Application
BETTER COVER Through the optimization of SMC composite materials and innovation in product structure, the current rated load of BETTER COVER composite manhole covers is: E600 (60TON)
At the same time, the product is lightweight, and its weight is 1/4 of the cast iron manhole cover of the same grade. Protect the operator's waist health, save installation and maintenance costs, and make work more efficient and easier.
There is a locking sealing inspection sub cover with a net opening of ∅ 350mm（13.8"） in the middle of the manhole cover, which is waterproof
● 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.
● Strong 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.
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.
●Screw locking mechanism
●Tool
We have mature OEM and ODM experience
Customizable logo, cover pattern, color and size
The weight of composite manhole cover is 1 / 4 of that of traditional manhole cover with the same volume
