More about Sandwich Plate System Bridge Decks

The Sandwich Plate System (SPS) technology has been developed for the heavy civil engineering market and consists of two steel plates bonded to form a sandwich with a compact polyurethane elastomer core. The elastomer provides continuous support to the steel plates and precludes local plate buckling and the need for stiffeners. The flexural stiffness and strength of the sandwich plate is tailored to meet particular structural requirements by selecting appropriate thicknesses for the sandwich elements. The SPS Bridge Deck product has been used successfully as an alternative to conventional concrete and orthotropic steel deck.
