SSE has experience in more than 49 states in the US and Canada. In 2015, through a licensing agreement with an international partner, SSE is expanding our practice to include select locations in Europe.
The PREFOAM Stadium Seating Riser System is a proprietary design by SSE using a unique “kit of parts” with PREFOAM EPS Geofoam structural blocks as a base and Gauge Cold or Hot Rolled Steel as a forming system with a concrete topping slab.
Installed late in the construction sequence the PREFOAM Stadium Seating Riser System permits subcontractors to do all the vertical “high work” in the auditoriums prior to installation of the stadium seating thereby saving time & labor dollars.

PREFOAM System Characteristics

SSE has Regional manufacturing and distribution hubs for system components and when combined with the recyclable nature of EPS Geofoam and Steel components, these facts make the PREFOAM Stadium Seating Riser System an ideal environmentally responsible solution to your building needs.
Because components are prefabricated and the system comes with detailed installation shop drawings, a contractor can easily install the system with a team of semi – skilled labor.
The PREFOAM Stadium Seating Riser System is a kit of parts made of readily available materials. It is assembled in the field by cost efficient labor and can cut weeks of time and money off of a construction schedule. Typically cutting 10-20% of costs when compared with traditional light gauge metal framing.
