Various design options available including (but not limited to) horizontal rail, spindle infill, and hybrid material options. (consult parapet data sheet for more information)

ReLife 40

The ReLife 40 Pedestrian Bison Bridge system is a low maintenance, long life standardised modular bridge system produced from recycled plastics. It is designed to the Eurocode and DMRB standards for safe access for pedestrians and disabled users.

Features and benefits:

  • 20 year warranty.
  • 40–50 year desired service life.
  • Manufactured from a blend of 100% high quality recycled plastic residue from post industrial and commercial usages.
  • 100% recyclable at the end of its service life.
  • Bison recycling take back scheme.
  • UV resistance tested in accordance with ASTM D790.
  • Slip resistance tested (SRV & PTV to the BS 7976 standards).
  • Fire retardant (Class B2 DIN 41+02).
  • Solid composite board.
  • No maintenance: unlike timber, it won't warp, splinter, or rot and is unaffected by pests or wood boring insects.
  • Colour: dark brown (variation black).

SureGrip-Duo European Redwood

The SureGrip-Duo European Redwood Pedestrian Bridge system is designed as an aesthetically pleasing bridge system with a similar aesthetic to that of a traditional timber bridge.

SureGrip-Duo timber deck boards have a double strip of bauxite resin routed in each board. These strips considerably reduce the risk of injury in wet or slippery conditions.

Features and benefits:

  • 15 year desired service life.
  • UC4 treated timber.
  • Slip resistance tested (SRV & PTV to the BS 7976 standards).

SureGrip-Duo Ekki Hardwood

The SureGrip-Duo Ekki Hardwood Pedestrian Bridge system is designed for extreme strength and longevity. Ekki hardwood contains natural oils and tannins that make it highly resistant to decay, rot, and insect infestation.

SureGrip-Duo timber deck boards have a double strip of bauxite resin routed in each board. These strips considerably reduce the risk of injury in wet or slippery conditions.

Features and benefits:

  • 50 year desired service life.
  • Slip resistance tested (SRV & PTV to the BS 7976 standards).

Perforated steel

Perforated galvanized steel deck boards are the perfect choice for areas of high vandalism. Designed for longevity, vandal resistance and excellent anti-slip surface.

Features and benefits:

  • Bison recycling take back scheme.
  • Perforated steel holes @ 5mm Ø designed to be dog claw proof (safe for pet use).
  • Slip resistance tested (SRV & PTV to the BS 7976 standards).
