By improving the mechanical properties of the material and optimizing the structural design, the manhole cover and the well seat have a high degree of fit, a stable structure, and small deformation. The product will not produce deformation, displacement, or cracking during installation and use.
BETTER COVER's independently developed SMC composite material has high density, low water absorption (0.15mg) and good waterproof properties.
At the same time, the design of the sealing ring and structure achieves good sealing performance.
