A brief introduction, trench cover

The drain cover is also known as trench cover plate, trench cover, it adopts the steel grid plate welding, installation has the advantages of simple construction, light weight, good impact resistance, bearing, Ning Wan do not fold, the displacement of large, after galvanizing after treatment with beautiful and durable, corrosion and rust cast iron ditch cover, has incomparable advantages. Because the steel grid plate adopts the hinge connection mode, which is convenient for opening.

Two, ditch cover the production standard

4: Design of the cover and frame with a hinge or shackle connecting, safety, convenient opening.

5: save the investment of project cost is lower than the cast iron; and can save the cast iron cover was crushed and replacement costs.
