Iron Bollard Installation: Modern Methods and Site Considerations

Selecting the right iron bollard is only half the process. Proper installation is essential for both performance and compliance. Here’s what Chicago-area property owners should know:

Primary Installation Techniques

• Embedded (In-Ground): Bollards are set into concrete foundations for maximum strength and security.
• Surface-Mount: Fastened to concrete or pavement using anchor bolts—faster to install but not as impact-resistant as in-ground options.
• Removable: Engineered sleeves allow posts to be unlocked and temporarily removed.

Factors That Affect Installation

• Soil type and paving thickness (affects stability and depth requirements)
• Code requirements for height, spacing, and setbacks—these can vary in the Chicago, Illinois area
• Drainage design (to avoid rust or concrete cracking)
• ADA compliance needs (especially in public walkways)
