∅600mm(23.7") D400_Sealed composite manhole covers and frames

Application

• Freight station
• Wharf
• Gas stations
  
• Other heavy roads and sites frequently used
  
• Sewer
  

● Strong corrosion resistance and anti-static

● Strong Sealing Performance

The oblique cut design of the sealing ring has a large contact surface, increasing the sealing strength.
High fit of manhole cover and seat, stable structure and tiny deformation.




BETTER COVER’s independently developed “T-SMC composite material”

T-SMC Material advantages
T: Stands for extremely high glass fiber content, which means it`s more than 45%,Ensure glass fiber is fully soaked in resin through special process



T-SMC Material production line
To strictly control the ratio of raw materials, digital metering is been adopted,which can achieve high accuracy, i.e.within 50g.

●Waterproof and non-slip

Because the upper surface of the manhole cover is a raised bridge structure, it can effectively prevent the accumulation of rainwater on the surface of the manhole cover. The anti-skid ability of the surface of the manhole cover is greatly improved.

Constantly strive for perfection

●Screw locking mechanism

●Non-slip

The upper surface of the manhole cover is designed with many round bumps with a height greater than 4mm, which increases the friction area on the surface of the manhole cover. The anti-skid ability of the surface of the manhole cover is greatly improved.
