Trench cover plate plays a very big role in the urban and industrial use. For some places with more water and low terrain, we usually drain through the trench cover plate, so the quality of the trench cover plate is very critical.
Standard for trench cover plate purchase:
1, corrosion resistance ability: When choosing the trench cover plate, because the used environment will be relatively bad, so the corrosion prevention requirements will be relatively high. The trench cover plate can last up to 30 years. When choosing trench cover, corrosion prevention requirements will be relatively high because the environment will be harsh. The trench cover plate can last up to 30 years.
2, pressure resistance: the gutter cover plate should have a certain pressure resistance ability, especially in industrial factories, to be able to withstand the weight of the vehicle. Grench cover plate, bearing weight up to 3-5T. Because the trench cover plate should have a certain pressure resistance ability, due to the different use scene of the trench cover plate, try to choose a large bearing weight-some trench cover plate, it is not sure when there will be heavy pressure.
3, drainage hole is clear: the drainage hole of the gutter cover plate is clear, which can ensure faster water outflow, large leakage area, and achieve the effect of fast drainage.
