Strongwell Corporation Stay-In-Place FRP Bridge Deck System GRIDFORM

GRIDFORM™ is a prefabricated fiber reinforced polymer (FRP) double-layer grating, concrete-reinforcing system with integral stay-in-place (SIP) form for vehicular bridge decks. The system consists of FRP plates bonded to the bottom grating of FRP double-layer grating panels, creating a bidirectional, lightweight panel for the grid construction of corrosion-free concrete bridge decks. The lightweight GRIDFORM™ panel, which weighs only 4.7 pounds per square foot, is shop-fabricated in very large units that are limited only by shipping constraints to approximately 50 ft. by 8 ft. When the GRIDFORM™ arrives on site, it is lifted with a single pick of a crane and placed directly in the bridge girders. The GRIDFORM™ panel is pre-engineered and detailed to enable rapid attachment to the bridge girders and subsequent concrete placement and forming. The anticipated lifespan of a GRIDFORM™ bridge deck is several times that of steel reinforced concrete bridge decks since FRP provides a corrosion-free reinforcement system for the concrete.
