Sandwich plate system

Not to be confused with sandwich panel.

Sandwich Plate System (SPS) is a structural composite material composed of steel and polyurethane elastomer.

SPS is used in engineered structures including ships, buildings, stadia, arenas and bridges and was invented by Dr Stephen Kennedy following his primary research in the field of ice strengthened structures at Carleton University in Ottawa and first patented in 1996.

The SPS technology is a direct replacement for stiffened steel and reinforced concrete in heavy engineering projects.

The first recorded project involving SPS was carried out on the P&O Pride of Cherbourg, a Lloyd’s Register approved vessel, in 1999 and over 200 projects have been completed to date.
