A Guide to Site Protection With Bollards
Whether you need bollards because of building or fire codes, the design of the building, traffic patterns, or safety concerns, you want to ensure you are getting the right product for your site requirements. From crash rated bollards to traffic pattern indicators, bollard design is critical in providing the ideal protection for your building. To find the right barrier for your project, our team at Ontario Bollards shares the following information.
Key Bollard Considerations
Safety bollards are an excellent way to provide guidance for traffic flow, protection for pedestrian traffic, and an additional security measure for the building entry. However, despite their efficacy as visual and physical guides for vehicles, particularly in public venues, they are often overlooked.
When these robust, reinforced metal posts are placed in front of buildings or other outdoor spaces, it not only cues drivers where to go, but provides a safe space for pedestrian walkways and protects storefronts. Gate bollards can be used to seal off roads, bike paths, or walking trails, while parking bollards can prevent drivers from accidentally rolling too far past the parking spaces.
To select the right bollard for your needs, consider the following factors for your site:
- Behavior of drivers
- Design of building and road
- Frequency of traffic
- Types of traffic
Types of Bollards & Their Advantages
The strongest bollards are steel pipe reinforced with concrete and installed in a concrete substrate. Collapsible or retractable bollards can allow vehicle access from specific directions while preventing access from others without removing them.
You may choose to install a permanent crash rated, high impact bollard to prevent vehicles from hitting pedestrians or damaging property. If you are using bollards to section off areas, a low impact bollard may be a better choice. For multi-use areas, consider removable bollards.
Regardless of the design and installation, there are many benefits to using bollards on your site:
- Protect drivers: Traffic bollards separate opposing traffic patterns on roadways and limit speed in dangerous areas.
- Light up dark spaces: Lighted bollards are often used around parks and near buildings to illuminate walkways at night.
- Prevent access: Bollards can be used either permanently or temporarily to designate pedestrian access or construction areas.
- Enhance appearance: The aesthetic appeal of bollards is vastly underrated. Design, placement, color, and lighting can highlight and enhance the look of both architecture and landscaping.
- Protect storefronts: You can protect storefronts from wayward vehicles with concrete reinforced steel pipe bollards. If the look doesn’t appeal to you, there is always the option for more attractive bollard covers.

K-Rated Bollards vs. M-Rated Bollards
Bollards are a common sight at the front of nearly any commercial building. Typically installed near entrances, these architectural structures protect pedestrians and buildings from damage caused by oncoming vehicles. They are available in numerous variations to suit different purposes, such as preventing cars from inadvertently ending up on the sidewalk, minimizing the risk of vehicles rubbing against buildings in drive-thrus, or stopping heavy-duty vehicles from ramming into high-security facilities. In applications where there is a high risk of vehicle impact, crash-rated bollards are generally installed. These bollards are commonly rated based on one of two crash rating systems: K-ratings or M-ratings.
The following article discusses the differences between these two bollard crash rating systems.
K-rating bollard standards were originally developed by the United States Department of State (DOS) in 1985 and later revised by the DOS and Department of Defense (DOD) in 2003. Bollards that complied with these standards needed to withstand impact from 15,000-pound payloads (approximately the size of a medium-duty truck) moving at 30, 40, or 50 mph, depending on the rating.
- K4-rated bollards stop 15,000-pound vehicles moving at 30 mph (48 kph).
- K8-rated bollards stop 15,000-pound vehicles moving at 40 mph (65 kph).
- K12-rated bollards stop 15,000-pound vehicles moving at 50 mph (80 kph).
Following 9/11 and an increasing interest in developing technology to guard against criminal/terrorist attacks on buildings, the DOS updated these standards in 2003 to focus on the bollard’s effectiveness at stopping a moving vehicle (given that it is moving within its speed range) from passing the barrier.
- K-rated bollards with L3 certification stop vehicles with less than 3 feet of penetration.
- K-rated bollards with L2 certification stop vehicles with between 3 to 20 feet of penetration.
- K-rated bollards with L1 certification stop vehicles with between 20 to 50 feet of penetration.
Bollards with no certification have an unknown level of penetration resistance.
Following the widespread installation of K-rated bollards, the American Society of Testing and Materials (ASTM) developed and introduced a more comprehensive bollard crash rating system that focused on a bollard’s ability to stop vehicle penetration through the barrier. This new system largely replaced the older K-rating system as it outlined speed and penetration ratings for a broader range of vehicles, including small passenger vehicles (2,430 lbs.), pickup trucks (5,070 lbs.), medium-duty trucks (15,000 lbs.), and heavy-duty vehicles (65,000 lbs.). However, many industry professionals continue to use the term “K-rating” when talking about barrier crash ratings for medium-duty trucks.
Bollards rated for medium-duty vehicles could receive M-ratings.
- M30-rated bollards stop 15,000-pound vehicles moving at 30 mph (48 kph).
- M40-rated bollards stop 15,000-pound vehicles moving at 40 mph (48 kph).
- M50-rated bollards stop 15,000-pound vehicles moving at 50 mph (48 kph).
They could also be certified regardless of how far a vehicle travels past the barrier.
- M-rated bollards with P1 certification stop vehicles with less than 3.3 feet of penetration.
- M-rated bollards with P2 certification stop vehicles with between 3.31 to 23 feet of penetration.
- M-rated bollards with P3 certification stop vehicles with between 23.1 to 98.4 feet of penetration.
- M-rated bollards with P4 certification stop vehicles with over 98.41 feet of penetration.
The revision of the rating standards and the replacement of old standards led to building designers and security experts putting more trust in the ability of M-rated bollards to resist high-speed, heavyweight impacts.

M-rated bollards—also commonly referred to as K-rated bollards—serve a critical role in anti-terrorism efforts. P1-certified bollards prevent 15,000 lbs. vehicles at a specific speed from penetrating the barrier beyond 36 inches, which helps minimize and/or eliminate the risk of injury to pedestrians and damage to buildings caused by oncoming cars and trucks.
