Steel base plates provide the foundation for ground-supported truss structures where maximum stability and reliable load transfer are non-negotiable. When a production is large enough to use 12-inch or 20.5-inch plated truss overhead, the ground support system needs to match that capacity — and steel base plates are built to handle it.

The plates sit flat on the floor surface, distributing the vertical load of the truss system across a wide footprint. A bolt pattern on the top face accepts the upright or base cup of the truss system, keeping the structure plumb and secure throughout the load cycle. For temporary production use, no floor anchoring is required — the weight of the system keeps the plates in place.

Truss Genius carries multiple sizes to match the system you're building. Steel base plates are compatible with 12-inch and 20.5-inch plated truss systems as well as the EVT290 series, making them a versatile foundation component for any large ground-supported structure. Production companies speccing concert stages, arena builds, and long-span overhead systems will find the selection here covers the most common base requirements.
