When it comes to safeguarding our gardens from unwanted animal intrusions, choosing the right fence is crucial. As a supplier of plastic black garden fences, I often encounter customers wondering if these fences are strong enough to keep out animals. In this blog post, I will delve into the factors that determine the strength of plastic black garden fences and their effectiveness in deterring various animals. Plastic Black Garden Fence

Understanding the Material: Plastic Black Garden Fences
Plastic black garden fences are made from high – quality plastic materials, which are typically engineered to be durable and long – lasting. The black color not only gives a sleek and modern look to the garden but also provides some level of UV protection, preventing the fence from fading or becoming brittle under prolonged sunlight exposure.
One of the key advantages of plastic is its resistance to corrosion. Unlike metal fences that can rust over time, and wooden fences that can rot, plastic fences retain their structural integrity even in harsh weather conditions, such as heavy rain, snow, or extreme heat. This durability contributes to their overall strength and ability to withstand external forces, including the attempts of animals to break through.
Factors Affecting the Fence’s Ability to Keep Out Animals
Fence Height
The height of a plastic black garden fence plays a significant role in keeping out animals. For smaller animals like rabbits and groundhogs, a fence with a height of around 2 – 3 feet may be sufficient. These animals are not great climbers or jumpers, and a well – installed plastic fence at this height can act as an effective barrier.
However, for larger animals such as deer or goats, a taller fence is required. Deer are known to be excellent jumpers, and they can clear heights of up to 6 – 8 feet. Therefore, if deer are a concern in your area, a plastic fence with a height of at least 7 feet is recommended. The sturdiness of the fence at such a height is also important; if the fence sways or bends easily, deer may be more likely to attempt to jump over it.
Fence Thickness and Strength
The thickness of the plastic material used in the fence affects its strength. A thicker plastic fence is generally more robust and can better resist the pushing, scratching, or chewing of animals. Fences with a thickness of around 2 – 3 millimeters are common, but for areas with a high density of animals or more determined pests, a thicker fence of 4 – 5 millimeters can provide added security.
Moreover, the design and construction of the fence can enhance its strength. Some plastic black garden fences feature internal reinforcement, such as steel or fiberglass rods, which significantly increase their resistance to the forces exerted by animals. These reinforced fences are more likely to withstand the impact of a large animal trying to push through or a smaller animal trying to gnaw on it.
Installation Quality
A beautifully designed and strong plastic black garden fence is only as good as its installation. Proper installation ensures that the fence is firmly anchored in the ground, leaving no gaps or weak points that animals could exploit. The fence posts should be driven deep into the ground, at least 1 – 2 feet for smaller fences and up to 3 – 4 feet for taller fences.
Using the right hardware, such as sturdy brackets and screws, to connect the fence panels to the posts is also essential. Loose connections can cause the fence to become unstable, making it easier for animals to break through. Additionally, proper alignment of the fence panels during installation prevents any vertical or horizontal gaps that small animals could squeeze through.
Effectiveness Against Different Types of Animals
Small Rodents
Small rodents like mice and rats can be a nuisance in gardens, nibbling on plants and burrowing under the ground. Plastic black garden fences, if installed correctly, can be effective in keeping them out. Ensuring that the fence extends at least a few inches below the ground level can prevent these rodents from burrowing underneath. Since these animals are relatively small and do not have the strength to break through a properly installed plastic fence, a standard – thickness plastic fence with a height of around 1 – 2 feet can provide sufficient protection.
Rabbits and Groundhogs
Rabbits and groundhogs are known for their digging and chewing habits. A plastic black garden fence with a height of 2 – 3 feet can act as a deterrent. The fence should be installed with a slight angle outward at the top to prevent rabbits from climbing over. To stop groundhogs from burrowing, burying the bottom of the fence at least 6 – 12 inches deep into the ground is advisable. The plastic material is often resistant to their chewing, and if the fence is of suitable thickness, it can withstand their efforts to break through.
Deer
Deer pose a greater challenge when it comes to fencing. As mentioned earlier, a tall fence of at least 7 feet is required. Some plastic black garden fences are reinforced to withstand the impact of a deer running into the fence. Additionally, using deterrents such as motion – activated lights or noise – making devices in combination with the fence can enhance its effectiveness. Although deer are powerful animals, a well – installed, strong plastic fence can make them think twice before attempting to enter the garden.
Dogs and Cats
For domestic dogs and cats, a plastic black garden fence can be a practical solution to keep them in or out of the garden. A fence with a height of 3 – 4 feet is usually sufficient to contain most small to medium – sized dogs. The smooth surface of the plastic fence makes it difficult for them to climb. Cats, on the other hand, are more agile climbers. Adding a cat – proofing feature, such as an overhang or anti – climb spikes on top of the fence, can make it more effective in keeping them out.
Conclusion

In conclusion, plastic black garden fences can be strong enough to keep out a wide range of animals if they are designed and installed correctly. Their durability, corrosion resistance, and customizable features make them a viable option for garden protection. However, it is important to consider the specific animals in your area and choose the appropriate fence height, thickness, and installation method.
