BRIDGES
Bridge decks built for a
100+ year design life
Prefabricated structural composite SPS is a bridge deck and orthotropic deck overlay solution for bridges, new or old.
SPS bridge decks are custom-tailored to fit all project specifications with great dimensional accuracy. Cost-effective, pre-coordinated SPS bridge decks reduce weight, construction time and the need for future maintenance.

Construction Benefits for
New Build Bridges:
- Architecturally versatile.
- Adaptable to reconfiguration in the future.
- Many wearing surfaces applicable to suit design.
- Sustainability advantages over traditional materials.
- Fully customizable and able to accommodate cambered girders, geometry variations in slope and curvature, railings, etc.
Refurbishment Benefits for
Historic Bridges:
- Overlay strengthening can be used on existing bridge decks to reduce stress ranges, increase structural capacity, and improve fatigue performance.
- Used for renovation, upgrading, strengthening and widening existing bridges.
- Eliminates and minimises the need for demolition.
- More environmentally friendly.
Light
SPS offers up to a 64% reduction in deck weight compared to a concrete deck of the same capacity.
Strong
SPS does not crack or spall like concrete. SPS has outstanding bending moment, shear, buckling and fatigue performance. Maintains or improves damping.
Customizable
Deliver new shapes or reinstate historic bridges with architecturally versatile SPS. Able to accommodate skewed and cambered geometries. All projects coordinated through Tekla modelling.
Cost Efficient
Prefabricated, modular SPS bridge decks arrive on-site ready to be installed. Fewer truck movements, lighter plant and less labor required!
Proven
Backed by decades of testing, research and experience in some of the toughest environments on the planet.
Utilizing the steel-core bond interface, SPS bridge deck panels are effectively insensitive to fatigue.
SPS bridge reinstatement on ageing Ohio rural infrastructure.
The Cannelville Road Bridge in the village of Roseville in Muskingum County, Ohio was the first bridge in the U.S. with modular decked beams consisting of Sandwich Plate System (SPS) deck panels on Press-Brake-Formed Steel Tub Girders. In May 2017 the 52.5-ft-long and 24-ft-wide single-span bridge replaced the existing deteriorated bridge in 26 days, ahead of the 30-day maximum allowed closure.

Build a better tomorrow with SPS – the sustainable solution to bridge deck construction.
All SPS Technology building elements—everything we make for vessels and assets, stadiums and arenas, pedestrian and vehicle bridges, and buildings—are developed with efficiency, sustainability and fire performance in mind.
- improve construction programme by reducing lift times.
- carry loads and equipment immediately (once placed and bolted to).
- allow for easier and faster fixing of additional components, reducing the number and duration of trades on site.
- eliminate extra waste products on site.
- allow earlier completion dates to be met.
Applications
New Roadway Bridges
New Roadway Bridges with SPS Technology.
Tailored to provide the required dynamic and diaphragm performance that satisfies acceleration limits associated with vibrations due to vehicular loads. Standard details – including deck girder connections, expansion joints, drains, guardrails, crash barriers, abutments, and integral curbs – are integrated into the design.
In new build projects, SPS bridge deck facilitates:
- Lighter girders,
- Longer spans,
- Lighter piers,
- Fewer piles per pier,
- Design life up to 100 years.
Orthotropic Bridge Deck Strengthening
Orthotropic Bridge Deck Strengthening with SPS Technology.
SPS can be used to strengthen existing orthotropic steel bridge decks without replacement. The existing deck is used as one plate of the new composite, which stiffens the deck, reduces fatigue stresses, and spreads wheel loads over a larger surface area.
Strengthening is a four-stage process that combines in-situ steel work with elastomer injection in a predictable and repetitive procedure that can strengthen over 200㎡ of bridge areas per day, per crew, without fully closing the bridge as one lane is completed at a time.
SPS bridge decks are up to 70% lighter than concrete and are fully compatible with existing bridge components and wearing surfaces. Standard design procedures to upgrade a bridge are used to tailor the geometry and performance of each SPS bridge deck as a full replacement for old, cracked concrete or open grid decking for bascule and lift bridges, lowering stresses in the existing structural frames.
Reduction in deck dead load for deficient bridges assists with:
- life extension.
- elimination of traffic load restrictions.
- increased load capacity.
- minimising, or eliminating the need for reinforcement.
New Pedestrian Bridges
New Pedestrian Bridges with SPS Technology.
SPS is tailored to provide the required static and dynamic performance satisfying acceleration limits associated with footfall-induced vibrations. Like highway bridge deck construction, pedestrian bridges with SPS are designed for a longer life of up to 100 years.
Material Options
Material Options with SPS Technology bridge construction.
SPS bridge deck panels are manufactured in a wide range of steel alloys that include standard structural steel and weathering steel. For enhanced corrosion protection, stainless steel is another choice used primarily for architectural purposes on pedestrian bridges.
Crash Barriers
Crash Barriers with SPS Technology.
Crash barriers on SPS bridge decks have achieved a TL-4 performance level as verified by pendulum tests conducted at the Texas Transportation Institute. Standard DOT guardrail systems (deck or side mounted) are easily accommodated.
