Our padel court is starting to rust: causes in coastal environments and how to solve it

Corrosion in padel courts is one of the most critical factors affecting the real lifespan of a sports installation, especially in coastal areas or environments with high humidity.

Although it is often seen as a purely aesthetic issue, in reality it is a slow, progressive process that can ultimately impact the structure, safety, and—above all—maintenance costs in the medium and long term.

In this article, we clearly and practically explain why corrosion appears, how it manifests in a padel court, the common misconceptions around it, and—most importantly—the real solutions that effectively help control it.

 

What corrosion is in a padel court

Corrosion is a natural process. Metals, especially steel, react with oxygen and moisture in the environment until they return to their most stable state: rust.

In a padel court, this process typically affects very specific components:

• Main steel structure
• Bolts and fastening systems
• Welds and connection points
• Base plates and ground anchors
• External auxiliary elements

The speed at which it appears depends on three key factors: the environment, the materials used, and the level of protection applied from the beginning.

 

Why coastal areas accelerate corrosion

Courts located near the sea are exposed to a particularly demanding environment.

The main reason is the presence of salt in the air (chlorides), which travels through the atmosphere and settles on metal surfaces. This salt gradually breaks down protective layers on steel, accelerating the onset of oxidation.

On top of that, coastal environments usually combine several critical factors:

• Constant high humidity
• Salt particles suspended in the air
• Temperature changes that cause condensation
• Wind that carries corrosive agents

When all these factors combine, metal degradation accelerates significantly.

 

Where corrosion usually appears first

 

It is important to understand that corrosion does not appear evenly. It always starts in specific, high-risk areas of the structure:

1. Bolts and fastening systems

Highly exposed areas where moisture often accumulates.

2. Welded joints

If not properly protected, these can become vulnerable points.

3. Anchors and base plates

Contact with the ground and potential water retention make them sensitive areas.

4. Areas with poor water drainage

Any point where drainage is inefficient increases the risk.

 

Common myths about corrosion

Over time, several misconceptions have become widespread:

“It’s only a visual issue”
Not exactly. Over time, it can reduce steel thickness and affect structural performance.

“It only happens in old courts”
Incorrect. Poor material selection or inadequate protection can lead to early corrosion.

“Galvanising solves everything”
Galvanising helps significantly, but it is not permanent. Its effectiveness depends on coating thickness and environmental exposure.

“New structures don’t need maintenance”
All outdoor metal structures require periodic inspection, especially in humid or coastal environments.

 

What really determines corrosion resistance

There is no single factor. Durability depends on several key decisions made at the design stage:

• Type and quality of steel
• Chosen anti-corrosion protection system
• Structural design and water drainage strategy
• Quality of bolts and auxiliary components
• A properly planned preventive maintenance programme

When any of these elements fail, deterioration appears earlier than expected.

 

Real solutions to prevent and control corrosion

The good news is that corrosion can be effectively managed when approached correctly.

It is not about eliminating it completely, but about controlling it.

The most effective solutions are:

✔️ Designing with the environment in mind from the start
A court in an indoor location is not designed the same way as one in a coastal area.

✔️ Using high-quality galvanised steel
Hot-dip galvanising is one of the most effective protective barriers.

✔️ Adding additional protective systems when required
Industrial coatings or multi-layer systems increase resistance in marine environments.

✔️ Protecting critical points specifically
Bolts, joints and drainage areas require special attention.

✔️ Implementing preventive maintenance
Regular inspections help identify issues before they develop further.

 

The real cost of corrosion

The impact of corrosion is not limited to a single rusted component. It can also involve:

• Replacement of structural elements
• Unplanned repair interventions
• Temporary closure of the facility
• Damage to the club’s image
• Reduced lifespan of the project

That is why prevention is always the most cost-effective strategy.

 

Ultimately, durability is not a matter of luck. It is the result of doing things properly from the very beginning.
