Types of Bollards
1. Surface Mounted Bollards
Surface mounted bollards are ideal for installations where excavation is not feasible. They are bolted to the surface, making them easy to install and relocate. These bollards are commonly used in parking lots and pedestrian walkways, providing a clear visual barrier without permanent alterations to the ground.
2. Pour in Place Bollards
Pour in place bollards are designed for permanent solutions and require careful setting in concrete. This type ensures maximum stability and durability, making them suitable for high-traffic areas and construction sites, where protection against vehicle intrusion is critical.
3. Removable Bollards
Removable bollards offer flexibility in areas with shifting access needs. They can be manually moved or equipped with folding mechanisms, allowing for vehicular entry when necessary. These bollards are often used in events or temporary setups where the area may need to be reconfigured frequently.
4. Bollard Covers
Bollard covers are an efficient way to enhance the appearance of existing bollards while minimizing maintenance efforts. Available in various colors, they can hide wear and tear on older concrete or steel bollards, making them look new and vibrant.
5. Decorative Bollards
Decorative bollards serve both functional and aesthetic purposes. They come in various designs and colors, adding an appealing touch to professional buildings, apartment complexes, and storefronts. These bollards not only enhance safety but also contribute to the overall visual appeal of the environment.
Materials Used in Bollard Manufacturing
Bollards are constructed from a variety of materials, each selected based on the specific requirements of the application.
Steel
Steel bollards are robust and offer significant protection. They are often used in high-risk areas where vehicle impact is a concern. The durability of steel makes it suitable for long-term use, and it can withstand harsh weather conditions.
Concrete
Concrete bollards provide a permanent and sturdy solution for traffic management and safety. They are often used in construction zones and areas requiring high levels of security.
Recycled Plastic
Recycled plastic bollards are lightweight and flexible, making them an excellent choice for environments where safety is paramount but impact resistance is also needed. They are designed to bend rather than break upon impact, minimizing damage to vehicles and the bollard itself.
Cast Iron
Cast iron bollards are primarily used for decorative purposes. They offer a classic look while providing adequate protection in pedestrian areas. Their heavy-duty nature makes them suitable for areas where aesthetic appeal is essential.
Stainless Steel
Stainless steel is favored for its corrosion resistance and sleek appearance. It is commonly used in decorative and high-visibility applications, combining functionality with modern design.
Installation Techniques
Surface Mounted Installation
Surface mounted bollards are installed using bolts or plates anchored to the pavement. This method allows for quick installation without the need for extensive excavation.
Concrete Pouring
For pour in place bollards, the installation involves digging a hole, placing the bollard, and then filling the hole with concrete. This method ensures the bollard is securely anchored and can withstand significant force.
Removable Bases
Removable bollards may come with bases that allow for easy installation and removal. Some designs include mechanisms that enable the bollard to fold down or be taken out entirely, providing versatility in access control.
Technical Features Comparison
| Feature | Surface Mounted | Pour in Place | Removable | Bollard Covers | Decorative |
