As a supplier of PVC mesh tarps, I often get asked about the snow-load capacity of these versatile products. Understanding the snow-load capacity is crucial, especially in regions prone to heavy snowfall. In this blog, I'll delve into what snow-load capacity means for PVC mesh tarps, the factors that influence it, and how to ensure you're choosing the right tarp for your snow-related needs.
What is Snow-Load Capacity?
Snow-load capacity refers to the maximum amount of snow weight that a PVC mesh tarp can safely support without tearing, sagging excessively, or failing structurally. It is typically measured in pounds per square foot (PSF) or kilograms per square meter (kg/m²). When snow accumulates on a tarp, its weight exerts pressure on the surface. If the snow load exceeds the tarp's capacity, it can lead to damage, which may compromise the protection it provides.
Factors Affecting Snow-Load Capacity
Material Thickness
The thickness of the PVC mesh tarp plays a significant role in determining its snow-load capacity. Thicker tarps generally have a higher capacity because they are more resistant to stretching and tearing under the weight of the snow. For example, a 14-mil PVC mesh tarp will be able to handle more snow than a 6-mil one. At our company, we offer a range of thicknesses to meet different snow-load requirements.
Mesh Density
Mesh density refers to the number of openings per square inch in the tarp. A higher mesh density means fewer and smaller openings, which can increase the tarp's strength and its ability to support snow. Tarps with a tighter mesh are less likely to allow snow to pass through, distributing the weight more evenly across the surface. However, it's important to note that a very high mesh density may reduce the tarp's breathability, which can be a concern in some applications.
Tarp Size and Shape
The size and shape of the tarp also impact its snow-load capacity. Larger tarps have a greater surface area, which means they will accumulate more snow. Additionally, irregularly shaped tarps may have areas where snow can accumulate more easily, creating uneven stress points. When installing a tarp, it's essential to consider these factors and ensure proper support to prevent excessive sagging.
Installation and Support
Proper installation and support are crucial for maximizing the snow-load capacity of a PVC mesh tarp. The tarp should be securely fastened to a stable structure using appropriate hardware, such as ropes, bungee cords, or grommets. It's also important to provide adequate support underneath the tarp, such as poles or frames, to prevent it from sagging under the weight of the snow. Without proper support, even a high-quality tarp may fail under heavy snow conditions.
Determining the Snow-Load Capacity for Your Needs
To determine the appropriate snow-load capacity for your PVC mesh tarp, you need to consider several factors, including the average snowfall in your area, the duration of the snowfall, and the specific application of the tarp. In regions with heavy snowfall, such as the northeastern United States or the mountainous areas of Canada, you'll need a tarp with a higher snow-load capacity. On the other hand, if you're using the tarp in a region with light snowfall, a lower capacity tarp may be sufficient.
It's also important to consider the intended use of the tarp. For example, if you're using the tarp to cover a vehicle or equipment, you may need a tarp with a higher snow-load capacity to protect against damage. If you're using the tarp for a temporary shelter or to cover a garden, a lower capacity tarp may be adequate.
Our PVC Mesh Tarp Offerings
At our company, we offer a wide range of PVC mesh tarps to meet different snow-load requirements. Our Printing Mesh Tarp is a popular choice for applications where visibility is important, such as outdoor advertising or greenhouse covers. It is made from high-quality PVC material and has a durable mesh design that can withstand moderate snow loads.

For heavy-duty applications, our Plastic Mesh Tarp is the perfect choice. It is made from thick, durable PVC material and has a high mesh density that can handle heavy snow loads. It is commonly used for covering large structures, such as warehouses or construction sites.
Ensuring Safety and Longevity
To ensure the safety and longevity of your PVC mesh tarp, it's important to follow some best practices. Regularly inspect the tarp for any signs of damage, such as tears or holes, and repair them promptly. Remove snow from the tarp as soon as possible after a snowfall to reduce the weight and prevent damage. If the snow is too heavy to remove manually, use a snow rake or a blower to clear the surface.
It's also important to store the tarp properly when not in use. Clean the tarp thoroughly and allow it to dry completely before folding and storing it in a cool, dry place. Avoid storing the tarp in direct sunlight or in a damp environment, as this can cause the material to degrade over time.
