Explore our pioneering SPS® system

At SPS Technology, we solve clients’ problems through the power of collaboration and innovation, via our global offices and the SPS Technology Partner Network in Europe, North America and Asia. Across all of our growing number of sectors, our Sandwich Plate System, SPS, product has developed into one of the world’s unrivalled composite solutions backed up by continuous, cross-application global testing and development.

Our modular structural composite is recognised as the first sustainable major advance in heavy engineering in 150 years. A structural load bearing plate — consisting of two metal plates bonded with Elastocore®, manufactured by partner BASF — Sandwich Plate System is lighter and thinner than conventional solutions such as reinforced concrete.

SPS structural composite panels:

  • simplify and lighten structure;
  • are prefabricated and modular;
  • are sustainable: fully recyclable and reusable;
  • reduce vulnerability to fatigue and corrosion;
  • enhance the damping characteristics of the structure, improving vibration and acoustic performance;
  • withstand extreme loads and absorb impact energy efficiently without cracking, spalling, separation or rupturing;
  • eliminate the stiffening elements required in conventional steel construction;
  • are impermeable to hydrocarbons and cannot absorb any chemicals, so will not degrade, react with or contaminate other substances.

The solid elastomer core provides continuous support to the faceplates, prevents local buckling, and transfers sufficient shear between the faceplates such that their full plastic capacity can be reached in tension, compression, shear, bending, and any combination thereof.

SPS Technology: About SPS

Sandwich Plate System is supplied as individual panels or modular units, with factory fabricated details and finishes. Or, in the case of maritime and offshore projects, SPS can be applied on-site as a low-heat or Cold Work solution to an existing structure for reinstatement or upgrade without interruption to service.

Uniquely, SPS can be used for newbuild structures or to upgrade or retrofit existing structures for enhanced performance or larger footprints. New panels are factory built to very high dimensional tolerances and are ideally suited to modular construction allowing rapid roll-out of building units for a wide range of demanding requirements.

In all cases, the thicknesses of the core and faceplates are selected to meet the particular structural requirements for any specified loads. The elastomeric core bonds the steel – any grade, or other metal e.g. aluminium – faceplates, delivering high stiffness and shares stresses acting on one faceplate with the other so both are engaged in resisting the load.

SPS brings structural simplicity. Compared to stiffened-steel plate, SPS eliminates all secondary stiffeners. SPS also delivers a far lighter and thinner structural element than a conventional concrete slab, which is deeper and heavier.  All SPS panels have an extended fatigue life in comparison to traditional materials. Fully recyclable and reusable, SPS is a more environmentally sustainable solution.

Our history

Sandwich Plate System was developed in the late 1990s at Canada’s Carleton University in response to protecting offshore structures in the Beaufort Sea from impact damage due to ice sheet loads. The solution was a steel-elastomer-steel composite panel, with a high strength-to-weight ratio and durability that would enable the offshore structures to withstand the heavy loads. We have stayed true to our unique design heritage in the offshore industry while forging into specialist markets by expanding our team of industry experts, an approach that has enabled us to develop new uses for Sandwich Plate System while continually innovating across all of our growing number of sectors.

Our growing number of SPS Technology Network Partners can provide more details of how SPS can be used.
