Automated Gates for Coastal Properties: Protecting Against the Elements

Coastal properties offer the allure of stunning views and the tranquil sound of waves, but they also present unique challenges when maintaining infrastructure, such as automated gates. The harsh coastal environment, characterised by salt-laden air, high humidity, and strong winds, can significantly impact the durability and functionality of these gates. This article will delve into the specific challenges coastal properties face and provide guidance on choosing and maintaining automated gates that can withstand these conditions.

Challenges of Coastal Environments

Salt Corrosion

Salt in the air is one of the most significant challenges for coastal properties. Salt accelerates the corrosion of metals, leading to rust and deterioration. This is particularly problematic for automated gates’ moving parts and electrical components, which can suffer from reduced functionality and increased maintenance costs.

High Winds

Coastal areas are often subject to strong winds, which can particularly damage gates. High winds can cause gates to swing uncontrollably, leading to structural damage and safety risks. It is crucial to select gates designed to withstand these forces and remain stable.

Humidity and Moisture

The high humidity levels typical of coastal areas can also harm automated gates. Moisture can infiltrate electronic components, causing malfunctions and reducing the lifespan of the gate’s operating system. Ensuring that these components are well-protected against moisture is essential for long-term reliability.

Choosing the Right Materials


Aluminium is another suitable material for coastal gates. It is naturally corrosion-resistant and does not rust like iron or steel. Additionally, aluminium gates are lightweight, which makes them easier to automate and less likely to be affected by strong winds.

Protective Coatings and Finishes

Applying protective coatings and finishes to automated gates can significantly enhance their resistance to the elements. Powder coating, for example, provides a durable, long-lasting finish that protects against corrosion and UV damage. Regular maintenance, such as repainting and touch-ups, can also help maintain the integrity of the gate’s surface.

Maintenance Tips for Coastal Gates

Regular Inspections

Frequent inspections are essential to identifying and addressing potential issues before they become major problems. Look for signs of rust, wear, and tear and ensure that all moving parts are functioning smoothly.


Regular lubrication of hinges, rollers, and other moving parts can help prevent corrosion and ensure smooth operation. Use lubricants that are specifically designed for use in marine environments.

Protecting Electronics

Ensure that all electronic components, such as motors and control panels, are well-protected against moisture. Use weatherproof enclosures and consider installing a secondary barrier, such as a rubber gasket, to keep out water and salt.


Regularly clean your automated gate to remove salt and debris. Use fresh water to rinse off accumulated salt, and avoid using harsh chemicals that can damage the protective coatings.


Automated gates for coastal properties require careful consideration and maintenance to ensure they remain functional and attractive despite the harsh conditions. By selecting suitable materials, applying protective coatings, and performing regular maintenance, you can protect your investment and enjoy the security and convenience of automated gates for years to come. Implementing these strategies will help mitigate the effects of salt corrosion, high winds, and humidity, ensuring your gates remain in excellent condition.
