Duplex Honeycomb Conveyor Belt


Duplex Honeycomb Conveyor Belt

Conveyor Belt

Duplex Honeycomb is an ideal choice for any application which requires both durability and an open belt design, whilst maintaining a flat carrying surface. The Duplex arrangement of the castellated flat strip and increased cross rod size gives the belt high strength-to-weight ratio which makes it an ideal choice for customers having heavy loaded applications with a high demand for efficiency of operation.

Duplex Honeycomb belting, also known throughout the industry as Duplex Flat Wire belting, is a straight-running belt with an extremely high strength-to-weight ratio. It is available in a single standard specification having a nominal aperture size of 21mm wide x 26mm long.

Duplex Honeycomb is constructed from twin sets of formed flat wire strips connected by cross rods running through the width of the mesh. The duplex arrangement of flat wire strips having a 22.23mm depth produces a very stable belt construction. The cross rods are finished at the edges with a welded washer or nut.

The belt has a very high strength rating and is positively driven by means of specially developed sprockets. The large open area with high strength makes this belt particularly suitable for processes such as the handling of castings or similar in both hot and ambient conditions.

  • Open mesh construction for quick drainage and free air circulation
  • Flat carrying surface
  • Easily cleaned
  • Easily joined
  • High strength to weight ratio
  • Positive sprocket drive
