12ft x 22ft x 25.1ft Right Triangle Shade Sail - High UV Protection

Our review of this custom size right triangle shade sail finds it best for homeowners and small businesses who need targeted sun protection with a tailored fit. The single biggest reason to buy is its combination of heavy-duty 200 GSM HDPE fabric and 95% UV blockage, which gives reliable shade and temperature reduction without feeling like a solid roof. Installation is flexible enough for patios, play areas, or garden seating, and the built-in reinforcement and stainless steel D-rings make it a practical long-term canopy solution.

Key Features

• 95% UV blockage: The fabric blocks up to 95% of harmful UV rays so outdoor spaces stay safer for longer use.
• 200 GSM HDPE construction: The heavier fabric provides commercial-standard durability and resists fraying with double-layer stitching.
• Temperature reduction: The sail lowers ambient temperatures by as much as 15 degrees compared to unshaded areas, improving comfort in summer.
• Stainless steel hardware: D-rings and reinforced edges offer reliable anchor points that hold up under wind and repeated use.
• Custom sizing: The product is made to order from D-ring to D-ring so it can be measured to fit irregular spaces for a neat finish.
• Water and air permeable: The breathable weave sheds some water and allows airflow, avoiding a sealed, rain-trap canopy.

Who It's For

The sail is ideal for homeowners, cafes, or community spaces that need a tailored triangular shade covering a specific area such as a patio corner, playground, or outdoor seating nook. Buyers who value color accuracy, durability, and straightforward installation will appreciate the stainless D-rings and reinforced edge construction.

Those who want a fully waterproof awning or a rigid roof replacement should look elsewhere, since this woven HDPE fabric is water permeable and designed for sun protection and airflow rather than complete rainproofing. Also, customers who prefer fixed metal frames rather than fabric spans may find a different solution more suitable.

Frequently Asked Questions

Is this sail waterproof?
Answer. The HDPE weave is water and air permeable, so it offers some rain shedding but is not fully waterproof like a solid awning.

How should I measure for a custom fit?
Answer. Measure from D-ring to D-ring for each side and allow recommended corner gaps of at least 0.5 ft from poles; reduce by 1 to 1.5 ft per side if needed per installation guidance.

How durable is the hardware?
Answer. Stainless steel D-rings and reinforced edges with double-layer stitching provide commercial-standard durability and resist fraying and wear under wind and sun.
