    Features

     

    Anti-Slip surface
    DSD Manhole Cover’s top surface material has a better slip-resistance value in a wet, dry or worn state to increase safety.

     

     

    Watertight Seal
    Integrated cover creates a watertight seal between the cover and frame.

     

     

    With Central Inspection Port Cover
    There is a locking sealing inspection port cover with a net opening of ∅ 350mm(13.8") in the middle of the manhole cover, which is waterproof 

     

    Material
    frame and inspection cover are made of SMC FRP composite material. The removable side sealing structure adopts corrosion-resistant EPDM rubber, the aluminum sleeve of removable sealing handle adopts aluminum alloy, three m10x40 hexagon socket head locking screws adopt 304 stainless steel, and the locking mechanism of inspection cover adopts aluminum alloy and 304 stainless steel 

     

     

    Lockable
    Lockable access covers not only improves site and location security and provides security against theft and malicious damage.

Q & A

Q

What is SMC materials?

A

SMC composite is a short form of “Sheet Molding Compound”. It’s composed of resin, fiberglass and other chemical polymers, it’s homogeneous material and often used in aerospace composite structures.

The outstanding advantages of SMC composites:

  1. It can maintain good dielectric performance under high frequency, and does not reflect or block the microwave. It is suitable for application in crowded or narrow places, and can effectively avoid the danger of electric shock.
  2. It has effective resistance to water, gasoline, alcohol, electrolyte salt, acetic acid, sodium potassium compounds, asphalt, acid base soil and acid rain corrosion.
  3. Under the combined action of three-dimensional network molecular structure and reinforcing fiber, the material has good impact resistance, easy to be machined, easy to drill and cut, and accurate positioning.
  4. It has strong impact resistance to avoid deformation, with high tensile strength, bending strength and impact toughness.
  5. As a smokeless and non-toxic materials, it does not contain halogens, and it’s an environmentally friendly material that can meet the needs of future development.
  6. The fire retardant can reach to FV0 level, and the smoke & gas level is quasi-safety level 1 (ZA1), which meets the requirements of domestic and international UL94 standards.
  7. It’s poor conductor of heat, has low deformation rate of high-temperature resistance which can reduce the influence of environmental temperature difference on the internal structure of products.
  8. It’s able to adapt to any kind of harsh weathers, it can be used in the climate of -50°C - +160°C for a long time. The protection level is IP54, which can maintain good physical and mechanical properties.
