Security Bollard || November 14th
Ligman offers a comprehensive range of traffic rated security bollards. This optional design includes a 1/4" wall thick galvanized steel security pole with 2 solid 1" galvanized steel cross support rods that are embedded into concrete. These security bollards provide restraint of vehicular traffic in unauthorized areas. Impact studies show that Ligman's security bollards can stop a 5,500 lb vehicle travelling at speeds up to 30mph. For additional strength, the galvanized pole can be filled with concrete up to the waterproof driver housing to provide a solid concrete barrier.
