FlexRack Series B (Ballasted) Pre-Cast

The FlexRack Series B pre-cast system employs a front-rear post design, rather than the one-support system used by many of our competitors. This innovative two-member support system effectively transfers loads into the block through two supports instead of one, allowing us to reduce ballast block thickness and overall system costs.

  • Cast-in channels without weldments allow for quick assembly and adjustability on the jobsite, significantly reducing installation costs.
  • Lower concrete and steel costs: Requires fewer components and fasteners.
  • Lower array profiles provide flexibility in ground clearance.
  • Accommodates low bearing pressure sites: The two-support system allows a front-back ballast block arrangement where appropriate. Hence lighter lifting machinery can be used when low bearing pressure requirements exist on the job site.
  • Compatible with all Solar FlexRack ground racking systems, pre-assembled at our factory, or field assembled.
