In 2016 SHS introduced their new Fibreglass Reinforced Plastic (FRP) Composite Bridges, therefore a completely new production line has been built at our factory.
The bridges are built upside down in specially prepared moulds, layers of reinforced fibreglass mats are placed around foam formers and then resin is inserted by means of vacuum infusion. This technique pulls the resin under pressure to form the desired composite bridge design.
After curing, the bridge is taken from the mould and finished with an anti-slip layer and the chosen parapet is installed. The parapet can be constructed in wood, steel or composite. The bridges are suitable for pedestrians and cyclists and can be designed to carry the five ton vehicle load referred to in the Eurocodes.
The new Fibreglass Reinforced Plastic (FRP) Composite bridge can be equipped with different sensors that measure for example, the temperature for gritting and salting in winter months, it’s own frequency, deformation and applied loadings.
Upon reading the sensors the real time stresses, strains, performance and condition of the structure can immediately be seen. It can also be established if the bridge is being overloaded.
These measurements are transmitted via a Wi-Fi connection to a computer. The dashboard of the database allows this information to be tracked live. These sensors can, at extra cost, be built into the composite bridges.
With the production of Fibreglass Reinforced Plastic (FRP) Composite, SHS has expanded it’s product range and we can now advise on the different materials that produce the perfect bridge structure for any environment. Timber, steel, composite or a combination of these materials! The choice is made on the basis of, the mechanical characteristics of the particular bridge, the price, the expected lifetime, the maintenance costs and sustainability issues.
