How Bollards Are Built to Endure Harsh Weather Conditions

Bollards are vital components of urban infrastructure, serving as protectors of public spaces, buildings, and pedestrians. Whether you're in a bustling city or a coastal area, bollards play a key role in maintaining safety by controlling vehicle access and preventing accidental damage. But did you know that bollards also need to be designed to withstand extreme weather conditions? In the UK, where harsh weather can vary from strong winds and heavy rain to freezing temperatures and salt exposure, bollards must be able to endure these challenges.

In this blog, we’ll explore how bollards are built to stand up to the elements, including the materials, engineering techniques, and practical design features that ensure their resilience. We’ll also discuss how bollard covers and correx board printing play their part in enhancing bollard durability.

1. What Are Bollards and Why Do They Matter?

What is a Bollard?

Bollards are short, vertical posts that are typically installed to control or direct traffic and protect pedestrian spaces. They’re often seen around buildings, parks, or outdoor public areas. Bollards help prevent vehicles from accidentally running into these spaces while also providing protection against deliberate impacts, like vehicle attacks.

Why Are Bollards Crucial?

In busy urban settings, bollards are often used to protect pedestrian zones from vehicles, whether for security purposes or to prevent damage to buildings and walkways. They are also used as decorative elements to improve the aesthetic of public spaces. Whether acting as barriers or enhancing safety features, bollards are an essential part of infrastructure.

2. The Impact of Harsh Weather on Bollards

Weather Hazards for Bollards

Bollards face a constant battle against extreme weather conditions, particularly in regions like the UK. Some of the weather challenges that bollards must endure include:

• Heavy Rain and Flooding: Persistent rain or sudden floods can cause damage to bollards made from susceptible materials, such as steel or wood, leading to rust or structural damage.
• Snow and Ice: Snow and ice can accumulate around bollards, exerting pressure on the materials, and in freezing conditions, can even cause cracks or expansion.
• High Winds: High winds, particularly in coastal or exposed areas, can weaken poorly designed bollards. The physical force of the wind can stress the materials or cause them to shift.
• Temperature Fluctuations: Frequent changes between hot and cold temperatures can cause materials to expand and contract, leading to cracking, weakening, or even warping of bollard surfaces.

Consequences of Weather Damage

Without the proper weather-resistant features, bollards can quickly degrade. The harsh elements can lead to:

• Corrosion and Rust: Metal bollards exposed to rain or saltwater can corrode over time, leading to structural instability.
• Loss of Structural Integrity: Bollards that are not built to withstand freezing temperatures or sudden weather changes can lose their ability to protect the intended area.
• Increased Maintenance Costs: Bollards that don’t endure the elements effectively require frequent repairs or replacements, which can be costly over time.

3. Materials Used in Weather-Resistant Bollards

1. Steel Bollards

Steel is one of the most common materials used for bollards. Steel bollards are strong and durable, ideal for withstanding impact. However, they must be properly treated to resist the effects of weather:

• Corrosion Protection: Steel bollards are often galvanised to prevent rust. The galvanising process coats the steel with a layer of zinc, providing protection from corrosion caused by rain or saltwater exposure.
• Powder Coating: Steel bollards are often powder-coated to create a weather-resistant surface that prevents rust and damage from UV rays.

2. Concrete Bollards

Concrete bollards are highly durable and can endure extreme weather conditions such as heavy rain, snow, and freezing temperatures. Concrete’s dense structure makes it ideal for outdoor areas exposed to harsh weather. However, concrete must be reinforced to ensure it doesn’t crack due to freezing and thawing cycles.

• Impact Resistance: Concrete bollards are highly resistant to impact, making them suitable for high-traffic areas.
• Temperature Resistance: Concrete can handle extreme temperature fluctuations when reinforced with the right materials.

3. Plastic and Composite Bollards

Plastic bollards, often made from polyethylene, and composite bollards are lightweight alternatives to metal and concrete options. These bollards resist corrosion and UV damage, making them a good choice for areas prone to saltwater or high humidity.

• Corrosion-Resistant: Plastic and composite bollards are highly resistant to water damage, rust, and general wear.
• Lightweight and Easy to Maintain: These bollards are easier to install and require less maintenance than their metal or concrete counterparts.

4. Engineering Design Features for Weather-Resistant Bollards

1. Corrosion Protection Coatings

For bollards to endure extreme weather, they need to be protected against corrosion, which is a major concern in areas with high humidity or salt exposure. Bollard covers made from corrosion-resistant materials are often used to provide an extra layer of protection. These covers act as shields, preventing the bollard from coming into direct contact with the elements.

2. Reinforced Bollard Designs

In areas with high wind speeds or heavy traffic, bollards can be reinforced with steel or composite supports. Internal reinforcements help ensure that bollards maintain their integrity during storms or impacts. Reinforced bollards can also absorb shock and impact, preventing structural damage.

3. Anti-Freeze Design Features

Bollards in colder regions must be designed to withstand freezing temperatures. Special coatings, such as water-resistant sealants, are used to prevent water from accumulating inside the bollard. Drainage systems are sometimes added to bollards to allow water to flow away from the base, preventing freezing and cracking.

5. Aesthetic Considerations for Weatherproof Bollards

1. Surface Treatments for Aesthetic and Protection

In addition to offering protection against weather conditions, bollards are often treated with textured finishes or custom colours for aesthetic purposes. These treatments help maintain the bollard’s appearance and protect it from water and dirt accumulation, ensuring it stays clean and functional.

• Decorative Bollard Covers: Bollard covers can also be used for decorative purposes. These covers come in various materials and designs, offering both protection and an aesthetically pleasing look.

2. Customisation for Harsh Environments

In environments like coastal areas or areas prone to extreme weather, bollards are often customised with protective coatings to handle specific environmental challenges. Custom bollard covers can also be designed for aesthetic appeal, making them a functional and decorative solution.

The Role of Correx Board Printing in Bollard Protection

1. What is Correx Board Printing?

Correx board printing refers to the process of printing custom designs or messages onto corrugated plastic boards (Correx). These boards are lightweight, weather-resistant, and durable, making them an ideal material for bollard covers in areas exposed to harsh weather.

2. Benefits of Correx Board Printing for Bollards

• Temporary Protection: Correx board printing offers a cost-effective way to provide temporary protection to bollards, particularly in areas where environmental conditions change frequently.
• Weatherproofing: The material is resistant to moisture, UV rays, and physical damage, ensuring that bollards remain protected against harsh weather conditions.
• Customisation: Correx board printing allows for easy customisation, including the addition of logos, warnings, or other relevant information that can be printed directly onto the bollard covers.

3. Cost-Effectiveness and Ease of Installation

One of the main advantages of using correx board printing for bollard covers is the cost efficiency and ease of installation. Unlike permanent bollard coverings, correx board printed covers can be easily applied and removed, making them ideal for temporary protection during specific weather conditions.

Conclusion: Ensuring the Longevity of Bollards in Harsh Weather

Bollards are essential in protecting public spaces and infrastructure, but their ability to withstand harsh weather conditions depends on the materials, design, and maintenance strategies used. From bollard covers to correx board printing, various design elements are implemented to enhance their weather resistance. Understanding how bollards are built and maintained to endure extreme conditions ensures they remain functional, safe, and durable for years to come.
