Sui Generis International provide bespoke FRP components for first-in-the-UK railway footbridge solution on behalf of Network Rail

Network Rail have led a new innovative project to develop and deliver the UK’s first fully modular, FRP (Fibre Reinforced Polymer) footbridge. Officially opened in January 2023.

Turning traditional methods on their head, the vision for the FLOW bridge was modernised by using a modular system made from FRP composites, a polymer matrix (typically a resin) reinforced with fibres made of glass, carbon, or aramid.

Following design and development, Sui Generis manufactured and supplied the main bridge structure, including the modules that form the bridge walkways, the stair inlays, and sidings...

FRP modules manufactured off-site.

Modules manufactured off-site

The modularised system also allows for most of the materials to be manufactured off-site, reducing the pressure on installation teams and disruption of passenger services and track closures.

Rail bridge installation in half the time.

Installation in half the time

Installation of the footbridge can be done in half the amount of time it would take for a traditional in-situ produced steel structure.

FRP Fibre Reinforced Polymer is lighter and highly cost effective.

Lighter and highly cost effective

Composites are up to 70% lighter than steel and have a high strength-to-weight ratio. This considerably reduces transportation and installation costs, making FRP an ideal solution for a rail footbridge.

GRP fibreglass bespoke mouldings – a Sui Generis guide

Glass-reinforced plastic (GRP) is a versatile material that can be moulded into almost any shape. Because it's corrosion-resistant, impact-resistant and hard-wearing, it's the ideal material for a wide variety of applications – industrial, architectural and commercial.

The chemical resistance of fiberglass makes it great for manufacturing storage tanks and tank lids, while its hard-wearing nature makes it a long-lasting cover for pits and machinery.

Its light weight and high strength make it handy for auto parts and it can be finished to resemble traditional materials like stone or ceramic for architectural purposes.

Increasingly, it is being used to create modern, colourful furniture both for offices and outdoor areas.

Sui Generis can mould almost any shape from standard or custom designs and give it the colour and finish you want.

What kinds of structure have you moulded in GRP?

We've moulded everything from a regular supply of cab roofs for Luton Transports to a bespoke architectural moulding for a Victorian building. These are just a few examples of the structures we can create from GRP moulds:

  • Replica chimneys, funnels stone cornicing and turrets
  • Cab roofs, spoilers and cab fittings
  • Tank roofs and covers
  • Storage tanks
  • Enclosures, cabinets and standalone housing
  • Desks and fascias
  • Benches, chairs and garden planters.

Why use fibreglass mouldings?

Because they offer strength durability and resistance – which means they're safer, more secure and will last longer, saving you money over time.

When you order a fibreglass moulded storage tank or tank roof, it will be chemical-resistant, corrosion-resistant and weather-resistant – and can even be customised to suit its contents.

Likewise, the colour and vibrance of our moulded seating and furniture won't fade, crack or perish – making every piece a low-maintenance investment purchase you'll use for years.

With all these great benefits, no wonder more and more structures being moulded out of GRP fibreglass.

Are there other benefits to moulded fibreglass?

There are many. These are just some of the properties of GRP moulds:

  • Corrosion Proof
  • Chemical resistant
  • Leak free
  • Impact resistant
  • Indefinite lifespan

Do your fibreglass mouldings conform to regulations?

Yes. All our fibreglass moulded products are manufactured to strict quality standards and use only high quality materials.

Because they need to be ready to house chemicals, oil and other liquids, our storage tanks comply with current Pollution Prevention Guidelines (PPG2) and SEPA (Scottish Environment Protection Agency) regulations.
