SPS Technology’s Sandwich Plate System

SPS^®: a Structural Revolution

Across multiple industries

At the forefront of structural engineering, SPS Technology introduces a revolutionary solution – the Sandwich Plate System (SPS). This proprietary structural composite material, comprised of two metal plates bonded by Elastocore^Ⓣ, has become a hallmark of safety, speed, durability and strength in construction.

The History and Evolution of SPS

SPS has a rich history spanning three decades, with roots in addressing challenges in the offshore industry. Originating as a response to the limitations of conventional stiffened steel and pre-cast concrete, SPS has become the cornerstone of construction innovation, contributing to the creation, enhancement and retrofitting of structures across diverse industries.

Our SPS timeline showcases a journey from the pioneering use of concrete core sandwiches in 1992 to the cutting-edge solutions provided by the SPS Technology team today.

We develop and deliver innovative first-of-type applications across all of our markets

SPS is more efficient than steel or concrete

SPS offers a versatile solution applicable across various sectors, adapting to diverse structural needs and making it the preferred choice for civil engineers and architects globally.

As such, our innovative composite has expanded beyond its offshore origins to applications in maritime, bridges, stadiums, arenas, buildings and special projects, including threat protection.

Prefabricated and modular solutions demonstrate the system’s adaptability and efficiency in addressing complex structural challenges.

Extreme Versatility

From fluid forms to bold angles, SPS is transformable and easily customised to virtually any shape. Our composite can reach where other materials can’t and can be customised to have any shape or thickness to meet project capacity requirements.

Exceptional Efficiency

SPS operates on a similar principle to an I-beam but in 2D. Bending moments generated by pressure loads are managed by the faceplates, which are set apart by the elastomer core. This setup generates a larger moment of inertia, making SPS remarkably lightweight yet robust.

Positive Impact

For the same capacity, SPS terraces, floors and decks are up to 40% lighter than other conventional materials like concrete. This means that all other supporting structures have to carry smaller loads and can, therefore, also be smaller/lighter.

Impact Protection

The composite panels are very efficient at spreading out loads from impacts and blast events, making SPS more efficient than conventional materials as it engages a larger area to resist the loads.

Sustainable Construction with SPS Technology’s Sandwich Plate System

SPS Technology’s design philosophy centers on sustainability. All SPS elements are developed with the environment in mind, offering a product designed for reuse and recycling. Prefabricated, modular components reduce on-site assembly time, decrease carbon footprint and enhance safety.
