MANUFACTURE AND ASSEMBLY OF COMPOSITE MATERIALS AND STRUCTURES

WE MAKE YOUR LOAD LIGHTER…

PREFA KOMPOZITY • Brno • Czech Republic

COMPOSITE COVERS

Composite walk-over and load-bearing covers are resin-fiber sandwich or pressed plates, suitable for corrosive and other environments.

References

D400 manhole cover
D400 load-bearing cover
Composite walk-over channel cover
Atypical waterworks cover with composite ladder with top handles
Waterworks cover
Composite green colored covers between tanks

More examples of applications can be found in the references: water management and transport constructions

Details

Walk-over opened-edges cover
Manhole cover DN 600 A15-D400, with composite frame
Walk-over closed-edges cover
Manhole cover DN 600 D400, with composite frame and seal
Walk-over cover for waterworks shafts
Load-bearing covers A15 - D 400

COVER TYPES

By shape:

  • Rectangular – most common
  • Other shapes, e.g. circular – consult our technical staff
  • Manhole covers: DN 600 mm circular only

By design:

  • Closed-edges covers consist of a moulded grating and double surfacing; edges are closed by a U beam frame; walk-over side has anti-slip finish of silicate sand suspended in resin
  • Opened-edges covers use the same design, except not all sides are closed
  • Circular manhole covers are made by pressing

By load:

  • Walk-over covers (maximum load 250 kg/m2)
  • Load-bearing covers of class A, B, C, D pursuant to CSN EN 124:
    • A15 – load capacity up to 1.5 t – designed for areas that are used exclusively by pedestrians or cyclists
    • B125 – load capacity up to 12.5 t – use: sidewalks, pedestrian zones, parking for cars
    • C250 – load capacity up to 25 t – designed for car parking spaces, side roads, sidewalks and pedestrian zones on the streets
    • D400 – load capacity up to 40 t – designed for lanes of roads, paved roads or parking areas, which are accessible to other than passenger cars

KEY FEATURES

  • Low weight (5 x lighter than cast iron)
  • Highly durable, resistant against corrosive environments
  • Maintenance-free
  • Not accepted at salvage yards (lower likelihood of theft)
  • Electrically non-conductive
  • Variable dimensions
