of the material to ensure that the cover can give full play to its use value in the whole process of practical application.
