In the UK, parking-bollards are frequently used to regulate and control vehicle access in certain areas. Heavy-duty parking-bollards are designed to provide strong security and protection against unauthorised access or vehicle ramming.
These bollards are often installed in high-security areas such as government buildings, airports, commercial properties, and sensitive infrastructure sites.
Types of Heavy-Duty Bollards:
Here are some common types of heavy-duty parking bollards mostly used in the UK:
Fixed Bollards:
- These permanent bollards installed into the ground cannot be moved or retracted.
- They are typically made of durable materials such as steel or concrete to provide maximum security and a permanent barrier against vehicle intrusion.
- They are ideal for locations that require continuous security.
Retractable Bollards:
- These bollards types can be raised or lowered to allow or restrict access.
- They are often operated manually or electronically, providing flexibility in controlling entry points.
- They are often used in areas where occasional access is required.
Crash-Resistant Bollards:
- Designed to withstand impact from vehicles, crash-resistant bollards are often used in high-security areas.
- They are engineered to absorb and redirect the energy from a collision, minimising damage and maintaining their effectiveness.
Material & Coatings Used in HD Bollards:
Heavy-duty parking-bollards are typically made of robust materials to ensure durability and strength. The choice of material depends on factors such as the level of security required, environmental conditions, and aesthetic preferences. Common materials used for heavy-duty parking bollards include:
Steel:
Steel is a popular choice for heavy-duty bollards due to its strength and durability. Bollards made of steel can withstand high-impact forces and provide effective protection against vehicle intrusion.
Stainless steel is often used for its corrosion resistance, making it suitable for outdoor environments.
Concrete:
Concrete bollards are another sturdy option, and they are often used in areas where a more substantial and permanent barrier is required. They can be reinforced with steel for added strength.
Cast Iron:
Cast iron bollards are known for their durability and classic appearance. They are often used in historical or aesthetically sensitive areas.
Bollards with Impact-Resistant Coatings:
Some bollards are coated with impact-resistant materials, such as high-impact plastic or polyurethane, to absorb and disperse the energy from collisions. This can help minimise damage to both the bollard and the colliding vehicle.
Bollards with Warning Features:
Some heavy-duty bollards include reflective or LED features to enhance visibility, especially during low-light conditions.
Impact of HD Parking Bollards in the UK:
Understanding the impact resistance rating of bollards is crucial. In the UK, PAS 68 and IWA 14 are commonly referred to as standards for heavy-duty parking bollards.
PAS 68 provides a classification system for vehicle security barriers, while IWA 14 specifies the impact performance criteria for vehicle security barriers.
Automation of Heavy-Duty Bollards:
The integration of automated heavy-duty bollards with central security management systems allows for real-time monitoring and remote control. The automated functionality allows for precise control over the movement of the bollards, granting access only to authorised personnel or vehicles.
This controlled access not only prevents unauthorised entry but also enhances the efficiency of security protocols. This is especially important in high-security environments.
General Standards for HD Bollards:
In the UK, the standards and guidelines for heavy-duty bollards are typically outlined by various organisations and regulatory bodies. For heavy-duty bollards, you should look for relevant British Standards that provide specifications for design, materials, and installation such as BS 6543 and BS 8417. Here are some general guidelines for the measurements of heavy-duty bollards:
Height:
The height of heavy-duty parking bollards is an important factor for visibility and deterrence. Heights typically range from 36 inches (3 feet) to 48 inches (4 feet) above ground level. However, in high-security applications, taller bollards may be used.
Diameter/Width:
The diameter or width of heavy-duty bollards is influenced by the level of impact resistance required. Standard diameters can range from 6 inches to 12 inches or more. Thicker and wider bollards are generally more resistant to vehicle impacts.
Spacing:
The spacing between bollards is essential to prevent vehicles from passing through. In areas where high security is required, bollards may be spaced more closely to create an effective barrier.
Conclusion:
In the UK, heavy-duty parking bollards play a vital role in enhancing security and managing parking spaces effectively. The visual deterrent and strong impact resistance features of these bollards are instrumental in minimising vandalism and preventing unauthorised parking, fostering a safer and more secure public space.
