        ELECTRICAL  STEEL  FIBER  MANHOLE  COVER   FEATURES

1.High  strength

Ordinary concrete and the small amount of low carbon steel, stainless steel and glass fiber.

 

2. Anti-shock

 only through the mouth of the Manhole set to U-shaped, with a T-type synthetic rubber, U-shaped slot embedded in the contact Manhole covers and the process in order to cushion and reduce the vibration force.

 

 3.. Anti-slip:

3mm tread covers convex surface, and thus play a good non-slip effect.

 

4. Anti-impact:

 Manhole covers the contact with the colossal surface, directly on the T-rubber, and dealt with gently, to eliminate noise

5. Good  ability

Tensile, bending and strength is good; the impact toughness of high compressive strength, shrinkage is better, anti- fatigue, durability,
