Infrastructure is a major growth sector for the composites market. Demand is driven by the need for materials that deliver unlimited design flexibility and are lighter, stronger, more corrosion resistant and require less maintenance than traditional structures made from steel and concrete.
For example, in bridge construction, lightweight pre-fabricated modular bridges are replacing steel and concrete structures – especially for bridges designed for pedestrians or bicycles. They are more quickly and easily assembled requiring less road or rail closures.
Fibreglass composites are also used to rehabilitate sewer systems using the latest in trench-free relining technology. Other applications include, corrosion-free concrete reinforcing bars, acoustic barriers and road signs. Theft of steel road signs for their scrap value is a growing problem that Glass Reinforced Plastics products do not face.
