What are the types of sewage tank covers?

Reverse hanging membrane cover plate: The membrane material in the reverse hanging membrane of the sewage tank is a polyester fiber material, and the membrane material of the reverse hanging membrane of the sewage tank is composed of two parts: a substrate and a coating. Suitable for covering the span of various types of sewage tanks, the larger the area, the lower the cost; It relies on the strong tensile strength of the anti hanging membrane material itself and is used to make anti hanging membrane for sewage tanks. It is widely used for sewage tank capping, breaking through the linear design concept of traditional sewage tank capping structures. The curved design characteristics of the anti hanging membrane design for sewage tanks are undoubtedly revealed, and it is a modern structural design that has excellent sealing effect for sewage tank capping, novel appearance structure, and beautiful shape.

Fiberglass cover plate: Fiberglass cover plate is also the most common sealing process in sewage tank capping, which mainly relies on materials such as resin to make curved cover plates; However, there are limitations on the span of sewage tanks, which are mainly applicable to sewage tanks with a span of less than 20 meters. The fiberglass cover plate is prone to aging and embrittlement due to prolonged sunlight exposure, leading to air leakage and collapse.

Stainless steel cover plate: The stainless steel cover plate is a sealed structure supported by stainless steel plates and steel pipes, which is costly and difficult to replace in the later stage; The larger the span of the sewage tank cover, the higher the cost.
