∅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

Manhole covers to have higher corrosion resistance and anti-static.
The high-performance resin, glass fiber and special production process formula used in composite materials ,chemical resistance (acid, alkali, salt, organic solvent, etc.),which has better corrosion resistance and can better resist chemicals. corrosion and reduce the risk of accidents.

● 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.
