Fixed post bollards are the most commonly used and are ideal for any application from simple traffic control to the toughest perimeter defense needs. These bollards create a physical barrier to protect pedestrians and buildings from oncoming vehicles while allowing free movement in between the bollards. Embedded bollards with a properly engineered footing offer the most dependable protection and are offered in carbon steel and stainless steel. Carbon Steel Fixed Bollard (IBF Series) The IBF series of fixed post bollards are manufactured from carbon steel for a variety of strengths and options.
