Clear opening 600x800mm sewer cover:

1.Low noise
2.Fall prevention: this manhole cover design for steel frame,bearing capacity is strong.
3.Prevent slippery: the frame add one rubber gasket.
4.Material: high quality by SMC new material and improve the density of the product, make the product has strong compressive. Bending, impact resistant, heat resistant, cold resistant, Corrosion resistant, acid and alkali resistant, aging, not easy to deformation, etc.
5.Well sealed: it can be used hermetically, and effectively prevent those poisonous gases leaking out from cesspool.
6.No any jangle: There is neither jangle nor rebound when cars pass through.
