Superiority
1----Anti-theft: cover and base frame integrate connection, hinge-type opening, sledgehammer hit not break it, completely anti-theft.
2----Load-bearing great: the toughness of ductile iron is fourfold that of ordinary cast iron, close to steel materials, suitable for all kinds of road use!
3----Corrosion resistent: Sewer internal environment complex, filled with various chemical substances, ductile iron does not suffer chemical corrosion, service life more than 30 years.
4---- Opens conveniently: light weight, single unarmed can be open, convenient downhole maintenance!
5----Superior safety performance: It often occurred underground explosion accident, fly up covers scarred passers-by , manhole covers integration connections will not depart from the ground.
