When enjoying outdoor life, the weather can often be unpredictable. In summer, a high-quality retractable awning can not only protect you from the sun but also provide reliable protection during rain, allowing you to enjoy outdoor time no matter what the weather is like. However, with a lot of awnings on the market, how can you get the one that is both aesthetically pleasing and durable for rainy days?
No worry. In this article, LIDA OUTDOOR‘s product manager shares how to select the best waterproof retractable awning and recommends several high-performance products to help you enjoy your outdoor space even on rainy days. [Of course, some other types of awning, such as polycarbonate awning, can also protect you from heavy rain, read to know more about awning types >]
What Factors To Consider When Choosing Rain-Proof Retractable Awnings
As a retractable awning manufacturer, we at LIDA OUTDOOR often communicate with end users in Europe and North America. One of the most frequently asked questions is: “Can fabric awnings really withstand rain?” Based on years of design and manufacturing experience, our answer is: yes — if you pay attention to the following three key aspects.
1. Waterproof Performance of Awning Fabrics
When selecting a retractable awning for rainy days, the fabric choice is crucial. High-quality fabrics not only provide reliable rain protection but also ensure the awning’s durability and longevity. Polyester fabric is one of the most commonly used materials for awnings due to its excellent waterproof and weather-resistant properties.
The Coatings of Polyester
Polyester fabrics treated with special coatings such as Polyurethane (PU), Polyamide (PA), or Acrylic significantly enhance their waterproof performance. These coatings effectively block rain penetration and improve tear resistance and abrasion resistance, ensuring the awning remains in good condition even in harsh weather.

Coating Type | Advantages | Disadvantages |
Polyurethane (PU) | Excellent waterproofing, flexible, and low temperature resistance | Less breathable |
Polyamide (PA) | Lightweight, good flexibility, decent waterproofing | Not as waterproof as PU, more prone to wear |
Acrylic | Good waterproofing, UV-resistant, and eco-friendly | Less abrasion-resistant, less flexible than PU |
Thickness and Density Matter
Additionally, the thickness and density of the fabric are important factors affecting its waterproof performance. Thicker fabrics typically offer better waterproof capabilities and higher durability, while high-density weave structures better prevent water penetration. Therefore, when choosing an awning, pay attention to the fabric’s Denier (D) and Threads per Inch (TPI). Also, opt for fabrics with mildew and UV resistance for comprehensive protection and extended service life.
Index | Unit | Description |
Denier (D) | D | Indicates the thickness of the fiber; higher values mean thicker fabric. Common range: 10s to hundreds of D; outdoor fabrics usually range from 150D to 600D. |
Threads per Inch (TPI) | TPI | Indicates the number of threads per square inch; higher values mean denser fabric. Common range: tens to hundreds of TPI. |
Denier (D) | Thickness Description | Suitable Scenario |
75D | Thin | Linings, lightweight windbreakers |
150D | Medium | Daily clothing, regular outdoor gear |
300D | Thick | Outdoor tents, awnings, and mountaineering gear |
600D | Very thick | Tool bags, high-strength outdoor equipment |
Threads per Inch (TPI) | Density Description | Suitable Scenario |
50 TPI | Low density | Good breathability, suitable for ventilated applications |
100 TPI | Medium density | Suitable for daily use, balanced waterproofing and breathability |
200 TPI | High density | Excellent waterproofing and wind resistance, suitable for outdoor equipment |
300 TPI | Very high density | Best waterproofing and wind resistance, suitable for extreme weather conditions |
2. Durability of the Awning Frame
The frame structure and support system are equally crucial when selecting a waterproof retractable awning.
Awnings exposed to rainy conditions must endure both the downward force of accumulated water and the pressure of strong winds. That’s why durable frame materials matter — they provide reliable structural support while resisting rust, corrosion, and environmental wear. A well-built frame not only ensures stability in bad weather but also greatly extends the overall lifespan of the awning.

When it comes to frame materials, most waterproof retractable awnings use one of two main options:
- Aluminum alloy frames are a popular choice thanks to their lightweight, rust-resistant properties. They’re easy to install, operate smoothly, and perform well even in consistently wet environments.
- Heavy-duty steel frames, often treated with anti-rust coatings, offer greater strength and structural stability. They’re ideal for awnings that need to support more weight or face harsher weather conditions.

Of course, frame design is just as important as material choice. Some models feature reinforced support rods that help distribute pressure evenly, reducing the risk of frame deformation or collapse under heavy rain or wind. Additional elements like wind-resistant strips and enhanced mounting systems also play a key role in improving the awning’s durability, ensuring it stays firmly in place, even during storms.
3. Drainage Design
Effective drainage design is key to preventing water accumulation on the canopy. A quality retractable awning often features a slanted canopy design or built-in drainage systems that allow rainwater to flow away quickly, preventing damage to the awning. Proper slant angles ensure rainwater naturally runs off the canopy, reducing the risk of water accumulation.

Additionally, some awnings are designed with dedicated drainage channels and holes, ensuring quick drainage during heavy rain and preventing water buildup that could deform or damage the canopy. Built-in drainage systems typically include hidden drainage channels within the frame, guiding rainwater to the ground or drainage points, keeping the awning dry and stable in the rain. This design not only enhances functionality but also provides users with peace of mind.
