For high-risk areas, IronFlex’s rebounding column protectors are some of the strongest on the market. Unlike plastic barrier guards that slide down a column, IronFlex uses patented rebounding technology to combine four bollards into integrated protection for critical columns. This not only makes them stronger and more durable than plastic models, but it also reduces any impact on building foundations. IronFlex’s column protectors can be configured for a range of column sizes and masses, making them suitable for many environments.
