Whether you’re a seasoned DIY enthusiast or a beginner, our insights will help you make an informed decision, ensuring your fly net stands the test of time and elements.
Let’s go…
Understanding Fly Nets
What is a Fly Net?
Insect screens, also known as fly nets, cover the openings of a structure, such as windows or doors, to prevent insects from entering while allowing air flow. Nets provide a barrier without compromising ventilation in areas where flying insects are a nuisance or health hazard.
Primary Uses of Fly Nets
- Preventing insects from entering homes or other structures.
- Allowing for natural ventilation and light.
- Enhancing comfort and hygiene by reducing the need for chemical insect repellents.
Significance of Material Choice
Material plays a significant role in the effectiveness of a fly net. The right metal determines the net’s strength and durability, as well as its visibility and aesthetics. A net’s choice of metal determines its weather resistance, maintenance requirements, and longevity.
Any of the metal mesh options mentioned in the blog would be suitable. But which would work best for your project?
Common Metals Used in Fly Nets
- Aluminum: Popular for its lightweight and rust-resistant properties.
- Stainless Steel: Known for its strength and durability.
- Copper: Offers a unique aesthetic with natural rust resistance.
- Galvanised Steel: A cost-effective option with decent durability.

Key Factors in Choosing Metal for Fly Nets
Durability
Rust and corrosion resistance are closely related to the longevity of a fly net. Due to their high rust resistance, metals such as stainless steel and aluminum are ideal for long-term outdoor use. A product must also be able to withstand physical stress without deforming or breaking as part of its durability.
Mesh Size
An effective fly net depends on the mesh opening size. It is possible to weave or weld a variety of metals into various mesh sizes, affecting their ability to keep out insects of varying sizes. Choosing the right metal affects the precision with which mesh sizes can be maintained over time.
Ease of Handling
In DIY projects, the workability of the metal is crucial. Metals like aluminum are easier to cut and shape, making them ideal for home projects. Stainless steel, for example, may require more specialised tools and techniques.
Aesthetic Appeal
The appearance of the metal is an important consideration, especially for residential applications. Metals like copper offer a distinct look that can add to the aesthetic value of a property. The metal’s ability to retain its appearance over time, resisting fading or discoloration, also plays a significant role.
Metal Options for Fly Nets

- Properties: Even though fibreglass is not a metal, it plays a significant role in fly nets. It is a composite material made from extremely fine fibres of glass. The material is lightweight, noncorrosive, and versatile.
- Advantages: Fly nets made of fibreglass have the advantage of minimising light and visibility obstruction. In humid climates, especially, it is resistant to rust and corrosion. For DIY projects, fibreglass is also relatively easy to cut and install.
- Potential Downsides: Under stress, fibreglass may become brittle and tear. In addition, prolonged exposure to sunlight can cause it to degrade. Even though it has good corrosion resistance, it is not as strong as metals like stainless steel.
- Properties: Known for its silver-white appearance, aluminum is a lightweight, malleable metal. Due to its non-ferrous nature, it does not rust.
- Advantages: Due to its lightweight, aluminum is easy to handle and install, making it ideal for DIY projects. In humid environments, it also provides excellent corrosion resistance.
- Potential Downsides: Despite its durability, aluminum can bend or dent under force. A dull patina may also develop over time, reducing its aesthetic value.


- Characteristics: Iron, chromium, and nickel make stainless steel an exceptionally strong and corrosion-resistant alloy.
- Benefits: Stainless steel is known for its durability. Fly nets made from this material are less likely to warp or degrade over time.
- Limitations: DIY enthusiasts may find it challenging to work with due to its strength. Additionally, it is generally more expensive than aluminum or galvanised steel.
- Unique Qualities: Copper stands out for its distinctive reddish-brown color, which develops a green patina over time due to oxidation.
- Pros: Natural corrosion resistance and antimicrobial properties make copper a hygienic choice. Adding it to any setting adds a unique aesthetic.
- Cons: Due to its softer and more malleable nature, it is less durable than stainless steel. Additionally, copper is one of the more expensive metals.


- Overview: Galvanised steel is steel coated with a layer of zinc to prevent rusting. This process enhances its durability.
- Strengths: Compared to plain steel, it’s more robust and corrosion-resistant. Additionally, galvanised steel is more affordable than stainless steel and copper.
- Weaknesses: It is possible for the steel underneath to rust if the zinc coating wears off. Galvanised steel also has a less refined appearance than other metals.
Comparative Analysis
Ultimately, each metal has its own advantages. Galvanised steel and aluminum are cost-effective and easy to work with, making them ideal for DIY enthusiasts. Copper offers a unique aesthetic and natural antimicrobial properties, while stainless steel is known for its strength and durability. It depends on the individual’s budget, durability, appearance, and workability requirements.
Practical Tips for DIY Fly Net Projects
Measuring and Cutting Metal Mesh
- Measure the area where the fly net will be installed accurately.
- Use appropriate tools such as metal snips for aluminum or a hacksaw for stainless steel.
- Wear gloves and safety goggles to protect from sharp edges.
We recently produced a simple video showing how mesh of this kind of size can be cut easily with scissors.
Installation and Maintenance
- Ensure the frame is sturdy enough to support the metal mesh.
- Secure the mesh tightly to prevent gaps where insects could enter.
- Regularly inspect for any damage and clean the mesh with a soft brush or cloth to remove dust and debris.
Safety Precautions
- Always work in a well-ventilated area.
- Be cautious of sharp edges while handling and cutting metal mesh.
- Dispose of any metal offcuts safely to prevent injury.
Cost-Effectiveness and Sustainability
Cost Implications
The cost of metal for fly nets varies significantly. For larger projects or those with limited funds, aluminum and galvanised steel are more budget-friendly. While stainless steel and copper are more expensive, they offer greater durability and aesthetic value, which may justify their higher price over time.
Sustainability Aspect
Metals’ entire lifecycle should be considered when assessing their environmental impact. Aluminum and steel are highly recyclable, reducing their environmental impact. While copper is less commonly recycled, its long lifespan can offset its initial environmental impact. Zinc coatings are responsible for galvanized steel’s sustainability. Choosing a sustainable option not only benefits the environment but can also be a selling point for environmentally conscious consumers.
To conclude, choosing the right metal for your DIY fly net requires balancing durability, functionality, aesthetic appeal, and cost-effectiveness. Many people choose aluminum due to its ease of handling and resistance to corrosion. While stainless steel stands out for its strength and longevity, copper has an aesthetic appeal and antimicrobial properties. Another viable option is galvanised steel, thanks to its robustness and affordability. Depending on your specific requirements, environmental conditions, and budget, each metal has unique advantages and potential downsides.
