Security Bollards
Traffic Bollards Come in Four Main types
Security Bollards are specifically designed for its purpose and has its own benefits and limitations. Within these groups, there are sub-groups. Also, bollards that fit in those categories can also fall into other sub-categories less dependent on function and more on aesthetics.
Architectural Bollards might be any of the above, but are also designed to also include pleasant or unique shapes. A Lighted Bollard is simply a bollard with a light source built in either to add conspicuity to the bollard or to light the surrounding area.
Four main types of Traffic bollards:
- Embedded Bollards
- Surface Mounted Bollards
- Surface Mounted Bollards
- Retractable / Removable Bollards
Certain types of bollards discussed are more or less appropriate for each application, depending on the required function.
Shallow Mount Bollard
An anti-ram system and method of construction having a shallow mounted base pad from which extend a plurality of bollards. Very little or only a shallow excavation is required for the base of the bollard system, which can be partially or fully assembled prior to bringing it to the installation site. The shallow mounting pad or base of the bollard system of this type may be formed or constructed in various ways and of various materials, and in various configurations. The shallow mounting pad or base is constructed so as to have considerable mass. The system has been designed and tested showing it meets the requirements and achieved a successful certificated rating.
Surface Mounted Bollards
This type of bollard uses some sort of anchor system, usually mechanical, to mount the bollard to the surface. Although this is an inexpensive method of installation, it also is not a very secure method. Upon impact, the anchors are often the weakest link and quickly give way, leaving a tilted bollard and damaged foundation. However, when the purpose of the bollard is more to provide a mere presence or psychological barrier, this type of installation is most cost effective. It also may be necessary to use shear bolts in a post-tensioned concrete structure in order to prevent impact to the bollard to potentially compromise the building.
Embedded Bollards
Embedded Bollards are simply bollards which are embedded deep into the ground. This is usually for added strength and security. Embedded bollards can be made out of any common bollard material, be it steel, concrete or even wood, however the bollard will only be as strong as the foundation in which it is buried. A steel post filled with concrete and buried very deep within a reinforced concrete foundation will be strong indeed. On the contrary, a wooden post buried in soft sand or dirt will not provide as much protection.
Costs for this type of bollard can be significant when coring out existing concrete or asphalt surfaces. It also potentially weakens the foundation, and therefore may not even be appropriate in an application such as a structural concrete parking deck. On the other hand, when placing a bollard in an unpaved area, this is perhaps the least expensive and simplest approach.
Retractable / Removable Bollards
Not all applications for bollards are intended to be permanent or always prevent access. As such, retractable and removable bollards have been designed to allow the owner or a potential traveler access the area normally denied by the bollard.
This is typically done in one of several ways. The lowest technology is the pipe-in-a-tube method where a socket is created in the ground. The bollard can then be removed from the socket when access is to be granted. This is inexpensive, but requires manual intervention to access the area. A second way is through the use of pivoting bollards. A locking pin is used to hold the bollard upright under normal circumstances, and removed to allow the bollard to lay flat when a vehicle is to pass over it. These bollards are generally flat in shape to allow for vehicle clearance. Often, the pin is locked in place with a padlock to prevent unauthorized access.
Finally, the most expensive method is the automatic retractable bollard. Usually hydraulic powered, the bollard actually retracts straight down into the ground and becomes flush with the surface during access. Actuation of a hydraulic bollard can be by any number of methods, from security guard push button to remote controls and toll booth pay systems.

Client Testimonials
Paul and his team are excellent at addressing challenges thrown at them. They do not make excuses on why things cannot be done; they solve problem for you by doing what can be done. When we were in a bind, Paul would throw resources at our project to make sure we were successful. Their attitude is a great fit for our high-visibility and high-maintenance project in San Francisco. Additionally, Golden Bay’s crew cared for installed work by others, and took great care to make sure their metals were protected during transport. I would definitely like to work with them again.

I would like to extend my utmost gratitude to Mike and his crew of workers ( Golden Bay Fence Plus ) for installing the new fences at Rio Vista. Thank Mike and his crew for their hard work and dedication since June 16, 2022. I’ve seen lots of contracted crews at Rio Vista in the years that I have worked here. They would leave the place unkept, tools left out, gates left open etc. Mike’s crew has always been polite, professional, well mannered and gentlemen. Not one time did they leave any of the areas that they were working at unkept, they cleaned up and made sure the gates were closed and locked. If it were left up to me I would have Mikes men (Golden Bay Fence Plus) contracted to do all MDUSD schools that need new fencing.
