Calculate the Total Cost of Ownership (TCO) rather than just the initial purchase price. While flexible polymer barriers have a higher upfront cost, they offer better ROI by reducing floor damage and eliminating the need for repainting after minor impacts. Conversely, steel barriers are more cost-effective for permanent, high-segregation areas but require more maintenance. Consider modular designs which allow for the replacement of single damaged rails rather than the entire system, significantly lowering long-term maintenance expenses.
